ATI x850XT to slow to run any game
sorry if this should be moved into the hardware section but i am trying to run games if i get this working.
ok my comp's specs:
Intel P4 530J S775 3.0GHz (auto OC with mobo up to 3.6ghz)
Sapphire ATI Radeon x850XT
2GB pc3200 dual channel
Fedora Core 5 2.6.17-1.2139_FC5smp
Xorg proprietary display driver
ok so my problem:
I am relatively new to linux but my dad is a genius with it. although since he never uses a computer specifically for games, im on my own on how to figure this out. Right now im running FC5 2.6.17. ok so first i decided to download the Doom3 demo to test out how well it would run. but when i start it i get an error. so then i downloaded America's Army, only to find that it too had a problem and can't execute. also it said some about the virtual memory being too slow. finally i downloaded UT2004 demo, which actually runs, but very very slowly. for an x850xt i should be running that game easily with all settings maxed. so now i have a couple questions i hope someone can solve for me.
1. I know about virtual memory from windows and how you can set the size. is there some way i can increase the size in linux?
2. is there another company or something that makes optimized drivers like Omega does for windows? if not, how can i configure the driver to be 3d accelerated?
3. is there an overclocking tool i can download to set my clocks higher?
any help would be great. thanks.
