I'll second the Game Booster recommendation. It works wonders with my six or seven year old mid level notebook. I've not actually had to use it for SH3, which runs more than adequately without it, but if set up correctly, GB can make it seem like ya dun replaced your whole machine with a brand new one. I've heard it even scores a significant performance increase with newer and higher end machines. Best of all, it's freeware. Another tip, I recall there seem to be a few 'hidden' settings for anti-aliasing and such tucked away in an ini somewhere outside, think it's under an SH3 subdirectory in "My Documents" or the like. If ya know what yer doin', ya might just try manually tweaking some settings down, or even disabling them if it lets ya. Just make a .bak copy first, hehe. Depending on the machine, and where it's bottleneckin', things like that can often make a world of difference.
