i played the demo of Geneforge 5 and Avernum 6 and even at max graphics they both ran VERY smoothly, i registered them and they still worked fine, at first. i reopened G5 one day and the lag was intense, i could barely move the mouse, so i turned down all graphics, lowered my comps resolution, even closed my minimap and the game was tolerable at that point. it's been like this ever since except it occasionally goes back to being fast, but it always reverts to extreme slowness. A6 was the same, fast at first, then constantly slow. ive tried reinstalling the game and everything. i use windows vista with a HP pavilion dv6 laptop if it helps.
