I was wrong, and I admit it. Software problems still stand, but the performance is nothing short of amazing. IF I'm not doing anything wrong. And yes, same Nvidia Inspector profile is being used, both applications are under the FSX profile. I took some time to review the performance, now installed vanilla FSX with SP2 (don't worry, my original FSX is backed up, safe and tucked in the backup folder). P3D with the same settings. Here are some results and screenshots of the same situations in FSX and P3D. Settings comparison: Screenshots comparisons: Please note, in these screenshots there are FPS numbers, though not completely realistic due to simulator being paused. And some numbers: FSXMark11:FSX:Min 21Max 35Avg 28,117P3D:Min 32Max 41Avg 37,033 Cloud AA Test:FSX:Min 26Max 37Avg 28,767P3D:Min 46Max 58Avg 50,600 Note also that those tests are based on 30sec run (Clouds AA Test) and 60sec run (FSXMark11). Also 2nd run has been taken as the measurement (once ran, flight reloaded and ran again...). Btw. the forum is resizing images to be smaller, I wanted to post 1920 width to better show the water difference, but it can't be done. Sorry.

Thanks for clearing that up.

Yes. I can also tell that for me, the performance increase is significant. Did a test-flight around the area of KSEA and where this usually is the lagfest of the century in FSX; it was actually quite smooth in P3D. Very impressive. However. For some reason, the NGX isn't performing nearly as well for me under P3D. FSX seem to have about a 10FPS gain over P3D. Extremely annoying. Any one else experiencing this? Regards.

Could you take a screenie of the Nvidia Inspector settings?

Glad you got it sorted. A very informative post. Thank you Word Not Allowed

Note: I added prepar3d.exe to the application list.

Excellent comparision!

Yes, fantastic comparo! Look fwd to seeing others. Massive differences here.

And now, as tests furthered away, I was loading sceneries and all, and noticed a hard fall in FPS when installed some sceneries at my default LOWS airport.Around 20% less in P3D.So I started messing with sliders, 1024 texture, lower AG, no water reflection...I couldn't bring P3D to be higher than FSX.No scenery addons, and I have been getting in short 10sec flight, FSX 140fps, P3D 105fps. My final verdict is: still needs a lot of work, a good start though. Gonna keep FSX for now...

Word Not Allowed, If you are registered at the Orbx forums, this should be an interesting read. For those who aren't registered : adding third party content that has not yet been adapted to run on P3D MAY seriously impact your framerates.

Wow, this is all getting very tempting. And now I saw Aerosoft has released Corfu with a P3D version also. This is going to be very interesting! Can't wait to see how this progresses, and I might even try it out for myself if it all keeps going uphill this way.

Aerosoft has released CorfuX for P3D, but it is just for testing at the moment. http://forum.aerosoft.com/index.php/topic/48878-corfu-x-110-now-also-available-for-prepar3d/page__hl__corfu__fromsearch__1

Word Not Allowed, one small difference that could also impact performance is your global texture resolution. Very High in FSX equates to 1024x1024Max in Prepar3D is 4096x4096 which is 16x the texture size
