Again for comparison.
31-01 v4.1 Test, empty (!) image, full-screen, locked, LoS enabled, Lighting enabled:
WoW Shadowlands, Heart of the Forrest, Hearthstone spawn-point, 0° looking towards wall, Quality 10 (maximum!) + CMAA:

Again: any more information needed?

Another comparison to better judge the proportions of GPU load on my system:
31-01 v4.1 Test, empty (!) image, full-screen, locked, LoS enabled, Lighting enabled:
WoW, Shadowlands, maximum (!) settings + CMAA:

Quick test on my system :
no FGU GPU 24% CPU 5%
FGU on, start page 24% 8%
FGU campaign on, no image 24% 6%
FGU campaign on, no los, no light 24% 8%
FGU campaign on, los on, no light 29% 6%
FGU campaign on, los on, lights on 35% 8% vsync 0
FGU campaign on, los on, lights on 100% 10% vsync 1
FGU campaign on, los on, lights on 97% 10% vsync 2
FGU campaign on, los on, lights on 96% 10% vsync 3
FGU campaign on, los on, lights on 96% 10% vsync 4
RTX 2070 super, ryzen 9 3900x, 24 different lights on + light on token
So 6% more than los alone and 11% more than no light + no los.
The real dealbreaker here is vsync. I keep it at 0.

VSync 0 is not the same as VSync on/1, though. But great find, because it should give the developers a good clue on where to look for the culprit. Thanks for that!
PS: I don't seem to measure a difference between 0 and 1, while 2-4 lower GPU load. Tested with an empty image. Let's see what the next version brings, since several people reported the same problems now.Last edited by Weissrolf; April 5th, 2021 at 13:45.

Tried "/vsync on" and "/vsync off". Both leads to "Video Sync Rate is 1".

yes, 0 = fixed 60 fps, 1 = match OS frame rate, 2 = half OS frame rate, 3 = third OS frame rate, 4 = quarter OS frame rate. I don't know what is my "OS frame rate" though. Could be interesting to find it. It is probably way higher than 60.

your OS frame rate varies
looking at these numbers
it would seem that your OS frame rate is likely a lot higher

You may be using a 144 Hz oder 240 Hz display. Anyway, even at 60 fps the GPU load of FGU is too high for what it does (literally nothing on a blank image).
