Long time reader, first time poster lol. I must say these tweaks really do work. I never thought my system would be able to handle doom. Here are my specs.
1.33 Ghz AMD T-Bird
512 megs PC2100ddr
Biostar M7MIA rev 2.00
geforce 3 replaced with fx5900xt oc
I can now say this system runs doom 3 on high quality at 1024x768 with slowdown only occuring with lots of monsters. I swear, the wonders of the t-bird hehe
