Forgive me but I've been looking a lot for solutions in the past, recently had an update of windows and NVIDIA on the same day, hoped it was the solution of my prayers.... Still no idea what it helped that update
.
There might be some answers now, I looked a little around and just got lost because of all issues with 8.1 and nvidia, I didn't find any so that's why i just begged forgiveness.
I got the windows 8.1, NVIDIA GeForce GT 640, new desktop pc from just perhaps a month before the update to 8.1 and suddenly 2 of my most favourite games crash after a couple minutes. (civilizationV and stronghold3)
The previous time I went looking for solutions I found one that made the graphics better but it still crashes. Someone, I think on this site, posted to turn of stereoscopic 3D from the config screen.
It's still turned off, I tried a couple compatibility modes and those don't even let me start the game!
Anyone got some advice, help or links plz?
