September 26, 20223 yr I currently have a 10900K @ 5.1GHz, 32GB RAM and 3090. I have 3 4K screens and the new multi-view set up. DLSS set to balanced. Running around 20-30 fps with FPS counter saying "Limit by CPU thread". Changing DLSS to performance makes no difference. I assume this means putting in a 4090 won't make a difference and I need a CPU upgrade? Maybe to the next Intel 13900K or AMD 7950X in a new PC? Edited September 26, 20223 yr by GodAtum

September 26, 20223 yr I don't think a CPU upgrade would yield more than a few percent more fps. Is your GPU working at 100%? Laminar Research customer -- Asobo/MS customer -- not an X-Aviation customer - or am I? 😉
September 27, 20223 yr Author Thanks for the replies. I've updated to the latest NVIDIA driver today and changed to DX12. Testing at KJFK. I had the terrain LOD slider at 200 with 21 fps. I reduced it to 100 at got 24 fps. Same result with 50. Looks like I'm limited by GPU so a 4090 might help? Edited September 27, 20223 yr by GodAtum
September 27, 20223 yr Don't forget that a 4090 may require a new Power Supply. Based on a number of YT and Internet reviews, you should have at least a 1000 watt ATX3.0 (yes 3.0 not 2.0) PS. ATX3.0 will give you native connectors as well as the ability to handle the large transient voltage spikes. A 1200 watt PS would be even better for future proofing (and depending on what CPU you are running). You may want to keep in mind the issue of melting power cables -- see Gigabyte x670 Aorus Elite AX MB; AMD 7800X3D CPU; Deepcool LT520 AIO Cooler; 64 Gb G.Skill Trident Z5 NEO DDR5 6000; Win11 Pro; P3D V5.4; 1 Samsung 990 2Tb NVMe SSD: 1 Crucial 4Tb MX500 SATA SSD; 1 Samsung 860 1Tb SSD; Gigabyte Aorus Extreme 1080ti 11Gb VRAM; Toshiba 43" LED TV @ 4k; Honeycomb Bravo.

My system is similar, except I have a 3080, and at similar settings (4K Ultra Preset DLSS performance) in a complex scenario (KLAX, PMDG 737) my GPU's frametime of 16 ms is around half my main thread frametime of 30 ms at that setting. Changing back to TAA still has me CPU limited and GPU frametime only goes up to 19ms. Either option gives me around 33 FPS and everywhere else simpler it is higher. Even my main thread frametime is 10 ms faster than yours, which is strange because the 10850K should be slightly slower than your 10900K. There is no way your 3090 should be delivering 3 times the frametime, which equates to 1/3 the performance, of my 3080. There is something wrong with your setup and I'd start by running a program like HwInfo to make sure your CPU and GPU are running at full speed when running MSFS.

Your only using 9.9GB of GPU memory upgrading your GPU will do very little you will be even more CPU bound, and for 2 grand you could upgrade you MB unless you have a Z690MB already and a 13900K and save money. A Z690 will take a 13900k and keep your DDR4 memory. CPU Bottleneck! This Scenario can cost you 50% FPS using a 3080 Ti (4770K, 6700K, 8700K vs 12900K) - YouTube Or if you are ok with waiting this may be better.

September 28, 20223 yr I found NO fps increase using DLSS Quality - probably because I'm mainthread limited. In your pic of the developer mode fps counter your GPU and mainthread frametimes are almost identical. In any case since they seem to be balanced I don't imagine you'd see much if any improvement regardless of which one you upgraded. Seems to me three 4k monitors are going to kill performance on ANY system. 3840 X 3 = 11,520 pixel width...NVIDIA spec shows "Maximum Digital Resolution = 7680 X 4320. i7-6700k • Gigabyte GA-Z170X-UD5 • 32GB DDR4 2666 • EVGA FTW ULTRA RTX3080 12GB

September 28, 20223 yr Get a 13900K with a 4090. You can pre order a system 2 weeks today. That’s what I’ll be doing. 64Gb DDR5 too. Liquid cooled.
