Hi! I've just installed Win2000 on my P3-850, 128 MB Ram, TNT2 and now im testing few games. All games are running great but only Halflife makes me worry. When i enter Halflife Win2000 starts swapping and after few seconds it takes more than 90 MB of my ram! It needs a very long time to start playing but then it runs fine... Under Win98 it didn't need so much ram...;( Is that normal or could a reinstall of Halflife solve this problem? Thx, Daster
