You're going to have to tell us which game you're trying to play before anyone can help you with that. The Spring engine runs several games: http://springrts.com/phpbb/viewforum.php?f=47
This is actually a community of people who make games
I think he is having the same problem I am having. Game plays fine for a while, then after about 15-20 minutes, the map goes white and the terrain disappears, game bogs down then it locks up.
Game seems to be a memory hog, last time I saw a message about running out of RAM. Seems to happen after a lot of orders have been issue. I think it is related to the unit path cache, as that seems to take a long time to load before the game starts.
I'll have to post my own thread about this, but I think the problem is with the game engine, as it happens with several mods, and previous mod version too. Updated to latest nVidia graphic drivers, did not make any difference.
Game engine used to run like silk on older versions on this same PC, something in the last few versions is doing this.
But, Maj_error, what you are reporting is a known bug with a known cause (nothing to do with path cache) - post your infolog.txt and springsettings.cfg please. Also test if it leaks for you with the latest engine testing release (see engine forum for download link) because it should be fixed there.
