Brief description of the issue:
Performance of the title has steadily gotten worse over the updates. I have tested the sim vanilla with ultra preset, both DX11 and 12. Getting sub 40-30fps in major and medium sized cities and airports with a pretty good system, and a fresh installation of W11
My test scenario is:
Ultra graphics preset.
Midday, livewx off
KJFK 31R straight ahead dep, climb to 5000ft, and observe the lod and performance, sim is vanilla and just a few airplanes installed from marketplace to test performance of different addons, all premium deluxe content + WU’s are installed on an Nvme drive.
test results. Nearly 90% of the time the sim is Main thread limited, with hwmonitor showing cpu being poorly utilized and showing loads primarily on one core.
DLSS 3 frame gen somewhat helps the perf. but it also takes away some cpu time and induces input lag.
Results:
Default A320 53fps on ground, 30-40 on takeoff roll, in air 60-80
WT 747, 44 ground, 27-32 takeoff, air 45-50
Hjet from marketplace, 41 ground, 28-35 takeoff, air 50
Ini 310, 37 on ground, 27-30 on takeoff, air 47
Also terrain textures and photogrammetry lod starts to get blurry allready at 1000-3000ft, so to get any good looking terrain textures we need to bump up the terrain lod, which in turn worsens the performance.

Taken at 5000ft just off KJFK 31R
