Still can't seem to get what I'd call a god-ray - but am I bovverred?!?!? Not at all. Just started a race a 6AM at LM, clear skies, 15th or so position, Ultra preset, 25 visible vehicles etc. - and although (again) the fps on the grid dipped to 60fps in the rolling start, it rose quickly to 70s, 80s and 90 during the first lap as the pack spread out a bit and the visual quality compared to what I was running is amazing.
So for the record, I'm currently running:
OpenXR toolkit v1.3.8 (Turbo mode, CAS @ 125% resolution, Foveated rendering @ Quality preset (if that does anything in a HP G2))
i9-13900K (2 cores @ 61x, 2@58x, rest at 56x)
Gigabyte Aorus Master 4090 (Afterburner settings - 2550Mhz GPU, 11941 MEM, +5% core voltage, +283MHz core clock, +1441MHz memory, 133% power limit)
Nvidia 572.60 driver
LMU:
Windowed @ 1600x1024 (no VR mirror!)
Post effects - High
FSAA - MSAA 4x
FXAA on
Preset Ultra (everything Ultra except Opponent Detail High, Shadow Blur QUality, Soft particles High, Rain High)
