I've found that occasionally during the game, action and effect become desynced. This isn't lag as in actions on screen being delayed slightly due to low framerate or actual input being delayed - it's where the result of an action will lag a few seconds behind the action itself.

I've noticed this with equiping spells with hotkeys, casting spells, attacks and most blatantly with archery. Basically I can draw the bow back, release, see the release animation on the bow, and then wait a few seconds before the arrow launches and hits the enemy. WIth spells, it looks like the spell hits the enemy, but the damage and hit graphic will occur a few seconds later.

It happens only occasionally but when it happens it's VERY noticeable, not to mention very frustrating when a well timed arrow misses by a few seconds. Other than this issue the game runs very well. I have an almost brand new PC with the following:

Intel i5-2500k @ 3.3Ghz
8GB DDR RAM
AMD HD 6950 2GB
Windows Premium 64bit

I've turned v-sync off and am using a frame rate limiter to keep the framerate under 60 fps.

Has anyone else experienced this? I've googled extensively and it seems like no-one's really having this issue.

You're checking your framerate when this occurs?

My framerate is very consistent at 60 or thereabouts everywhere except in cities. It also doesn't go over 60 because I've capped it (heard of physics going wonky above 60fps).

It's definately not framerate related.

It tends to happen in dungeons while sneak shotting enemies. After 1 or 2 shots it goes back to normal. Its very irritating not knowing when your shots are going to count.

I also observe delays in equipping spells using numbered hotkeys - the hand comes up but often the spell effect takes a good 5 secods to appear. Casting the spell before this happens also has no effect. This only happens in dungeons and can be avoided by switching through favourites menu.

There's also miscelaneous delays in item models showing up while shopping or cooking. Not sure if any of that is related to the same issue.

Anyone else getting any of this? Just want to see if it's a widespread issue and whether people are just not bothered by it?

I′ve got the same problems as you with the same PC setup and the new Catalyst Preview driver. Sine the newest patch it seems as if I have severe mouse lags, no ini tweaks are helping. I don′t know what they screwed up now since it′s only after the new patch but hey, it′s gamesas :/

Nothing's really changed for me with the latest patch - I've had this problem since 1.3 and probably 1.2... i don't recall.

Did u also try and play it on low video settings? Try to disable the frame limiter as well to see if u get different results.

turning v-sync on results in a very stuttery mouselook for me, so it's always been off. Turning the frame limiter off results in problems associated with high framerates so it's not really playble like that either.

I have tried limiting the framerate to 30, 50 and 60fps and that hasn't made a difference.

I will see if it still happens on lowest graphics settings and/or vsync on just to isolate the cause.

Justinian, I'm very curious to hear what you find. I'm having the same exact issue. Not sure if I have had it since release, but it has become very apparent lately - with bow. Your description of the issue is spot on.

I'm also running with vsync off in the ini files, and using a fps limiter at 60fps. If I figure anything out, I will report back.

FWIW, i'm using 2x Nvidia GTX 470s in SLI.

Update: Just practiced behind the Companions building in Whiterun and couldn't get it to duplicate. Just a slight delay on one shot, but nothing major.

Similar thread from Nov here: http://www.gamesas.com/topic/1275049-arrow-delay-glitch/page__p__19319867__hl__bow%20delay__fromsearch__1#entry19319867

I'm not surpirsed there are other people experiencing this as I've just found the cause!

It turns out that whenever I have my frame rate limiter on, these desync issues pop up. I tried entering a dungeon multiple times with:

vsync on

vsync off

vsync off & framerate limiter on (framerate limiter turns vsync off anyway)

Every time I entered the dungeon with the framerate limited, My first 1 or 2 shots with the bow would be delayed by a few good seconds.

This is a bit of dilemma though - as playing with both vsync on and vsync off have their issues for most people. When the framerate limiter is brought into the equation, to fix those issues, these dysync and lag issues appear.

The only ways this is going to be resolved is either for Bethesda to fix their vsync issues or to find a framerate limiter that somehow doesn't do this. Does anyone use a different framerate limiter to "skyrim FPS_Limiter-34-V1-01"?

I use the one as part of iCCC ENB - http://www.skyrimnexus.com/downloads/file.php?id=180

OK, had a play around with another framerate limiter called Dxtory and the same lag happens, despite Dxtory allowing vsync to stay on.

CONCLUSION: In order to get around the annoying mouselook stutter or mouse lag related issues, there are two things you should never do:

- turn off v-sync (causes physics glitches)

- try to make up for turning v-sync off by capping the framerate at 60fps (or any other fps for that matter) as this will cause gameplay syncing issues.

I did some more research and discovered people have alternatively been running Skyrim in a window to combat vsync. Turns out a nice little program called Simple Borderless Windows http://www.skyrimnexus.com/downloads/file.php?id=4 allows you to remove the borders of the window to simulate playing in full screen. I've played Skyrim like this for a while and it's definately the perfect solution to avoid all glitches while rectifying mouselook issues.

Hope this helps people out

BTW: it seems like all other lag related issues such as grass sometime failing to load until I'm on top of it, and object models taking a long time to load in menus, have also been fixed with keeping vsync on.

During hectic fights I occasionally notice either a delay, or worse a simple refusal to activate, of the Shout. I assumed this to be script-lag, I sometimes see it in other games too (ArmA2 for example). Only FPS "helper" I use is turning vsync off. Original game as installed, no patches.

Turning OFF Vsync will increase delays because threads need it to sync properly.

Not sure if it's a fluke, but I just went to a dungeon and had no issues. Noticed this thread, where there's a skyrim.ini memory tweak I had enabled that was causing other delay issues for the OP: http://www.gamesas.com/topic/1322205-1310-time-to-revisit-some-ini-tweaks/

I still have FPS limiter on and vsync off. Will keep testing, but seems to be ok so far, but could be just an anomaly.

Bottom line, if you have this in skyrim.ini under [Papyrus], remove it:

[Papyrus]
iMaxAllocatedMemoryBytes=2000000000

So I think we can all conclude that the only way to play the game is with vsync on, and the best way to play it with vsync on is to use Simple Borderless Windows. Pretty simple really.

Previously when I was using vsync off and framerate capped, enemies also tended to have extreme ragdoll physics after being killed. I was getting sick of corpses being flung 20 meters off and downloaded a "realistic death physics" mod. Turns out that playing with vsync on also gets rid of that issue too, so I've gotten rid of the mod

I don't think so. I've been using a border remover since 11/11/11 (using an autohotkey script) - and always had issues with vsync on.

Look at my previous post and see if that helps - not sure if you have any skyrim.ini tweaks.

So you had delays with vsync on? That's strange.

I haven't messed with any ini tweaks at all, so that can't be the cause of the glitches for me.

The issue I had with vsync on is the poor/inconsistent fps - and it jumping around causing choppy gameplay. I'll give it shot back on, but the fps limiter really improved the smoothness of the game for me.

Curious, I've heard enabling Triple Buffering with vsync can help a bit too. You may want to give that a whirl (I will, when testing).

I just read above that you're running in SLI. Perhaps that's why running it in a window doesn't solve your jitter issue? You're the first I've heard who hasn't solved their mouselag/stutter issues by running in a window. It apparently also stopped crashes for some people too (and this was before the LAA patch).

I shouldn't have said "stutters" - it's more framerate dips. Disabling vsync and capping fps kept my frames 50+ 90% of the time. Now, it drops here and there and slows mouse input.

Ok. I think I have vsync working properly now. The key for me was to disable Skyrim vsync. I removed any presence of "ipresentinterval" in skyrim.ini or skyrimprefs.ini. Then I went to nvidia control panel and forced vsync there.

So far, consistent 60fps - no frame drops, mouse lag or anything -- so far.

Edit: Bah, indoors was ok, with a few dips, but outdoors was 40-50 fps and rapid spikes back and forth. I'm going back to vsync off - much better overall experience.

Still sounds like SLI issues perhaps? Have you tried disabling one of your cards?

Also, would be interested to know if you can confirm weird sync issues with vsync off?

I'm finding that running borderless window solves all issues for me, but still curious about whether others are running into these delay issues (I presume a large proportion of people are running vsync off and capped framerate).

same isue, with arrows AND spells, Playing the game with vsync on AND fps limited to 60 (no inputlag and smooth gameplay)
and it only happens indoors, but ive had occasions where it would happend outdoors

allright did a test:

game running without vsync and without FPS limiter (bandicam, dxtory, etc etc) = No problems, no delays

game running with Vsync and without FPS limiter (bandicam, dxtory, etc etc) = No problems, no delays

game running without Vsync and with FPS limiter (bandicam, dxtory, etc etc) = Delays and problems

game running with Vsync and with FPS limiter (bandicam, dxtory, etc etc) = Delays and problems

seems FPS limiters are the cause, well not the actual cause, but the way the game is Programmed

edit: i play allmost any game with vsync and FPS limiters and this is the first game making a hash out of it
