Yeah, I'm well behind the times where my PC is concerned, and an upgrade has been on the cards for some time now. Other, higher priorities, have a habit of getting in the way sadly :wink:I have been browsing many other posts on here regarding a high spec system to run FSX plus other great add-ons such as the NGX, but it may be a while before upgrading my PC gets to the top of the list, so was just hoping I could get it to run on my current system until that time. I would be an avid simmer if my system wasn't so out-dated, and I've really outgrown the 'dumb' FSX default aircraft. I love the detail into which PMDG go in recreating their aircraft, and it's really frustrating that I can't run FSX with higher settings and include more realistic scenery/traffic etc. along with the PMDG aircraft.I have managed to get the 747-400X to run quite well alongside FS2Crew, which has been great in learning some more realistic airline procedures, so I'm really looking forward to the NGX. I have been considering the MD-11 and Jetstream 4100 for a while, but thought I'd save my cash for the NGX.I will certainly let you know if the NGX runs okay...Thanks for you reply.Cheers,Chris.
