August 8, 20214 yr Since the hotfix, the sim has been running better than ever for me. However, I've seen a number of posts where users mention that their CPU and GPU resources are grossly under-used and that is the same for me. I also receive the "Limited by Main Thread" notification - on average, the sim is now using about 16% of my CPU resources and about 29% of my GPU, wasting a ton of my resource capability (and I have an older system). Is this main thread bottleneck something that will be removed in the future? Randall Rocke
August 8, 20214 yr Are you running FPS unlimited? Do you open resorce monitor to see whats happening on all cores? You dont say what CPU or GPU is? Edited August 8, 20214 yr by Nyxx David Murden.

August 8, 20214 yr My GPU is pegged at 99% - 100% all the time in MSFS. But it only uses 4 out of 24 threads of my CPU.

Strange, isn't the game optimized for AMD considering the Xbox? all 20 threads are in use on my 10900k since SU5.

I still keep a temperature monitor on screen, which also shows FPS, but it is really an afterthought.

I've got my FPS capped at 60 (in sim) and v-synced. I get a constant 30 FPS almost everywhere with the current settings and all is smooth - stuttering and/or freezes are very rare. I haven't opened resource monitor in-flight as I've been only measuring with the Dev system to make certain I'm checking sim performance. I only run Developer mode occasionally to check the latest performance and I do not leave it running. I'll give Resource Monitor a go in the next flight. CPU is Intel i7-2600 @ 3.40GHz; GPU is RTX 2060 Super Randall Rocke

I am pleased - and when I look side to side (so far) I haven't had any performance issues. Guess I'll need to check the resource monitors while doing that and see what's happening. 🙂 Randall Rocke

I have always used that in the past, but since moving to an HDR monitor last week, I have found that there is an annoying flicker in lighting intensity with any mouse movement when the game bar performance tab is present on the screen. Just occurred to me as I write this, that I might be able to move the perf window to my second monitor - never thought to try that before...
