I have a Toshiba Satellite with an ATI Radeon 3100 graphics. It only has about 256mb of onboard ram, so i cant play man newer games. I currently have TF2 (Runs, but lags, even in offline mode), COD: WAW, Gta SA(not really a fps, but its good), The counter-strike/Condition zero game pack, and some other non shooting games like AOE and spore. Any good ones i should get? im currently working on getting the original Halo, as well as the Halo 2 for vista. Also i heard Half life 1+2 are good. How graphic intensive is HL2?
You can run HL2 on medium and it still looks fantastic and the older hl series are amazing, simply amazing series and not intensive on even modern mobile chipsets like yours - anyways the list is endless:
Quake & Doom Series
Red Faction 1 (not 2, just do yourself a favor and never play the 2nd one)
So many awesome shooters are out there, but for every good one theres like 5 or more that suck, check out metacritic:
