You do realize that is 99.9% marketing? They are more interested in gathering data from your computer than optimizing anything for it.
I've had nothing but great experiences with this software, it's made my gaming within known games much better and faster. It even allows me to capture the errors and programming failures with it's video capture system, that the in-game film viewer didn't catch... (shadow seizure feature, framerate akin to an Apple2e, floppy chicken opponents, CV groups uncontrollable, master of the universe tree branches)
So if you're going to allude that another bit of software "chews up performance" with respect to your software, I would respond with, wow, is AH3 THAT fragile?
I KNOW my hardware can run AH3 5 times over, yet still doesn't seem to run "well". If I had AH3 in my geoforce experience, I wouldn't need to tweek my system to get the game to run as it should... (it really bothers me that I have a more powerful system than the one this game was designed on, yet cannot get the game to appear as it was intended)
Sigh...i guess thanks geoforce for my poor experience with AH3?
