Zotac Trinity OC LHR RTX 3080 nVidia 512.15 DCH running a Samsung g5 3440x1440 on DPIt's quite normal that you don't get the same performance in every situation.
The guy who was called a liar in this discussion claimed that he gets 120 FPS in the concourse with his RTX3080, so I assumed that was the benchmark.
I get ~100 FPS in the concourse with my RTX3070 in ultra/1440p so I believe him.
MSI z-690 Edge wi-fi DDR4
i7 12700k (no manual overclock, just the single core boost at 5ghz)
32Gb Team Group 8Pack Edition Dark Pro C16 3600 (XMP 1)
Windaz 10 Pro
Samsung 980 Pro 500GB PCI-ex4 NVMe +WD Black SN850 1TB NVMe PCI-ex4 (these have nowt to do with how the game plays, just how fast the game loads)
No crap installed whatsover, Just windows, all updates, Target software for my Warthog and vJoy for Joystick Curves and all the latest drivers.
If that lot did not run Odyssey smoothly and run stable then I would personally contact Frontier and tell them that it really does need a good and thorough optimising and everybody is correct in it running poorly on RTX cards.
A 3070 or 3080 and the right setup and a none bloated windows install is more than capable of running Odyssey smoothly.
