i tried now different settings in multisample and downsampling but the used memory is getting higher and higher when planeshift is running.
it looks like the system is not able to remove not needed files from memory. its very confusing to me that no other players have this problem.
maybe its a problem with my windows or an other installed program .. but there are only a few programs installed now and everything is up to date.

i turned sound off, but nothing changed. im sure that there is only one ps client running.

i made a screenshot of my task manager, wich i could post here. but i dont know if its allowed and if its usefull.

ok i changed the fps cap to 30 and it works a bit better now. but the problem still exists. cpu usage is still at 100% and memory usage is growing until the max at about 2 gb and then it crashes. when i quit plane shift the memory usage goes to normal 211 mb. i thought that things are loaded to memory when they are needed and system will clear them from memory when it doesnt need them any more.
i downloaded and installed the game again. i installed an other graphic driver, but nothing helped. i have no idea what else can i do.
or can it be that plane shift doesnt work with a 64 bit processor?

The PS Client uses 100% of my CPU all the time. Second problem is, that it uses 500 MB memory when i start the client and after 10 minutes it uses 1,8 GB. The client crashes when the memory is full after 15 minutes. I still tried to reinstall again and again.

If someone can help me with that problem, it would be very nice.
