Hi,I Alt-tabbed out of FS last night, and was amazed to see that FS was using 750mb!!!!.Now this seems like a lot to me, is this normal? or do I have a problem somewhere?.CheersDan.

That is pretty much OK with 512MB, observe if the pagefile changes a lot during gameplay, eg. grows much above 1GB.Word Not Allowed

How were you reading the use? If you used the standard XP tools and looking at the page file measurement that does not measure page file in use, only reserved for use. FS only uses 250-280 meg of RAM on my system, including FS Navigator. I do not use aftermarket weather engines, but do have a large number of payware and freeware aircraft, scenery, mesh and other mods installed. If you're using 750 meg of RAM, then I think you have a problem!Allcott

Hi,I used the Task manager, in that there are 2 tabs, processes and performance.In processes the fs9.exe had mem usage 750mb, and in performance the PF usage was about 850mb.It did seem a little high, although I have never looked before so it may have been always been that high.If it is high what could be causing this?, oh BTW I was flying the FSD Navajo.CheersDan.

I think that high RAM usage of FS9 has to do with amount and size of textures. I am not familiar with the said plane but I imagine that if it employs 32bit textures(in addition to complex avionics) then it is your culprit.Kind regards,

Interesting, I always thought that textures were handled by the GFX card?, but I suppose if there is too many textures for the cards memory it puts them in the system memory?.This does not seen to affect performance, I have 1GB of RAM, but here at work, with 3 "hungry" CAD and CAM apps running, I see nowhere near this amount of memory usage.Just wondered if this is the start of a potential problem?.CheersDan.

Dan,Your graphics card does handle textures, but if it exceeds the amount of memory on you card, up to the amount of ram allocated by you AGP aperature setting can be used. Any overflow should then go to virtual memory. Please someone correct me if I am wrong, but this is my understanding.regards,Dave
