Alright,so,I have multiple problems with this game but long story short I'm using the 1.02 version of the game which is not that great but at least it doesn't stutter like the newest version with all the expansions installed.Now,the problem I had is that the game freezes and then I get the error that the Nvidia driver stopped working,sometimes it says that the game has been restricted from using the graphics card or something similar like that.Anyways,I fixed that problem by increasing the voltage of my graphics card,but now it came back,and sometimes my computer crashes when I play this game,the computer just freezes completely and restarts.I play lots of games on this computer and the only game that I have problems with is Witcher 3.
My nvidia driver version is 368.39
If anyone can help that would be great.

Sorry for spelling or grammar mistakes if there were any,I really want to fix this as fast as possible.

Is a 570 compatible with W3? Probably wrong, but not convinced that the architecture is new enough?

From systemrequirementslab.com, W3 needs:
Nvidia GPU GeForce GTX 660 / AMD GPU Radeon HD 7870 Min GPU

- I know the 570 is as fast / faster than a 660, but maybe doesn't support the features / instruction set that later arch's do?

I don't know,but GeForce Experience recommends high-ultra settings on this graphics card.

You're system just meets the minimum requirements - except for ram. I'm not even certain that adding ram will fix the issue, but certainly won't hurt. Also what settings? Maybe turning down some of the settings.

I'm going to buy a 4gb ram stick in a few days,don't think it will fix the issue with 1.02 but it should fix the stuttering on the newest version with all the expansions.My settings are on the high preset,however i changed 3 settings,those are:
Number of backgroud characters: Medium,
Hairworks: Off,
Foliage visibility range: Medium

EDIT: Forgot to mention I play on Windowed mode,the resolution is 1280x768 (I can run it on my native resolution fullscreen on these settings with no problem as well,but I got used to playing all my games in windowed mode)

I had to roll back the NVIDIA drivers,the game works fine now.
