I may have encounter a issue regarding to the white screen but it's not the game's fault it was my graphics card AMD. So when i change to NVDIA again everything is running smooooottthhhhddd with ultra and max resolution for high defined pictures hehehe
I'm running an AMD card (R9 270) and haven't had a single white screen issue with it. Not in this game or any other.
What was your AMD card, and which NVIDIA card did you switch to?
I seriously doubt your problem was solved by switching from AMD to NVIDIA.
Best case, driver issues.
Worst case, problem with the card itself that's unrelated to AMD/NVIDIA.
