In my quest for better FPS

[GunnerMan]

...In FSX I have been doing exstensive tweaking, fixing system files, and overclocking to get the best out of FSX my system will do. I want to just buy a new computer but it is a bad time to do so so anyways.

During my tweaking extravaganza I run DXDIAG and it says my Graphics card has an approx. total memory of 1246 MBs. I run an 8800GT wich as you know only has 512 MB of Vram on board so my conclusion is Vista(64) is reserving an amount of ram (about 500 MBs) for the video card. This explains why im using almost 1 GB of system ram idling on desktop.

My question is, how can I turn this sharing off or adjust it to a more reasonable level? When I run TaskMan while I fly FSX I see my CPU is getting worked at 100%(of course) and mym memory is using 1.67 GBs then it has 573 MBs cached(probably for video) and 4 free. So if it is true that the cached ram is reserved for the gpu then it is wasting it because as you can see it is hardly touching that extra ram.


Thanks a bunch

Ok I did some reading last night and found that this cached ram is reserved for the SuperFetch feature. Supposedly what this does is reserves some ram that windows can put files in that it thinks it's going to need/ use next. So instead of accessing the HDD every time something new is loaded it can get the common files much faster from the ram.

From what i see it isint using much of the superfetch ram so I would like to reuce it because FSX dosent have a clue what it is.
