You should also put certain background or fsx plugin like Ezdok / freetrack / trackir if you have these off all cores except the last one , I use freetrack and I put it on the 3rd core and let FSX spread on the other 2 cores , I am not saying that it will solve your problem as I mentioned earlier that I have zero experience or knowledge about multi monitor setups. But this say me give you a little boost.

@Vgbaron: The "lower" PC absolutely had all of those settings, with the exception of ENB Mod (which as I said I have disabled anyway). In fact, it was flying the 737 PMDG NGX too, which is much more demanding VC wise than the Level-D 767. Ironmaiden: Cheers for the tip! I may try it out.

Hope it works for you .

Right, with AA unchecked I'm up to a slightly more reasonable 15FPS. I suppose that'll do until I get my next GTX285 in SLI. My main problem now is the very frequent (95% of all flights) "out of memory" CTD issue. I really need a way to cure this.

How much ram and how much video memory does your machine have ? and what is the OS ?

Ok. Right click Computer. Click advanced system settings on the left side. Now click the advanced tab. Under performance, click settings. What is the number (MB's) displayed in the bottom box?

The number of MB displayed is 6142MB of "paging memory". The OS is Windows 7 64-Bit.

That's swap memory, what is the RAM size and video RAM size ? Is it 8GB ? you will see your memory when you right click on properties of my computer , it will be on the right hand side "Installed memory"

Okay I don't see how you could be getting OOM's with 64 bit windows, 6GB VAS, 1GB Vram. Hmm.Okay just noticed something. You're using GEX and photoscenery. Disable one of them and try the same scenario.

The PC is showing 6GB of installed RAM (as previously mentioned). I'll try disabling one, but it really isn't a suitable alternative to have one permanently disabled.

GEX is ground textures and so is photoscenery. I think they might be conflicting. Disable GEX (probably easiest to do) and see if that gives you any gain

Unfortunately; I have an even bigger problem now. I'm running two monitors: - One @ 1280x1024 (main monitor)- One @ 3072x768 (TH2G display) Basically, whilst all the monitors usually work fine, after entering full screen mode in FSX, all the monitors connected to the TH2G Unit give an "out of range" error. This problem is very recent, and has only surfaced today. There is an entry in my FSX.cfg file: [DISPLAY.Device.NVIDIA GeForce GTX 285.1]Mode=3072x768x32 Surely this has something to do with it? Also, there's also an entry in the FSX display options called "DISPLAY.Device.NVIDIA GeForce GTX 285.0". What's the difference between .0 and .1???

Delete both the entries, and setup TH2Go from scratch

That sounds like a frequency problem. And that 285.0 could probably be the Nvidia Driver version number.

Unfortunately, I cannot set up the Th2G from scratch, as the Matrox software doesn't work with my PC. It just crashes it every time.
