Something Odd

Hello All,I recently noticed something odd. When I increase my settings, my frame rates go up. This is the world upside down.My system specs.Athlon A64 3200+1GB Corsair 3200 ram120 Gb HarddriveHercules 9800 pro 128 mb video (430/360)Omega driver for the video card.Whenenver I increase my setting in the 3D tab of the video driver I get better frame rates then when I decrease these settings.Also In FS. When I increase the view distance and the cloud details I get better and more stable frame rates.This is very odd.Regards,Peter
