For some reason(I am pretty sure it is ram related because I have read it on some site before) supreme commander crashes after about an hour. I read on some sight saying that it does something with ram that never stops going up or something on vista(im not a computer expert). My system specs/settings are as follows. Windows Vista 64 bit Ultimate, q6600@2.4ghz stock, 2x2900 xt, creative xfi elite pro, raptor 150 gb, intel badaxe 2, 2xpny 8500 ddr2 ram.
