Performance issue on GTX 1080?

[kg7241]

So i tried cranking up my supersampling by a little and then my weapons start stuttering like it did with fallout then i turn that low again and in game settings i can only play on medium because if i turn it up to high my game starts lagging and mods just kills the performace of the game i have a regular GTX 1080 i7-7700k and 16 gb of ram... Whats up with this? people with lower specs can run the game on high with good mods, why cant i? it lags the most when im around water or waterfalls or the watchtower where you fight your firdt dragon

My guide has a step by step how to with pictures if that'd help. Try scaling everything back to 100% first (and in game all the way to the left). If that doesn't help may I ask if your turning using a thumbstick, or by turning in real life as there is a stutter fix if your using the thumbstick to turn left and right. With a 1080 keep dynamic resolution off, you really shouldn't need it.

Another thing you can do is download the latest drivers for your gpu and when installing select clean install.

Lastly, are you using an Oculus Rift? or a Vive? or a Windows Headset?

Hey Gabi. Nice guide with pictures to how any newcomers where to go to set the super sampling. However, you have missed out the global super sampling Steam applies under the "Video" tab. By default on a 1080 this will already be set to 170%. The application tab is to add additional multiplier factor to this number on a per-game basis, then the in-game one multiplies in again.

To OP: With a 1080, you should be able to run this game with reasonably high levels of super sampling but just to rule out you're not cranking up too many of the various sliders available, I'd recommend the trying the following to turn all the SS down. After you've checked the game runs smooth again, you can begin to dial ONE of the available sliders. There really is diminishing returns with the SS after a certain level but as you increase the sliders, the load on your GPU can become extremely taxing.

1.In the Steam VR desktop widget(see Gabi's guide if you can't find) under "Video" check the box for "manual override" and turn this down (should be auto set to 170% on a 1080) to 100%.

2.Under "Applications" check that Skyrim VR is set at 100%.

3. Open Skyrim VR and turn the in-game super sampling slider all the way down.

4. Turn off Dynamic Resolution.

5. Turn TXAA on or off depending on your preference of blur vs jaggies (this can be tweaked later)

You are now running the game at native resolution for Vive. If you have an Oculus or WMR you will also have to turn down their specific super sampling/rendering options in the tray/tools provided by them.

6. Check that your game is now running smoothly - Don't worry too much about the graphics not looking great quite yet - we're only interested in ruling out stuff to do with too much super sampling at the moment. If game runs smooth then do step 7, if it's still really bad then look to the end for suggestions on what to try investigating next.

7. Close the game (super sampling changes won't take effect without reloading) and go back and start to dial up the global super sampling settings listed in point 1. Try 150% then go back into game and check again how it is running. If all is well, exit out again and turn this up some more. You probably should be able to reach 200% as long as it is just this one slider you're changing.

At each stage of increasing it, be sure to check you can actually really notice any difference in the graphics as otherwise you'll be burning GPU power for no reason.


If none of this is helping then your problem isn't with the vanilla game and must be mod or rig related. I've installed a few mods that have just killed off my frame rate and I have a 1080ti! un-installation of said mods remedied all my troubles. You can monitor things like CPU/GPU loads and temperatures to ensure it's not something up with your rig.

If you post your mod list, I'll look over it and see if I spot anything that was giving me hassle.

Good luck.

So one good thing that happened is I turned off the DPI and it made lag free when I put the slider all that way to where you told me to put them but now everything is blurry and when I turn up the supersampling to around 190 I start lagging a bit and that's with medium settings in the game

Do you know exactly what resolustion scaling you are running at and what your FPS is? If you don't know that, you will have a hard time figuring out the issue.

Try starting out with disabling all your mods for now and then figure out what your resolution scaling is in game.

So I was running It at the default resolution and the frames ratio was about at a 29

DSR factors affect VR performance? I always have that on....

It is my understanding that DSR is kind of similar to super sampling as it renders the image at a higher resolution, then downsamples it to whatever the monitor/headset resolution is. I know it was causing issues with Fallout4VR for some folks but haven't seen anything here about it.

100% zero harm in turning it off for VR stuff as think it was designed to be for pancake games as an aliasing solution.

Yeah, it's pretty much exactly the same thing. But you can consider it inert for VR, I would think. Just having it turned on in Nvidia control panel won't apply it to the game. So for instance, if you are playing a game on your monitor, you have to select the DSR resolution in the game, otherwise it won't do anything. In VR, I have to assume that DSR is just going to default to the resolution of the VR headset, just like it would in a non-VR game.

I'm running SLI GTX 1080 Ti's and a 7700K. SLI does improve performance, but it doesn't function like it should. I'm running 1.9x SS in the Rift Debug tool and all other settings maxed in game including SS and my game runs perfect everywhere. I'm over clocked too of course.

1.9 in Oculus seems like extreme overkill to me. Did you check to see the resolution scaling that actually comes out to in Skyrim VR? I'm using 1.3 in Oculus and the SS slider half way in game Skyrim VR and that results in 200% resolution scaling in Skyrim VR. Setting Oculus rez scaling and setting it in Steam VR or Skyrim VR will give a multiplier effect.

I have a GTX 1080 also with i7 4700k and 16gb ram, i also had instant lag as soon as i increased SS ingame no matter what settings i used. My Advanced SS was set to 184% with my 1080.
My solution was to set graphics at high and ingame SS off , then i set my multiplier in Steam VR Applications setting for Skyrim VR at 130%. everything is crystal clear now with over 30 mods including 2017 Textures, you might be able to set it higher depending on your cpu and ram but this worked for me and the game looks great.

What was your video Manual override to?

[Aska]

@OP do you have OpenVR advanced settings installed ?

yep installed it today

Set SteamVR Supersampling @ 200% for SkyrimVR

Before launching the game , set OpenVR-AdvancedSettings Application Supersampling @ 1.0
Start the game

In SkyrimVR , set the in-game SS @ 0% (slider max to the left) and increase OpenVR SS from 1.0 to 5.0

This didn't do anything :/

kg7241, are you still getting controller stutter/lag? If so, did you try the Havok physics fix?
https://steamcommunity.com/app/611670/discussions/0/1696043806572733778/
Any effect?

I was kinda confused on that one on which ini to put it but I ended up putting it in skyrimprefs but felt no difference:/

update your video drivers, ive seen a lot of ppl on the VR facebook page having these problems, they were fixed by updating your driver.
I have a ton of mods and my settings cranked up with no problems (1080ti)

Ive updated my graphics driver to the current one on nvidia but still runs like crap
