Amazing, but I get decent FPS in Mass Effect and Witcher on medium details. 8D

And are you running MSDOS on the P133 rig or an early Windows like 95 or 98?

Mixed actually. DOS for older games and I used to use that for demos from parties, but I dont use that very often anymore. Then I have Windows 98 SE on that. That system is a pain actually... Some games doesn't like my 32MB memory, some doesn't like that I have SB live sound card, and some just dont like me I think. I had AWE32 on that machine, but it got 1 decree burns after my amplifier backfired thru headphone jack... :D
The DOS side is very much tweaked actually. I have QEMM + DESQView system, 4DOS and standard DOS. With and without Extended memory and some game specified boots...
Desqview + Master of Orion = Ultimate Cheat. ;)
Now I sound too geeky, so I am off. :D
