My ping is low in Quake2, via internal isdn card, and the frames are smooth in win98, but when i go online in win2k my Quake2 frames stutter, like there is lag for some reason even though i get the same low ping.Quake2 does'nt stutter in single player, so it is related to online play in win2k. Any ideas on how to fix this?

p2 350
voodoo 3 2000AGP(happens with all drivers)
vortex 2

check the swap file and increase if necessary.

stick with win98 as win2000 is hardware hungry unless u've got a powerful computer to take advantage of the OS - that's probably the reason y ur running tht game so slow. also try not to run any programs in the background while playing the game - AV programs can slow down the performance
