i dual boot linux and windows. I can play games like quake in windows and they work fine, but not in linux. I've tried several distributions, right now i'm using mandrake 8.0. Linux uses the 224 megs of ram that I have, and it recognizes that I have a k6-3 400mhz processor and a voodoo banchee 16meg video card. It doesn't matter what windows manager or desktop environment I'm in, I've tried KDE, Gnome, some other ones from the internet that are supposed to be faster, and even in just regular Failsafe mode. Still, I cannot play quake3 because it is so friggin' choppy. I've tried other games, and those are choppy too. Also my opengl screensavers are all choppy. I am absolutely positive that linux uses all my hardware to full capacity, the only thing i'm not sure about is the opengl drivers for the video card but i don't know where to get those. Please help me!!!

Check how many daemons and process are runing in your machine and do a down or disable the process you dont need. You can use gtop in Gnome. It's in Utilities - Performance Monitor (I gues, cause I use Spanish version). you also can renice some process or increase the priority for quake. Remember that Windows are not fully multitasks as Linux, and one process control all the procesor, not like Linux, where the kernel switch the procesor into the diferents tasks.
