Hiyah, I just installed Windows XP professional on my home computer and I had a question regarding ATI RADEON 64MB agp video cards or any other cards; I upgrade from windows ME and had the refresh rate on my monitor set at optimal. Which it gave me that choice in Windows ME with the ATI driver. I also uploaded the XP driver for ATI on my machine to so, it does have the same program as ME but no optimal! My refresh rate was at 80khz 100hz now it's 65mhz 85hz. It won't go higher than that! I haven't tried playing a game like "half life" but I did use Oozic player (heavy 3-D graphics) and it was stuck at 85hz. does anyone know how I can get back my faster refresh rate?
