Update: I rolled back to the previous drivers (355.98) and performance is smooth again.

The game used to run smoothly but ever since I updated the nVidia drivers and patched the game (I did both before I continued playing), I get framerate drops that weren't there before.

I play on a 1280x720 resolution with settings set by GeForce Experience minus hairworks, which I disabled. For the sake of troubleshooting I tried setting everything to the lowest settings. Performance was better but I still encountered some framerate drops. Up until very recently it worked smoothly with an almost constant 60 FPS.

My system:

AMD FX-8350
8 GB DDR3
GeForce GTX 960
990X mobo chipset
Windows 10

Does anyone else have the same problem? Is there anything that can be done about it?

EDIT: Forgot to mention that I'm using the Steam version.

Did you tweak files before installing the patch? Every time you update your game, all your tweaks are lost.

I didn't do any tweaks. Looks like the nVidia drivers caused the framerate drops and not the patch. I rolled back to the previous drivers (355.98) and performance is smooth again. Thanks for trying to help anyway.

Hi Doom972!

I had a problem too with the new patch and the framerate. I've found a solution and maybe it'll work for you.

Go to C:\GOG Games\The Witcher 3 Wild Hunt\bin\x64

Delete: d3d11.dll and dxgi.dll
Make a backup copy of these files

Can you please tell me how you reverted back to your previous driver? Geforce Experience won't give me the option to and I've tried manualy and that fail's also ??

I opened Device Manager, selected my GPU, and within the Driver tab I pressed "Roll Back Driver".

Thank you very helpfull :)
