raffi: GEX and UTX are not waste. To have a preference for one product over another is fine but to say those two products are a waste is not a fair statement and certainly not an accurate one, be careful when someone tells you that. I use both the Flight1 (GEX/UTX) products and ORBX products and each work well and are good products. If you want to run the ORBX scenery with all the settings turned up then you will probably need something more than a 920 and a 5800. And with ORBX you may be more at risk for OOM errors.

FSX = 32bit application: Max available VAS for a 32 bit app on a 64Gb OS = 232 = 4Gb effectively. As far as your FSX VAS "box" when that 4Gb box fills up with complex scenery/aircraft usage within the LOD that's it, period. If you're not getting OOM errors then you're not pushing FSX that hard.

I am not an expert by any means but based on reading the experience of and consulting with people who are truly experts in both computers and the software code that FSX is written on, and reading the experience of the hobbyists here who have experienced it, I am willing to bet money that no amount of HW power will prevent OOM errors in FSX if the thing is pushed hard enough.

"if it's not ASUS ROG hardware, it's junk" With all due respect. Not true at all. ROG is for the professional overclockers who are out to win contests and need every little voltage/frequency/power management tweaking setting option available to run extremely high overclocks under exotic cooling solutions and run that CPU and RAM within an inch of its life to win that trophy, sometimes even for suicide runs to get that top spot. For the majority of people who overclock just to get more gaming performance or FSX simulator performance ROG is not needed. Especially for us FSX folk. I'm not saying cheap hardware will get you where you need to be but for most of us ROG is marketing and a way to empty our wallets faster. ASUS Professional or Deluxe or Sabertooth series motherboards are perfectly fine. So are upper end MBs from other manufactures. A $75 MB probably won't do it well but a $350-$400 MB will drain your wallet and give you nothing in return but flashy colors and pretty LED lights. And SSDs are nice to have and will provide a benefit but a fast HDD like a newer Velociraptor or WD Caviar Black will do the job well too. As for OOM errors it is indeed an issue. It is well documented across these and other forums, it occurs because of the 32bit nature of the sim and trying to run too much scenery and aircraft with too high settings. Yes it is very important to balance the hardware and there is a critical relationship to balance fast CPU, fast ram and fast GPU or there will be bottlenecks. But it won't prevent OOM errors if the user is pushing the limits of the sim too far.

Hi Rick, The way I understand it, no. VAS is used up because of the scenery (and settings) and aircraft resource demands and no matter if the CPU is fast or memory is fast it will still get used up and I believe a big reasons, aside from not enough VAS, is that FSX will not unload VAS once it's occupied. In other words once you use VAS flying into and through an area, flying out of that area will not free up VAS, the data stays. And it all gets filled up like a bucket (and the bucket is too small) until you approach 4Gb then it kick you out with a OOM error. The higher your scenery and aircraft demands the faster this happens. The ONLY thing that will really fix it would be if FSX could be a 64bit application, and I so wish that could happen.

Hi Wayne, FSX is only multicore aware with respect to texture loading and even that only effectively works up to 6 cores on our desktop CPUs (even though theoretically it can recognize more). Beyond 6 cores the returns are miniscule. Workstation monsters like that one would do nothing for the sim.

Hello, It has been a year or so since I logged into the HiFi forums. Now I have ASN and I need support and I forgot my password. BUT I cannot request an email to my account because the spam filter won't accept my answer: "What does the F stand for in FS"? If it is not "Flight" than what is it? Because of this I cannot get any support on that site. Please help. Thanks
