3 GHz I7, 5054 graphics, 8 Gb of memory (Imac under Bootcamp), no tweaks except the ones suggested in the Introduction manual, no hotfix, and I haven't had a crash in days. Henri

Adam. I see your specs are very close to mine except for a couple of clicks on the oc and a SSD. How's your performance with 65% UT2.

Well, first of all, I just looked in UT2 and I thought I had set it to 65% but it's actually at 100% (!). Now I'm not so disappointed that I occasionally drop to 14 FPS. Like last night I was at KMIA gate D9 with most of the airport's gates full, and me looking over the glareshield right at all of it, and it momentarily hit 13-14 FPS. And this is the story anywhere with lots of traffic, ATL, DFW, etc. As soon as I had pushed back and the traffic wasn't in my field of view, I went up to about 22-25FPS. Traffic came back into view lined up at 26R so frames dropped to 15-20FPS. But at no time was it stuttery or "flickery." After I was airborne, I was hitting my external lock of 30FPS in fairly heavy clouds. I honestly thought I was running at only 65% and was rather disappointed by the performance of my machine. Now that I know I had mistakenly set it to 100% somehow, I'm a little more satisfied! I can tell you the only differences between our systems shouldn't make any performance difference EXCEPT I was cheap and bought the regular GTX560 instead of springing the extra $30 US for the Ti. The SSD doesn't show much in-game performance gain. I do know that because of the SSD, FSX loads to the GUI in like 5 seconds and it only takes about another 3-5 seconds to load the sim after hitting "Fly Now." Adam

My copy is running splendid on I7 960 @ 4.2 ghz. only problem I have is if I load a saved flight with the NGX the Sim crashes. But if I select the cessna first then NGX its no problem.

Core i7-920 @ 3.35 Ghz (low because of stock cooling), Gigabyte EX58-UD4P Mobo, 6GB DDR3, Radeon 4850 512MB, Windows 7 Professional 64-bit... Havn't had a CTD yet (except ending a flight, kinda lame but acceptable).

The freezes/CTDs are a memory issue, it's nothing to do with CPU type - we'll be posting more information shortly, just want to make sure we have the explanation completely right first.

Thanks Ryan. The explaination of the cause is as important as the fix itself to me.

read Specs below...no problems after hotfix

Q6600 Quad Core 2.4 ghz stock, overclocked to 3.0 ghz Was running fine from release day except for the 2 second freeze but it never crashes just resmes after 2 seconds. With Hotfix 1 it was still there, but have yet to see it occur with HotFix 2. Another thing to take into consideration is the Video Card Drivers. Since I am using an 8800GTX and nHancer I am still using an older driver 8.17.11.9745 from way back in 2010. The reason being is the last version of nhancer was 2.5.9 and supported up to the Nvida 179 series drivers. My current old Driver and nHancer work without any problems whatsoever. So until I upgrade my video card to a 500 series when I will need the 200+ series Drivers I have not upgraded.

Zero freezes and no problems for me, except piloting errors that i make not knowing how to fly the thing. I only have between 8 and 15 fps and it is perfectly smooth.

Everybody including me, is running around scratching thier heads looking for a common denominator. I hope at the end of all this, PMDG doesn't just say here's the fix, now go fly. Because i for one would like to know what is causing this.

Hi Rick, Is your HDD 2 running as drive D: ? I remember having problems when FSX was first released and I had decided to not install FSX on the C drive, but on a completely different HDD to the OS. Maybe the key to the problems is not so much the hardware, but rather the way people have installed FSX and whether it resides on the same drive as the OS. FSX is running great here on my iMac Jerome

It is actually drive E and my O/S is on drive C, but as PMDG recomends, it is just E:\Flight Simulator X. Apparantly with W7X64 systems, installing in C:\Progam Filesx86 can cause problems.

i7- 980 extreme OC @ 4.5Ghz water cool, asus rampage MB, 2 gtx 480 cards water cool, obsedian case, windows 7 x64fsx, rex with weather enabled no problem climbing . I limit my frames to 35 and it stays very smooth no glith at all.

Installed NGX tonight. Have no problems to speak of. Frame rates are fantastic, and no CTD's. I'm on a Core 2Duo Processor on Windows 7 64bit. Hopefully there is a solution for those who are experiencing CTD's.

I have an i5 2500K, no issues whatsoever. Not before the fix and not after (knock on wood) Well, I had one tiny little thing; the radio alt@ 9000
