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?Well, what kind of video card do you have? Does it meet the requirements of BOTH video cards?

[glb]Flame[/glb]I have a mobility Radeon 7500. its a directx7 card, but i have directx9 installed. and yes, it meats the criteria for both games. and it worked well with Doom3 before ii installed the newer catalyst drivers.Well, that might be your problem right there.... If you have a direct X 7 card, then I'm not so sure that upgrading to Direct X 9 was such a good idea...

[glb]Flame[/glb]DOOM3 is pretty resource intesive. Lower all of its graphics settings and close down other uneeded programs.

I've used DirectX 9 on a DirectX 7 card before I think...
