Has anyone been able to run GK3 on windows 10 and what were the results??

I'm receiving major graphical corruption with GK3 on Windows 10.
Though admittedly, I'm running Intel Integrated graphics, which is know to cause issues with GK3. Though, on Win7&8 these corruption issues were fixed by setting the lighting to medium. With my upgrade to Windows 10, the game is suffering much worse corruption and is unchanged via in-game settings.

EDIT: I'm also receiving crashing as well...yeah, Windows 10 doesn't like GK3.

I'm thinking of just staying with windows 7 then.

I decided to test it today and it seems to work pretty fine for me under win 10, which is nice as the game constantly crashed on me under win 8.1 and the video sequences were choppy. Only thing I've noticed is that on scene load the animation playback seems to go a bit sluggish, but nothing major.

I also had to turn on the compatibility mode for the GK3.exe fro WinXP.

Yes, it very much is dependent on people's hardware & drivers...much moreso that on OS version. Older Intel GPUs, especially, are the pits for D3d 9 & earlier support--they do a lot in software--or rather they try to do it in software--and D3d games don't much like that...;) If you like gaming, I constantly advise people who ask, two things are a must:

1) Build a desktop
2) Use only an AMD or nVidia GPU

(I am well pleased with my R9 380 4GB card...!)
