Hi folks, I’ve seen some videos on youtube that show quite a considerable bump in fps when upgrading a cpu from the 3700x to the 5600x when sim racing in iRacing and Asseto Corsa. I wonder if there’s anyone out there who’s tried this in MSFS?

Thanks for sharing those images. Definitely an improvement alright but was this also in VR or just 2D performance?
Significant, went from 3900X to 5800X and there’s quite a lot more headroom for CPU intensive options.
Max attainable FPS for me in VR went from 35-40 to 45-50 before CPU bottlenecking with reasonable settings
Thanks for the information guys! If i can wring an extra few fps out of my rtx3070 system with a cpu upgrade it’ll make all the difference.
It will, but only assuming you were CPU bottlenecked before. Have you checked to see what is limiting you?
Otherwise it won’t necessarily give you more FPS since your GPU will still be the limiting factor, but it may give you smoother more consistent frames and avoid CPU related slowdowns in certain areas (ie if the CPU ever becomes limiting for short periods or in certain places it will help there).
Also as mentioned it may allow you to turn up some other CPU dependant settings like display refresh rates etc while still maintaining the same frame rates.
SMT off on my 5900 gave me a noticable boost, interested in how it goes for you. What PBO setting did you use? I know that “default” is actually using PBO, did you manually activate it in a different profile? (I’m somewhat dumb with PBO and OC on Ryzen.)
With VR, 30 fps tends to be the realistic target to aim for, so CPU bottlenecking isn’t as big a thing.
I went from a 3600X to a 5800X with a 3080 using a Reverb G2, and the main advantage in VR I saw was being able to ramp up the level of detail settings all the way to 200. Also, it’s nice to not have to mess around shutting everything alse down, setting high priority etc.
Don’t assume you’re CPU bottlenecked just because the MSFS fps counter says you are MainThread bound - it seems to include motion smooting GPU time and will also ‘block’ if you’ve limited your fps in nvidia control panel or oculus tray tool for example.
If you’re using OpenXR (paritcularly with motion smoothing), use the OpenXR frame time counter to give you a bit more insight into what’s going on. You can probably do the same with fpsvr for steamvr or oculus dev tools.
It will only make a difference if you DON’T use reproduction. I was mainthread limited with a 3900x, my new 5800x is exactly the same. With reproduction off there was a benefit. Your 3070 is unlikely to make reproduction off much fun.
It’s a good upgrade, but if you’re hovering around 30fps, because of mainthread, with reproduction on, don’t expect it to get you past the magic number.

Thanks for the info guys. I consider myself lucky with the performance I’m getting which is hovering around 30fps with reprojection switched off with the custom render scale set to 65%. I’m also running at 100 TAA in game with most settings on high or ultra (windshield effects) with reflections and ambient occlusion switched off. LOD sliders are set to 150. I’m mostly gpu bound so I’m guessing it’s probably not worth the sizeable increase in cost for potentially little benefit.
