Okay how about an Athlon 650mhz, 128MB of RAM, and the funkiest GeForce256(32MB no DDR or AGP 4X sometimes seen as PCI with 31.5MB) ever, Win98 SE and around 3 GB left on my Hard Drive for swap files
and a Road Runner cable connection.
In contrast Postal 2 ran fine, Q3 Tech is all good
oh what tweaks can help if not myself then someone else to improve performance

oh and for the grammer freaks sorry for subjecting you to my writing
