Okay I got both of these games for x-mas, and ive had nuttin but trouble. First off, I have a Dell Insspiron 5100, 2.4GHZ P4, 512MB SDDRAM, 40gb HD, Mobility RADEON 7500. I installed both games. Doom 3 ran good. Half Life 2 ran, but none of the characters displayed any graphics at all. they were just black blobs. I checked all my system properties and my drivers were 2 years old. I updated my drivers from dell, and the graphics got much better, but still sucked. I then found a Mod for my card that would allow me to run CATALYST 4.12. The graphics for HALF LIFE 2 are awesome, HALO is awesome, but when i run DOOM3 (which ran good before) It runs like a slide show. I have done disk clean, ive dafragmented, i have the latest graphics driver, all my 3D setting are set to performance mode, I just cant figure this out. My driver for my cd rom (Samsung SN-324B) is two years old, but i cant find any drivers for this model. ALright guys and gals.........theres my brain bender. Can anyone help?
