Hello every one! I am running Prepar3d v3.1 on pretty much every thing maxed out expect AI traffic. On a typical session I use a number of addons like airport scenery ( I fly to flytampa dubai a lot), REX 4 + soft clouds, Active Sky Next, Ezdok, Trackir, PMDG 777, GSX Ground services. I thought I could run this with reasonable frame rates because I think I have decent computer. Specs. i7 6700k Overclocked to 4.4ghz 16gb ddr4 2666mhz Ram ROG Maximus viii hero Motherboard. 250gb SSD + 1tb HDD Two GTX 980 Ti running in SLI config. Now, I also have a 4k monitor so therefore I have been running all this in 4k resolution so far. On a fully loaded airport with mostly every thing maxed I get between 20 to 30 fps with few drops to about 15 fps. I do love the eye candy but it does start to stutter at times which makes me want to switch to lower resolution. And here lies my question. I get absolutely zero difference in performance when switching to a lower resolution. Frame rates stay exactly the same. I haven't done any tweaks with the cfg file. When I lower the resolution to 1440p in games like GTA V and BF4, my frame rates increase by 20 to 30 fps. But why not in P3D? PS, These are the screen shots I took in game with frame rates. They were VERY unstable. Here is another one just a few miles down. Notice the frame rate drop On this particular approach the frame rates ranged from 20 to 60+.
