Mouse slowdown when looking around, yet I still have high FPS.

[FinnenH4wke]

Hey,

 

I have extremely weird problem. I finally finished modding my Skyrim - playing with some texture packs (I optimized them to 1024 res) and Grim and Somber ENB (performance version with ENB .254). The thing is that I'm getting great FPS (mostly around 60 with very occasional drop to 50). HOWEVER I'm encountering major slowdowns when looking around with my mouse. My FPS stays above 50 yet when I look around there are places where I feel like something's holding my mouse. It's getting slower in these places, like moving in mud or glue :tongue: It's very hard to explain, I haven't encounered such a thing in any game before.

 

In most cases it happens when I'm looking at the light sources. I have ELFX installed but I uninstalled it and tried playing without it - exactly the same thing happens. It's very noticable in Whiterun's inn - Bannered Mare. When I go behind Hulda and look at the fire inside, there's a major slowdown. I move around and whenever there's fire on my screen I instantly feel as if something was holding back my mouse. Yet, FPS stays above 50 all the time (though it feels like 25-30 in these few seconds). It happens in Bannered Mare but it's not limited to it - it's also noticable when standing near the well in Whiterun and looking in the direction of the tree and Dragonsreach. I also felt it quite hard when I was walking outside of Whiterun. Do you guys have any idea what might be causing this? This is the most bizarre thing I have ever encountered in Skyrim. I would understand it if FPS was going down to 30 or less, but having such a gooey feeling when running at 50+?

I finally solved the issue. There are two ways to do that - using FPS limiter or running the game in borderless window. I don't like FPS limiter because it limits your WHOLE game to particular FPS. Running the game in borderless window fixes the issue aswell yet you don't have to limit your FPS. The best way to apply borderless window fix is by using mod called OneTweak. It's a SKSE file, it works out-of-box. Just install by adding the plugin file to SKSE folder and you're done. If your ENB is giving you FPS drops then obviously you will still have them (this mod is not supposed to increase your performance), however they won't come with this weird, unpleasant mouse stopping glitch (this seems to stop when the game is running in borderless window).

2 things

 

Did you turn off Mouse acceleration?

 

Other than that I had an issue with my other nice mouse a gaming mouse, put my regular mouse in and my problems went away.

Actually yes, I did turn it off today but only because I was looking for a solution to this problem. It might be a mouse problem, however I'm not encountering similiar problems in Counter-Strike or any other game. However I think I might have just fixed this weird glitch. Turns out it might be a problem with 60 fps. I read just a few minutes ago that Skyrim has a problematic engine and weird things appear when it goes to 60/61. Even though I have VSync enabled (obviously, without it game physics go rampart) my FPS still sometimes jumped to 61/62. I enabled ENB Config screen and set FPS Limit to... 58. And you know what? I felt the difference instantly. I was still getting some smaller slowdowns when I was looking at bigger distances where FPS drop would be slightly bigger (for example to 50 or 48)...

 

... which led me to believe in one thing. Apparently my Skyrim has a problem with maintaining FPS. Whenever there's an FPS drop, even the slightest one (like 2-3 fps) I encounter this weird slowdown. So I checked what was the lowest FPS I get and I think it's around 45 in the heaviest places (happens very rarely, usually I get 49/50+). So I set my FPS limit to 48 in order to maintain 99% stable FPS. And the problem is gone, completely. This might be a problem with VSync, I heard that Skyrim's built-in Vsync is terrible and it's a good idea to disable it (along with ENB's vsync) and force it through Nvidia Control Panel. I might try it.

 

tl;dr: Setting FPS limit to 48 fixed the issue in 99%. No more weird slowdowns.

When you use Vsync in Nvidia....Try with Adaptive 1/2 Refresh rate....Liquid smooth.

 

On the fire thing...if you are still seeing that ...in the ENB config...try turning on and off ...

EnableSoftParticles=true

EnableParticleLights=true

EnableDetailedShadow=true

EnableSubSurfaceScattering=true

OR any others..forgot which one was giving me the slowdown looking at fire...also did you get the "Skyrim particle patch for ENB" from ENBdev.com?

[FinnenH4wke]

Thanks, I'll check these settings and try to tweak them. FPS limiter fixes it in some places but not everwhere - depending on ENB and actual FPS it's more or less still there.

 

Apparently it's a problem with ENB - when I disable the ENB with Shift+F12 the problem still persists, however when I delete the ENB completely from Skyrim folder and run the game, then it's all good - no problems at all. I found the topic on ENBDev website with same problem - http://enbseries.enbdev.com/forum/viewtopic.php?f=20&t=489. I guess I simply hadn't noticed it before, until now.

 

Camaro, as for the Vsync in Nvidia. When I set it do adaptive (normal) then I have smooth gameplay, however setting it 1/2 refresh rate cause massive slowdowns. It feels like moving a hand in the water. My setup is i5-4440, 8gb ram, gtx 660. Well, the other easy fix for that is actually... playing on a gamepad :wink: I don't feel the slowdowns so much when moving around on analog sticks.

 

I'll do more tests today when I get back to home from work. But from what I've seen the problem is with ENB itself having glitches with different FPS. Locking it to a stable number seems to be the best way to fix it - so I think I'll tweak my ENB to have as stable as possible FPS without any FPS drops and then lock the FPS to stable number. As for the ENB Particle Patch - I don't have it from ENBDev however I have some Data folder installed from The Grim and Somber ENB profile. I think these particle patches are included into that package.

I solved the issue, the remedy for mouse lag with ENB is in the 1st post.
