March 18, 20224 yr I have Quest 2, RTX 3090, 9900K, and I'm wondering how much I can benefit from upgrading to 12900K. Is the CPU also my bottleneck with my setup?
March 19, 20224 yr You can get a rough idea of the improvement you can expect in MSFS from this video here Comparing 5 Generations of Intel i7 Processors! 12700K vs 11700K vs 10700K vs 9700K vs 8700K. It's a pity they don't show a 4K test result, as it would be more representative of what graphics load your Quest 2 puts on your system, but even at 1440p, a 12th gen i7 would only give an 8% FPS improvement over a 9th gen i7 and would be lower at the higher resolution VR normally runs at. The best thing to do is to use developer mode FPS view under various situations in which you normally fly and see what that tells you. You'd have to be generally main thread limited most of the time before it would start to be worth the CPU upgrade. In my experience with my system, which has a newer i9, slower 3080 and slightly higher res G2, I am pretty much GPU limited in all flight scenarios by a long shot, so upgrading my CPU would be a waste of time. 9800X3D | 4090 | 64GB | 2+1TB NVME | 2TB SSD | 2TB HDD | 85/50/43” TVs | Quest 3 | DOF H3 Motion Rig | Buttkicker | T.16000M Flight Kit MSFS @ 4K Ultra DLSS Performance FG 80 FPS | VR VDXR Godlike 80Hz SSW | MSFS VR DLSS Quality, Ultra Preset - Windows 11 Acer Nitro 5 | i5-11400H | RTX 3060 6 GB | 32GB DDR4 | 15.6" FHD IPS 144Hz | 2 x 512 GB SSD | Windows 11
March 19, 20224 yr As you are running in VR, I would say that your CPU Is still up to the task. In 4K I would be sure that this is the case.

March 19, 20224 yr my understanding from a very early Asobo press conference is: throw your money first & foremost at the best GPU you can afford, in other words: GPU is king. most of MSFS code runs on the GPU, not just the graphics. Asobo makes intensive use of GPU programming which allows massive parallel execution of code segments, that is why we see 99% GPU load even on the fastest RTX 3090, much more than P3D/xplane. otherwise we wouldn't see the performance in MSFS that we do see, including the best graphics of all flight simulators. if you are interested to increase your overall performance, perhaps wait for the RTX 4000 generation (supposedly up to 2x performance of RTX 3090). but mostly required only for 4K/VR resolution. A 500 watt PSU won't cut it though. https://www.cherryservers.com/blog/introduction-to-gpu-programming-with-cuda-and-python Edited March 19, 20224 yr by turbomax AMD 7800X3D, Windows 11, Gigabyte X670 AORUS Elite AX Motherboard, 64GB DDR5 G.SKILL Trident Z5 NEO RGB (AMD Expo), RTX 4090, Samsung 980 PRO M.2 NVMe SSD 2 TB PCIe 4.0, Samsung 980 PRO M.2 NVMe SSD 1 TB PCIe 4.0, 4K resolution 50" TV @60Hz, VR: Pimax Crystal Light + HP Reverb G2 @ 90 Hz, Honeycomb Bravo Throttle Quadrant, be quiet 1000W PSU, Noctua NH-U12S chromax.black air cooler. 60-130 fps. no CPU overclocking. very nice.
