Hi all, I recently acquired an Acer 6920 (GeForce 9500M GS graphics) laptop with Windows Vista; upgraded it to Windows 7 and runs great for its age. However I've noticed a problem with the graphics playing games. The 3D effects don't appear to render correctly and produces like a jagged effect and doesn't show things like buildings where there should be. I've got the latest driver from Nvidia installed but seems to make no difference. Problem exists on old games like Midtown Madness 2 as well newer games like Sims 3 so it's nothing to do with the graphics card not being good enough. Anyone know what might work to fix this? Thanks.
