There are a few places in Fallout 3 where having a higher Perception will trigger the ability to notice certain things upon entering a room or building. Occasionally this can lead to useful discoveries.

Does anyone have any examples of these kind of situations? So far, I only know of the one regarding the Anchorage War Memorial loot—Preceding unsigned comment added by PwnzerfaustMonk (talkcontribs). Please sign your posts with ~~~~!

I think your perception influences what you notice about the Wests' corpses in Blood Ties. With high perception you get something like "it looks like somebody's been gnawing on the bones", with low PE just "they're dead". Not exact quotes of couse, just to illustrate the point. -- Porter21 (talk) 09:46, 20 February 2009 (UTC)
I think medicine is what determines if you see the bite marks on those corpses or not. I thought perception was only good for getting things to show on your radar. Dcruze 09:53, 20 February 2009 (UTC)
You are right, Medicine is the determining factor (0-29 gives no clues, 30-49 gives 1 clue, 50-69 gives 2 clues, 71-89 gives 3 clues, 90+ gives all 4 clues). No idea then, usually don't play chars with high Perception. -- Porter21 (talk) 10:05, 20 February 2009 (UTC)
Along with Charisma and (debatably) Intelligence, Perception is one of the pointless SPECIALs. The only good it does is increase the linked skills' values. The radar detection thing is pretty useless really, and even if you do find it useful, you can just get dogmeat as a follower (who has a high perception) and he will detect- this renders your perception useless. Still it accesses some good perks such as Sniper and Better Criticals.81.156.11.193 01:14, 21 February 2009 (UTC)
I highly disagree! I find the detection very useful as I prefer to stealthly snipe my enemies from a distance so I can get the sneak bonus and so I can get multiple shots off before they get shoot at me/hit me if the first shot doesn't kill them. I don't use Dogmeat because he always seems to die on me within the 3 fights I get into, and because I don't want him to ruin my stealth. And don't mention "Puppies!". Even though I have Broken Steel, it's not availible untill level 24 (I think). These conditions factor into me needing that detection range and I love it.
PS: Don't push your opinion into others as if it were fact. I find it highly rude, arrogent, and insensitive. Sometimes I just don't understand other people… --TheREALBloodscar 10:12, 26 May 2009 (UTC)

Not sure I like how the linked headers look. You never see anything like that on Wikipedia, and this Wikia is supposed to follow their manual of style. Dcruze 09:53, 20 February 2009 (UTC)

Well, they're not really necessary now that we have the game icons. Ausir 10:12, 20 February 2009 (UTC)

View Distance[]

"Be aware that a high Perception with a low view distance may be disadvantageous, as you will "sense" your enemies but not know where they are."

What's means "low view distance"? Isnt the range of view the same for all Players? --VikingII 12:22, 16 April 2009 (UTC)

They mean like indoors with walls in the way, low light areas, etc. Where something is hindering your view as a player, not as a character.

In a contrast to that, what about how far your perception detects (1=x meters, 10=y meters)?87.60.42.74 14:58, September 22, 2009 (UTC)

Compass is ass backwards.[]

Just went looking for Dogmeat. Set a marker at where Scrapyard would be. Ended up at some Enclave training place with an Enclave Research Computer sitting outside. As it turns out, my compass led me too far, and it seemed to show me that Scrapyard was in the dead center of the outdoor research area. Upon facing the correct direction to Scrapyard (North/northeast), my compass's Marker (which was set in the North/northeast) was completely ass backwards, and pointing me South/Southwest.

Can You use Mentats to......[]

temporarily boost your perception to get a perk? is it possible? or does the perk only go from the base special, and not the current?

   You cannot; perks only take into account your non-boosted stats(excluding bobbleheads and items that mimic bobbleheads such
   as the lucky eight ball). Keemonto 13:40, September 21, 2009 (UTC)

New Vegas Bug?[]

I don't where to put this, but here goes.

I have noticed a few times that when I've been in a cave or anywhere else underground I can't 'sense' enemies on my radar any more. I have ED-E and 7 Perception. Works fine outside. Can't remember when I first noticed and I don't think it's every time. Just wondering if anyone has noticed this? --Webley 06:29, October 28, 2010 (UTC)

EDIT: On further investigation, it seems it is just reduced not gone completely. Still, curious if this is a bug or a feature.

I have noticed this to. I think it's a feature. Outside, you can hear and see, while inside you can't see through walls and the cramped space makes hearing difficult. 50.8.131.242 02:58, November 6, 2010 (UTC)

This happens to me outdoors as well as indoors, on the PC. 8 Perception and ED-E as a companion. 85.167.97.19 21:12, February 2, 2011 (UTC)

New Vegas Accuracy[]

The in game description and the Fallout: New Vegas primary statistics page both state that perception has an effect on accuracy. The only mention of New Vegas in this article is to point out that it doesn't. Neither page sites a source or research or any specifics. Can anyone shed a little light here? 67.149.196.9 05:06, October 29, 2010 (UTC)

Ive heard a buzz on a bunch of Game Forums that Perception does nothing for accuracy. Someone even mentioned comparing a lvl 1 perception/100 gun vs a lvl 10 perception/100 gun and noticed no difference. Though this is just me taking their word for it. Im guessing perception does something to VATS accuracy? I noticed in my playthrough that even though I had maxed gun, my VATS couldn't hit anything within 20 metres of me.

70.79.230.199 22:24, October 30, 2010 (UTC)

I would trust that comparison more if they had, say 50 gun skill. In Bethesda's skill system extreme high and low numbers tend to break the rules.67.149.196.9 09:21, November 12, 2010 (UTC)

  • I had a perception of two and then on my second character, 1, and have no accuracy problems at all. In the older games it was useful but...now it is pretty useless. Even with that low of a perception I still see hostiles on my compass before they are close enough to notice me. --Pongsifu 04:29, November 23, 2010 (UTC)

It's easy to test for yourself in VATS, using a weapon that falls under the Guns category, without maxed perception, target a stationary NPC in VATS. Exit VATS without attacking, take some Mentats then target the same enemy again. When I tested this I noted that the accuracy did not change at all after taking Mentats. --124.169.74.44 11:28, July 24, 2012 (UTC)

Seeing Longer Distances?[]

Ok so the page says Perception lets you see objects at farther distances but after a quick test I have found no difference in noticing people from farther ranges. Tested with 7 Perception person showed up the same point as with 10 Perception. The extra Perception was added with hat and glasses. --1stRecon 04:25, November 23, 2010 (UTC)

It means the red "hostile" markers on your compass will show up for hostiles further away --Pongsifu 04:29, November 23, 2010 (UTC)

I find perception invaluable[]

I always max perception, (easy with with 4 eyes, implate, and a hat, maybe an intensive training). It's extremely useful for sniper builds. If you can't spot an enemy from afar, then your long range weapon is useless. With 10 perception, you can have enemy on your radar that won't even get drawn unless you zoom in with scope.

I don't like keeping companions around as they screwed up your combat plans and make the game too easy, so no help from ED-E, 10 perception all the way. (7+1 str, 6+4 perception, 6+1 endurance, 4 int, 1 cha, 7+1 agility, 9+1 luck)Dvd777 07:30, November 23, 2010 (UTC)

What platform are you playing on? With graphics maxed on PC I can see enemies drawn in the distance without zooming in so far away that if I zoom in I can only hit them when standing still with a sniper rifle because it is just too hard to hit them at that distance if they're moving. What I'm saying is, they should be drawn in. --Pongsifu 07:49, November 23, 2010 (UTC)

Perception is Usless in FNV?[]

Ok hear me out so aside from the obvious early game stat boost that can be made up later on and like 3 speech options that require perception the only thing this dose is dictate when the red markers appear right? But the ED-E's perk boosts the red markers already so it basically balances it out right? I mean you don't have to even bring ED-E along you can just have him wait and its like having a container where ever you want. So unless your absolutely set on having Rex as a companion there's really no need for this skill at all. Or dose it do something else? --1stRecon 01:36, December 1, 2010 (UTC)

I find it useless with or without ED-E. --Pongsifu 04:00, December 26, 2010 (UTC)

Increased VATS distance?[]

Does Perception increase the distance that can be used for VATS? --The Bart 12:10, December 6, 2010 (UTC)

10 Perception, 1 Perception[]

I added the two quotes Doc Mitchell gives you for having 10 or 1 Perception in the notes section. --CptMuddles 16:35, January 3, 2011 (UTC)

New Vegas Perception Is Useless[]

Honestly is this stat completely useless? Ed-E's perk doesn't help. I just tested and it doesn't affect VATS accuracy nor does increase the range which you can use VATS.

Bug?

dont know how it happened but my perception has been lowered drastically. I am 100% healthy, no injuries and no addictions. Any way to fix this bug?

Editing NV PE entry[]

I edited the PE NV entry regarding the attribute affecting VATS. There isn't a single reference in GECK regarding the use of the attribute for calculating weapon damage, spread, critical chance or wahtsoever.

According to the Bethsoft GECK page:

The gun spread formula: Spread = PerkModifiers(IronSightsBonus * CrouchBonus * (ConditionPenalty + SkillBonus) * (WalkPenalty + RunPenalty) + ArmPenalty)

The weapon damage formula: Gun Damage = (PerkModifiers(BaseWeaponDamage * DamageMultiplier * GunConditionPenalty * SkillBonus) + CriticalDamageBonus) - DamageAbsorbedByArmor

The VATS formula, Critical Chance/Hit, all guns spread conditions and all weapon damage conditions also don't use a single entry depending of PE. How come Perception influence in VATS? Also, none of the condition penalty, gun condition penalty and walk/run penalty list PE as an effect.

What PE affects is enemy detection and this will affect combat mode. That's it. So I ask again, where in hell PE affect VATS? Brfritos 21:27, July 4, 2011 (UTC)

New Vegas: Losing a point of Perception bug?[]

I'm playing New Vegas, and when I look at my S.P.E.C.I.A.L. Stats, it says I have 6 perception with a (-) next to it. I am supposed to have 7. When I go to 'EFF' under my Status, there is nothing there that says -1 Perception. I don't have rad poisoning, I don't have any addictions, I'm not wearing any perception-loss clothing, and I don't have any perks that rob me of Perception under certain conditions. What is happening, and how do I fix it? Tocinoman 02:38, January 15, 2012 (UTC)

Not sure, but just in case you should remove all your equipment, sleep, go to a doctor to get your limbs and radiation poisoning looked at, and then check it again. Sometimes I find that my stats go down and I have no idea why, and only ages later do I realise that it's something obscure. 114.77.77.5 02:40, January 15, 2012 (UTC)

I've noticed that as well. I think it has something to do with the Hoarder trait and Boone's Beret. I chose the trait a second time when asked if I wanted to change them. Everything was fine until after I finished with Novac's main quests (I have a save file that's a few minutes prior of reaching Novac with no negative Perception).

I've noticed something similar as well. With full health, no crippling, no poisoning, no radiation, no companions no any kind of equipment, and having nothing else that could decrease perception, I should have 8. But recently I noticed that it got decreased to 1 with a "(-)". I have no idea what or when happened, and how to fix it. I've taken antivenoms, fixers, I've been to doctors, was sleeping a lot but nothing helped.

Description for Perception[]

Doesn't perception affect Lockpick, Energy Weapons and Explosives in FNV? The section for FNV is missing what skills it affects, whereas for example Strength's description for FNV shows "Strength in New Vegas modifies Melee damage, Carry Weight, Melee Weapons skill and which weapons you're strong enough to use." The description for FNV new vegas doesnt mention anything to do with skills...

Fallout 4 Perception Bug[]


I am faced with a very bothersome issue that I cannot seem to find any source of or fix to regarding Perception on Fallout 4 playing on the revamped survival mode. I have my Perception at rank 10 and have picked up the Perception Bobblehead after reaching rank ten so it should be at a natural 11 without any modifiers from chems, food, clothing, etc. I had explicitly waited until I reached rank ten before picking up the bobblehead so I know I should be rank 11. However this is not the issue. The issue I am having is what I saw when checked my Special Stats; I found that my perception reads: (-)2. I an not sick, hungry, thirsty or hurt in any way. I have no active or passive effects and I have no other perks. I am going to go insane if this keeps up. I am playing one the Xbox One. Does anyone have any idea or fix? Is it just displaying that I have my Perception at (-)2 but it is actually registered as 11? Or is it even worse with it being at (-)2 despite there being no modifiers?

Perception Bug PC Console Fix[]

I found myself dealing with the perception bug and was endlessly annoyed by it. So I figured I'd try to figure out what happened. It was a stingwing attack and I took Med-X. So the simplest solution would be to check my poison resist was 0 with the console, jack it to 250, get stung by a stingwing, and reduce my poison resist to 0. Problem solved. Even under getvalueinfo it now reads Temp as 0.00.

I don't feel like figuring out all the nice typefonts and formatting necessary to add it, but this is the series of steps

Player.modav poisonresist 250 Player.placeatme 5FBB3 Get stung and immediately reopen the console Player.modav poisonresist -250

After that, provided this reversal is exact (same poison resist as when the event occurred, in my case it was just med-x so 250 was right), then getvalueinfo perception will now read Temp: 0.00

-Edit- Also if the issue is more complicated and also is associated with the Temp Modifier Value one can always try different poison resist values. There is probably a function based on the stingwing poison damage (which I believe is 5), the poison resist before/after and during the poison, and the exact Temporary Perception Modifier on the character. Mine just happened to be simply 0 before and 250 during, leading to a Temp of -4.40. Tried removing a poisoner's during an attack and got a -.78 (I believe). The spherical chickens in a vacuum solution above will actually probably work for most PC players. And if you were on survival difficulty you just need to reenable ot after doing this with the console.

FO4 and Perception > 10[]

I've been trying to work out whether or not it's worth saving the Bobblehead to push PER to 11, especially with the note on the VANS page claiming that the bonus from VANS 2 has no effect on accuracy (which makes it totally pointless if true).

Just started a new game and found a sleeping Radstag, so here are some VATS numbers from a perk-free char working with an nice immobile target:

  • PER 5, 23% torso hit chance
  • PER 10, 28% torso hit chance
  • PER 15, 34% torso hit chance
  • PER 20, 39% torso hit chance
  • PER 25, 44% torso hit chance

The increases - bear in mind, this is with a 10mm and I'm not right on top of the doe, because if she bolts I'd have to start over - are linear enough that the discrepancy can be attributed to rounding error or environmental factors etc. So "10% per PER" is very credible, but it's also somewhat misleading. 10% per PER as a MAX chance with a cap of 95% only "really" matters if you're actually getting that max chance, which means being at melee range or having additional perks in play.

  • PER 12, 30% hit chance.
  • PER 10, VANS 2, 30% hit chance.

So the VANS page is incorrect.

TL;DR Yes, PER > 10 absolutely has an effect, and if you're a VATS-heavy player you should save the Bobblehead until you've already pushed PER to 10 via Intense Training, AND wear +PER gear, AND take VANS 2. Every point makes a difference, no matter where it's from or how high you push it. 66.214.99.253 04:12, May 2, 2020 (UTC)


Snuck up on the doe as much as I dared, since the better the condtions the clearer the deltas are.

  • PER 5, 66%
  • PER 10, 81%
  • PER 15, 95%
  • PER 10, VANS 2, 87%
  • PER 12, 87%

So yeah, VANS 2 is absolutely equivalent to +2 PER as far as VATS goes. There's no "special case" to it that stops it from having an effect there (as you'd expect, since that would make it worthless, but you can never tell with Bethesda :P). 66.214.99.253 04:25, May 2, 2020 (UTC)
