Zeeliv, are the demos you posted on the thread the atdemos that glc1 is referring to with "Anyone know how to get either to run one of the atdemos?" I have no problem with timedemoing, so if I can get these atdemos I can easily see if they work or not. Anyway, I timedemo'd with your zdemos (using my cfg geared for maximum fps and visibility)... results: z1-112.1; z2-85.4; z3-160.0; z4-118.1
