Alright I've tried everything i can think of to try and fix this. I have an AMD XP+2500 processor with 512 DDR pc2700 ram and a Radeon 9800 pro and in natural Selection the mod for Half Life 1 my frames randomly go from 70 to 20 or below?!?! I cleaned out the fan since there was dust in it. Ive updated the drivers and all. Now when i had my radeon 9000 pro i was hitting 80 frames and staying there no spikes or anything. Can ANYONE please give me some suggestions on how to fix this!?!?!??!
