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.com/watch?v=wjAdf-JbNYE&t=2s ) . 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.com/watch?v=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!

Edit: Thank you guys for the help.I now just wonder if any of you have 9800X3D+5090 or 9950X3D + 5090, can you test this graphic configuration below, and get the results for comparison here? Thanks a lot!

You may want to share your exact settings on his discord and see what kind of response you get. He may have made an error with the settings used in his video or there is another component that wasn't disclosed. I'm assuming you were running DFR?

My friend, with the same system, except 128 MB of RAM, has HT off, and his performance is better. Why? I can't answer, but you can try and see if you might get lucky.

I have 9950X3D + 5090, and I can't even run my Crystal Light at sth like 6000x6000 (oversampled) at TAA. I would say it's great if you even get 30 fps at 6240x6280 TAA. I don't believe at all 40fps is possible at this resolution which is over 70M pixels total.

I will post on his discord to find out. Thanks for showing the way.

I have some doubts too, but his videos clearly shows 40 fps above new york and london. I just can't help being envious. 🙂

I think the keyword is "TAA" - that's taxing the 5090 as hell pushing close to 80M pixels per frame. Hard to believe he can get 40fps in VR with high / ultra settings while flying TAA at such an extremely high resolution.

At NYC I only get around 45fps with high/ultra settings (TLOD=250-300) with DLSS Quality + 4200x3500 (cropped) in Crystal Light.

VR Sim Flight Guy set most of his other graphic settings to medium or low, and his captured videos are very smooth, so I think that is possible. Can anyone try his configurations in the link above to give it a verification? I am really curious to know.

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.
