Hi all.I have a OOM problem that I would like to have fixed. I seem that when I fire up the sim with NGX I use appx 85% of my video memory (55 - 60 % with the default BE58). When I undock windows on 2nd monitor and look around etc. the memory builds up, and I get around 99%. My RAM memory are around 50% (4GB on WinXP 32bit system).My though was to change the old "GTX280" with a new 2GB "GTX-somthing smart", but I read somewhere that if I did so, I was really if for a rough ride, as FSX is a 32bit software and cannot handle more than a combined 4 gb memory. I think Ryan from PMDG Support was supposed to write an article about this, but I have not been able to find it.Can anyone help me with this issue?Another thing that I do not understand is that my FPS is almost allways the same - not really good, not really bad (around 15 - 25) But it is hard to either improve it or even trying to get lower FPS. If I use REX HD clouds or 512x512 - no difference. Thunderstorm clouds in multiple layers or no clouds - same, same..This makes me believe that my performance problems is not in my videocard, but more a CPU problem, but I can see that almost no CPU resources are used by FSX, and having a i7-2600K CPU (not overclocked) with an old GTX280 videocard I would think the bottleneck would be the videocard. I do not know much about computerhardware, and just asked my fried to put together a computer that kicked &@($* together with my old GTX280 card....but I really did expect more :-)But LOVE the NGX, only problem is that its not for FS9 Best RegardsBjarne Sorensen/Denmark

Upgrade to Win 7 64-bit, Win XP 32-bit can only utilise 3.5gb of RAM (and it's not very good at it). The extra 500mb should solve your OOM's.I run NGX, ASE, RC, REX 4096 textures, FS Recorder, EZDOK, Shade, add on airports on 4GB RAM with 7 x64 without any problems.Next step would be to upgrade the video card.
