Hey guys, I recently noticed that OpenGL works very bad with the nVidia driver's threaded optimization option. Firstly, I noticed SpaceEngine (OpenGL) worked perfectly with it off. Then I tried the same with Minecraft (OpenGL), same thing, worked perfectly. So this leads me to the theory that, OpenGL sucks with Threaded Optimization enabled. The problem with it was, it lead to stuttering while moving camera. Last but not the least, SpaceEngine rocks! Cheers .
