In Far Cry 2, when I set it to "Optimal" in the display settings, everything goes to the lowest setting. At that setting the fps wavers between 72 - 128, and when I use the "Very High" setting I get between 20 and 47 FPS. I have AA at 2x. The resolution doesn't seem to make a difference: it's the same at 1920 * 1080 as it is at 1440 * 900.
In Assassin's Creed, at 1920 * 1080, 1/3 Multisampling and 4/4 graphic quality I get between 38 and 53 FPS.
Aren't these frame rates low for the system? What could be causing it?
I have already installed the latest Nvidia drivers.
