Hi,
I recently bought this very nice game. Sadly, the version was german only, but by uninstalling it and then reinstalling it online (faster than from DVD!) I got the english version *smile* - I am writing this as I did not see this slowdown problem before switching to the english version, but I did not play Advent with the german one.
I really do not know what causes this slowdown. The user interface doesn't even handle mouseclicks properly. Playing Advent is a good way to even further increase this problem. The slowdown does increase constantly towards the end of the game. After winning and continuing, the slowdown is even present when there's no hostile force left!
When the slowdown occurs, the game won't even speed up after ending it!
Computer specs:
Vista 64
AMD Phenom 9500 (anti TLB software used)
8 GiB DDR 800 RAM
nVidia GTX 295
Looking at the task manager it seems to me that the game is also not using the multiple CPU cores.
I've seen a few mentions of this problem, usually those people reporting it being flamed because noone could believe it. Thus it seems that it does happen, but only to few people. This problem is real and destroying the fun immensely. Has anyone found a solution?
