The graphics card idles while playing any version of Minecraft. It does run when I start Minecraft but when I am in the main menu or in a world the graphics card idles. I does not matter if it is modded or not. I do not know of any other OpenGL games that I play. I usually only play modded Minecraft and World of Tanks on this PC. Never had any massive framerate issues with any games other than Minecraft. I am not too sure but 100 FPS in Vanilla Minecraft seems kind of low with my setup. Maybe that is why my modded Minecraft FPS is so low.
