For some reason my OS(windows 7 professional) isn't releasing cached ram when it's needed. I have 4gb in my system, and I thought that should be plenty for now, but crysis in some parts is using about 2.4gb, and the os has around 1.3 in cache + whatever's left on background processes. Once the full 4gb gets used up, about 2-4minutes into gameplay from where I have my save, the system locks, and game crashes.
The part where it does it is on the aircraft carrier when your fighting the alien walker.
Can I manually set this cache to a smaller amount? I thought it was supposed to automatically release ram from cache when it is needed.

Thanks.
