I am getting around 28-40 fps on Half-Life 2 even though I have the following system specs: AMD 4800+ Dual core 64 bit cpu Dual Geforce 7800 GTX 512 mb SLI Asus SL8N SLI motherboard 2 GB PC3200 ram (ultra low latency) SoundBlaster X-Fi sound card Nforce 4 chipset. Here is the real kicker. When I set the resolution to 1600 X 1200 with X4 anti-aliasing and X16 anisotopric filtering I get somewhere between 28-40 fps (which frankly is too low for a system like this). BUT WHEN I THEN TURN THE RESOLUTION DOWN TO 640 X 480 WITH ANTI-ALIASING AND ANISTROPIC FILTERING TURNED OFF AND EVERY OTHER GRAPHICS SETTING TO LOW, I STILL GET 28-40 FPS! In other words, drastically reducing the graphics setting has no impact whatsoever on frame rates. I have the latest video card drivers, sound card drivers, motherboard drivers, direct X drivers, etc.. I even reformatted my computer with a fresh install of Windows Xp and installed all the latest drivers on top of this fresh installation, and there was no change! I can't figure out why this is happening. Doom 3 seems to run ok (60 fps with everything turned up to the max).
