I just bought a new computer and the first time I started it I set the resolution to highest my moniter would support (1024x768) I tested some games to see how well they would run and they worked fine. After rebooting (windows updates) it looks like the resolution is 800x600 even though display settings says 1024x768 It also plays Assassins creed windowed for some reason but I think it has to do with the resolution problom as there are no window options for assassins creed. I have a NVIDIA GeForce 9600GT with windows vista.
