Also, dont set a cache that's bigger than about an 1/8th of your overall ram, it'll likely lower FPS rather than increase it. This will allocate ram to be used as a cache for the game. If you have 8 GB use '-heapsize 1048576'. Seems that this game really struggles with RAM allocation. Under the general tab select “set launch options” and here you have type in a command depending on how much RAM you have. 'For this method to work, all you have to do is right-click on the game’s exe file and open properties. Gloomfrost: Just got the game today and haven't played it yet(still installing)from what i have heard in several places is if you have lots of ram over 16 gigs that that heapsize command can make a big difference for performance.
