Fellow flightsim/aviation enthusiasts,I have a problem with the Queen. Basically my problem is with performance/frames. When I start in the Queen (VC) everything is fantastic and frames are where I expect them to be. It's only when I execute my flight plan (not necasarily long) that my frames drop thus performance. When using FMS for my flights there is a significant drop in performance. However, when I land and the FMS ends the route frames jump straight back up and the performance is great again. I can fly circuits of touch and go around an airport and the Queen is the greatest aircraft to fly, performance is superb, its just when I load a flight plan performance drops. My system is a AMD 2800 XP, 6600 GT 128, I gig RAM, ASUS A7N8X-X. So my questions are:-Is this a normal characteristic of the Queen? SHould data in the FMS affect frames/performance? -My machine handles the Queen superbly without flight plan loaded in FMS, is it simply that I need to upgrade to be able to enjoy flights? Thanks for your supportTristan

Tristan,Have you upgraded to latest version 1.1? There was, I think, a problem with the flight plans in the first release version.Hope it helps,

Hi,Yeah I've updated the Queen with the service pack but it doesn't seem to help. THe thing is that you really notice the difference once you hit the execute button and when FMC end of route message comes on. Tristan

STEP through your ROUTE looking for a Waypoint that shouldn't be there or a great distance between two waypoints. I use to experience this with the 737NG.Floyd

Hi Floyd,Do you mean that the closer the distance between waypoints the less stress on system resources? I would have thought that the more waypoints there are the more taxing it is on the system. Before I would delete waypoints that are too close togeather in order to create less route pages in an attempt to improve performance. Tristan

Tristan,Try reducing your 'Traffic' percentage or, even completely off.AI is a big FPS eater.Dave T. .........On the Devon Riviera and active 'FlightSim User's Group' member at http://www.flightsimgrpuk.free-online.co.uk/

Hi,I don't know if traffic is the problem, because I can fly the Queen without route and traffic affect on performance in minimal, well my traffic package anyway. It is so obvious that the FMS hits the frames, especially after I hit the execute button. Tristan

I'm not a expert on how PMDG aircraft affect system resources buta couple a years ago my system went into a super slow frame rate crawl after I pushed the FMC EXECUTE button. I went through the LEGs page and found that one of the waypoints had a distance to it of over 4000nm even though I was flying a 200 nm trip. It was obviously two waypoints with the same identifier, one half way around the world the other 50 nm away. I never could get the waypoint 50 nm away to load. Every time I'd try to my frame rates would go from 28 fps to 3 fps. I eventually just left it out and my frame rates stayed normal. Try a different flight plan with different waypoints and see if it makes a difference otherwise good luck.Floyd

Tristan-Depending upon your system, what you are seeing is not entirely unusual. Consider for a moment the amount of mathematical computation that must begin taking place the moment you have a route of flight entered: Fuel planning/consumptionHeadingsTracksClimb/DescentsThrust for climbs/descentAdjusting climb/descent angles to maximize aircraft performance.Adjustingclimb/descent angles to make the route flyable...These are justa FEW things that are continually being considered by the FMC once the route is loaded....When there is no route loaded- the FMC "stops caring." Thus it lightens up on the math processing taking place on your machine....One of the respondants above mentioned that having waypoints very far apart wasn'ta good idea. He is correct. By deleting intermediate waypoints you are actually making the math process for the FMC worse- because it needs to constantly adjust along great circle calculations that are significantly easier when the distances are "normalized" rather than when they are great....hope that helps...

Rob,Yeah I guess that makes sense. I will try a different flight plan and take into account your suggestions. CheersTristan

Regarding your 6600 GT.I have had only one ctd since prior & post patch,flight from egll to fact.I installed the lates driver for my 6600GT & done the same flight with no problem & have done at least three other long flights since with no problems,,"81.95_forceware_winxp2k_international_whql.exe".Hope it helps.cheers Phill

I should add to my above post by saying,that when i had my CTD from EGLL to FACT that i was 2 hours from fact at the time.I decided to take some screen shots,so i paused the sim "alt tab to the desk top".Saved some screens using paint, went back to the sim & CTD.With active sky running,fs passengers running it was apparently to much of a strain on my system not to mention the strain on me.Phill
