So yeah, me and my friend Justcause have both been playing PJ64k on vista at a computer lab (lack of windows computer at home leads to LOLFAIL) for a few months now, and we keep getting the same problem: everything will work just peachy for a while, and then, after about a week or so of playing on any given computer, said computer, which has been running like a dream thus far, will begin to get crazy lag spikes, and it won't lag in the normal way. The game runs at a good speed-60 fps- and every 15 seconds or so it'll freeze, the fps thingy will read 18.01 or something similar, and then after a little bit it goes back to normal for 15 seconds or so. then FREEZE! at any given time, 2/3 of the computers in the lab will be infected with teh lagzorz. I can manage all right by switching until I find a good 'puter and then sticking with it till it borks, but it's annoying and sometimes all the good ones are taken. Has this happened to anyone else? any advice?
