Guys, I'm having a serious performance issues with the JS41 in all scenery and whether situations. Comparing to MD-11 for example, the MD-11 is so less performance killer than the JS41. And the MD-11 seems to be a mutch more complex aircraft.With the JS41 I usually get 8-15 FPS, with constants glitches and stutters.I know, it's a whole new approach to simulation, and also isn't that easy to simulate a turboprop aircraft, and so on. But my machine is not that bad, and I barely can fly with this baby.Finally I have to say, fly this baby it's a new experience to the Flight Simulator X, the sensation of "being there" it is so amazing. Thanks for that. My specs: Core I7 920 Clocked to 3.3GHZ6GB RAMZotac GTX285 1GB Ram.Windows 7Paulo Bernardo S. SilvaBrazil

With a 3.3Ghz clock speed and 6GB of RAM plus a GTX285 you should be getting better frame rates than that. These are very similar specs to my system except I have my CPU set to 2.66, and I've never seen frames in the single digits. I rarely see below 18 or 19, and when I do it is only in extremely dense areas with a ton of traffic (I use MyTrafficX). When I overclock, I rarely see frames below 25. Make sure all your drivers are up to date, including drivers for your mother board etc...What are your fsx display option settings? Things like aircraft self shadowing, bloom, and maximum water settings, high autogen and traffic settings (especially with traffic addons) can hit performance hard. Also, I would suggest setting your frame rate limit to unlimited, unless you are experiencing blurry texture loads in scenery.Let us know.

I had a very serious hit in FPS on the J41 and I discovered it was due to having aircraft self-shadow enabled in DX9 mode which I have used to date for some screenshots in some of my articles. I removed it and immediately gained 5 FPS. I'm hovering now between 18 and 24 FPS (frame locked). I could tone down other frame hitters such as the cloud density in bad weather but flying the JS41 makes it very hard to do because it's just so entertaining to me (not so much my virtual pax) to do the turbulence and icing thing in no visibility :)I have a water cooled QX9650 running at 4GHz and the JS41 gives the box quite a workout.Cheers,

Paulo, I adjusted a couple settings in the configuration manager that made a big difference. The first one was keeping the high resolution displays, but reducing the EFIS refresh rate settings down to 6%, all four of them. It doesn't hurt the look of the displays at all in my opinion. The other change was under "external model options" selecting the medium version. Unless you like to gaze at the outside of the plane on a regular basis, you won't miss it.Curt

Wouldn't that mean that those screens are only refreshed once a second? Is that still properly flyable? I've set mine to 50% to get 9 refreshes per second. On the other hand I'm having a very hard time spotting a difference between normal and high res instrumentation. Maybe my screen is just not big or high res enough.Regards, Oliver

I have an E6600 with 2GB of RAM so I had no other option than to turn down settings both in FSX and in the JS41. I use no scenery addons.One other point to take care of is system maintenance:- up to date drivers and OS patches- stop all irelevant background software and unneeded services- defrag (Win 7 and Vista do this automatically)Here are my J41 settings:- Normal Resolution Displays- External Model: Low- VC Model: Low- Capt Displays Refresh: 100%- FO Diplays Refresh: 0%With these settings I get between 20-25FPSCristi

So far I've set it to ...- Normal Displays- High Models- 11% Captain, 50% FOI fly from FO-View (so I don't have to look at that non-functional WRX all the time :( ). With some descent FSX settings, I get 15-25fps on my subnoteook (2.53GHz P9500, 4GB RAM, 9600GT). Not too bad. And there's still room for tweaking.Regards, Oliver

Good tips here guys. Thanks all.
