Today I bit the bullet and went out and bought Windows 7 64-bit to replace XP 32-bit.. I formatted my PC and did a fresh install. The only software I have loaded so far is anti virus and FSX and the PMDG 737-NGX and MD-11. After 3 flights without a CTD, OOM, Panel Freeze or the need to reboot between flights, I am feeling good about my upgrade. FSX is running a lot smoother, loading scenery a lot faster and not suffering any of the slow graphics loading I used to get with the 737 and Md-11. Before the upgrade I was getting so many Panel Freezes that I was pulling my hair out. Fingers crossed, those days are over! By the way, is the autoland system a fair dinkum bit of kit on the Qantas 738? Brett Williamson

Brett, Might also mention your PC specs, monitor/card etc ... just for reference.

System is pretty dated now. Intel Q6600 Quad Core 2.4ghz.4 GB RAMRadeon HD 5850 1 GB graphics card.ASUS motherboard. Can't remember which one.

My PC specs are similar and I get good frame rates with the NGX even at add-on scenery areas with all sliders on 50-75%!! Great job PMDG!!

Hey Monitron - That's great that you've improved FPS etc. Have you considered OCing your CPU? I used to have a Q6600 and got it up to 3.2ghz with no problem at all! That'd be a huge improvement. It's really easy too. I got my Core i5 760 from 2.8ghz to 3.5 with no problems at all! Saw a very big FPS increase.
