so i just discovered this game (thanks to these boards), and it's loads of fun! still not very good yet, but enjoying it none-the-less. im playing on a Rev D 12" PB (1.5 ghz, 1.256 MB RAM) and during intense battles, the framerate will really slow down. anyone have any performance enhancing tricks? i heard something about changing com_hunkmegs to 512 or something, but the setting never seems to "stick". any and all help would be appreciated! and does anyone know why sometimes i get a message about unpure .pk3 files when i just installed the game?? thanks!!!
