Thanks. I would have other 3 question to do to complete the everything. To thing they serve the three options: 1) Off Screen Drawing 2)frameBuffer effect 3)FrameBuffer Upload and to how much I must plan her to have the maximum one some performances (1,2,3,ecc)?
which compatibility settings will give you the best performance? it depends on the game and your hardware. having it so all framebuffer effects are emulated can put a strain on lower-end hardware but the specs you posted should handle them fine. the other factor is the games you want to play, some perform better with certain settings and some perform worse.
