NVIDIA 285.27 beta drivers, OpenGL 4.2 issues

[BlackDaemon]

I decided to move this to dedicated thread, so, if anyone experienced such issues, like below - switch to older drivers, please.

(only "Enable saving GE screen to Textures instead of Memory" affected)
- after loading any game appears some cached pictures instead of blackscreen

("Use vertex cache" + "Use shaders" + "Enable VAO" + "Enable saving GE screen to Textures instead of Memory" settings combination affected)
- after switching some games (for example, first time i run some game N, then reload JPCSP and load god of war) also some strange artifacts appear
