[Skyrim] Mouse lag. Horrible, horrible mouse lag.

[Santr]

I've read other threads here on this, but nothing I've found helped.

 

 

1) This isn't an FPS issue. FPS never drops below 40 even in combat and usually hovers around 50.

 

2) There is no difference in the amount of lag between playing fullscreen or in a borderless fullscreen window (ENBoost).

 

3) As far as I can tell, I've followed STEP settings for INI files, but here they are, just in case:[spoiler=Skyrim.ini]

My system has 8GB of RAM and my AMD video card has 4GB of VRAM. Memory numbers in enblocal.ini are ones from 'AMD>4GB or greater' folder that comes with ENBoost.

 

4) I have no custom settings for Skyrim in the video driver (Catalyst 15.7 WHQL). I set everything through game's and ENB INIs.

 

5) I tried adding 'bMouseAcceleration=0' to [Controls] in SkyrimPrefs.ini in case of a miracle, but as STEP guide says, that setting did nothing.

 

6) Either of these settings removes lag completely (the difference is night and day), but also produces various and very obvious visual glitches everywhere (characters' eyes and fog disappearing/reappearing on camera turn, distant objects being visible through terrain, etc):

- iPresentInterval=0 in Skyrim.ini

- EnableVSync=false in enblocal.ini

^ I was wrong about #6. The glitches were caused by a mod, and I forgot all about it while tearing my hair out trying to solve this.

 

That's all I can think of right now. I would guess the problem lies in VSync, but it seems I can't disable it without issues, even if I wanted to (I wouldn't).

So, any ideas?

You can disable it and then limit the FPS to 59.9 either in the drivers or in enblocal.ini.

[Santr]

Success!

Turns out, the visual glitches I was experiencing weren't caused by disabling VSync/iPresentInterval, but by a mod (boy, do I feel dumb). 

And since Windows (7) Aero applies its own VSync on windowed Skyrim, there is no screen tearing... and no lag! Aww yisss!  ::

[Pretendeavor]

Hmm didn't know about the windowed vsync.. I always disable Aero hoping to get better performance
