lo, i have a problem with unreal tournament playing online: my maximum framerate is 100, but i can get 100 only if playin at netspeed 20000. though i use a isdn (fritz card pci) connection, netspeed 20000 is way to high under linux, coz with only little traffic my frames drop like hell. is there any chance i could change this situation? coz with netspeed 5000-10000 my maximum frames are 30-50, and that's imo too low. specs: suse 7.3 amd tb 1,3 ghz 512 mb sdram geforce4 ti 4200
