Hello I built a new machine with 9950X3D+RTX5090 mainly for Pimax Super and MSFS 2024. I saw VR Flight Sim Guy got 40 fps in New York ( https://www.youtube-nocookie.com/embed/wjAdf-JbNYE ) . He has a 9800X3D, and that is the only difference between our system. I setup my MSFS 2024 and Crystal Super exactly as his according to his setup video ( https://www.youtube-nocookie.com/embed/XPseAZDaxKQ ), but to my dismay I only got 30 fps at most at the same location (London City Airport and New York). I tried Process Lasso and forced MSFS2024 to run on the 3D V-cache cores. I also tried enabling turbo gaming mode in the BIOS, which basically turned off the non 3D V-cache cores and made 9950X3D into a 9800X3D with 200mhz more clocks. All in vain. I am still 10 fps less than VR Flight Sim Guy.
Some other information. We both set the rendering quality of Crystal Super to high, which is 6240x6280 for one eye! That’s crazy resolution, and it makes 5090 the bottleneck. My GPU load is 98%, while CPU load is only 20% - 35% most of the time. We both set the anti-alias to TAA in MSFS 2024. That is also big load on GPU.
Can you shed some lights on what I have done wrong, and what else I can do to increase the fps? 10 fps in VR is not neligible, and I really need that, other than I have a theoretically better CPU than VR Flight Sim Guy yet I still got 10 fps less!
The only thing I can suggest is to put ONLY the sim on the Vcores. (There are some essential Windows processes (like Registry) that must not be changed. Most of those you can’t change.)
But other Windows and other app processes should be all assigned to the non-Vcores. That gives you a capability the single-CCD 9800X3D does not have.
This video helped me understand how to optimize my 7950X3D, and it should apply just as well to your 9950X3D.
Other things: I’ve found the best performance with my 7950X3D when I disable Windows Gaming Mode (to endure that Lasso is the only process scheduler,) enable Bitsum Power Plan, and set core parking to OFF using the Bitsum tool.
I also changed a lot of the Windows processes to Idle priority. They run fine.
The video explains that as well.
Thank you very much for the help. I will watch the video and report the results.
Using the methods in the video, I still got the same result, even a bit lower.

Can anyone with Crystal Super and 9800X3D and RTX5090 try VR Sim Flight Guy’s configuration in the link above? I bought 9950X3D only for playing MSFS2024, and I’d definitely change it to 9800X3D if I can get 10 more fps.
There is absolutely no reason to get a 9950X3D just for MSFS (or any game). If you want the best performance and only play games → 9800X3D. If you do heavy workloads AND play games → 9950X3D.
Process Lasso isn’t needed anymore (and wasn’t needed for a long time). Just make sure to run Windows in balanced mode and not high performance when you are using a cpu with 2 ccds (7950X3D/9950X3D)
I am light on workload. I just want to get the highest fps in MSFS2024. Would 9800X3d be better in that case?
Since you already have the 9950X3D i would just keep it. You’d lose too much money in selling it because nobody will give you msrp for it.
In some MSFS 2024 benchmarks the 9950X3D is a little better, in others the 9800X3D so they are more or less equal.
It always depends on the scenario they are testing in and it could even change with a sim update. In Toms Hardware test of the 9950X3D it was better in 2024 than the 9800X3D, in a relativley recent PCGH test the 9800X3D was better.
Regarding your cpu usage you mentioned in your earlier post: It averages the load from every core. So you can and will be limited by main thread as your main thread (core 0) will be at 100% while every other core bobs around at 20%.
I just zapped through that guys video and i think you misunderstood him. According to Pimax the display resolution is 3840x3840 (50PPD) and in the video he claims he played the game at the mentioned 50PPD.
When he mentions 6240 x 6280 (no idea why it would be 6240 and not 6280, probably a typo on his part) that’s both eyes combined. You said you set it to that resolution PER eye. So change your resolution to the Pimax’ native resolution and you should get the same or similar results.
Current GPUs are just not powerful enough for resolutions that high with acceptable framerates. And yes, even the 5090.
Have you tried foveated rendering? That should help with performance. Also i don’t see any of his in game settings he is running. The only thing mentioned is the resolution (and that he is using TAA)
Thank you for the reply. Yes I am wrong in saying that the single panel resolution is 6240x9280, yet my configuration is exactly the same as VR Flight Sim Guy, as I exactly copied his from this video: https://www.youtube-nocookie.com/embed/XPseAZDaxKQ . Now it’s more a psychological grudge as I can run it more smoothly after opting into su3 beta.
