Enable GPU scheduling

[SkyE911]

I was having some major crashing on DX12, and some odd visual errors. After enabling GPU scheduling Witcher 3 now works on ultra + now. RT and RT+ is still bad, I hope this helps some people.

Don't have that option on my PC. Using a 6700XT. Game runs fine and everything without it, wonder what card you have that gives you the option to use it

It's only supported by nvida GPUs i'm pretty sure

I'm fairly well-versed in pc hardware stuff but never heard of GPU scheduling, was wondering if it's only something for older GPUs or if it's still a thing for new models as well. Then again, I've always used AMD cards (old one was a 580) so I probably never had a reason to look it up lol

It is a somewhat "new" Windows feature.

Its kinda new. Its meant to offload some of the tasks of the CPU to the GPU so that your CPU won't bottleneck as much. For the witcher 3 it can help because of the terrible CPU utilization with this new update, though it can cause issues due to numerous factors so its best to try it.

Should be enabled by default on Windows 11, in my case, it was already toggled on.

For those wondering where to find this setting in Windows 11:

Windows Settings --> System --> Display --> Graphics --> Change Default Graphics Settings

'hardware accelerated gpu scheduling' will be the first option and the 2nd will be 'variable refresh rate' both of which were enabled by default for me on my 12700k / 3080ti / 144hz gsync monitor

Thanks you (and everyone else) for the info about it :)

It sometimes described as HAGS aswell.
Gives a small performance boost in those games that can take advantage from it.
But its not always working in all games including "full screen optimization", so keeping an eye on these settings is never wrong.

Steam and browsers usually have it too but for desktop applications instead of 3D apps in this case.

Just a quick reminder, if you enable this it does sometimes give horrid performance afterwards. GTA 5 gets hit massively by this being enabled, so just make sure to disable it first when troubleshooting bad performance in a game.

Don't forget to restart the game after bigger changes in settings been made like these mentioned here - as with others like vsync etc.
