I had the same 30%-40% loss with TAA upon release. But magically the Day the first Hotfix Patch arrived my TAA Performance was back on par with fs2020 with just minor adjustments to the settings. However yesterday the Performance was suddenly bad again without changing settings, flying in the same area with the same aircraft. When Performance is low i can see a lot of periodical red spikes in the Steam VR Performance Monitor ( like 5 per second). So i saw a great performance of 2024 with TAA already which gives me hope it is a bug that gets sorted out soon. Ill try again tonight as yesterday was sunday and the Servers where slow. i cannot imagine Bandwidth has an impact on FPS, but who knows… some already suspected Server performance as the culprit.
UPDATE: Today again performance was on the bad side. When performance was good the other day i could tune settings like TAA RenderScale to optimize. Today Renderscale simply did not apply. Crank it up to 200 or drop it to 30. No difference in Frametimes and no visual difference. And no difference to apply in flight or Mainmenu. Only Sim restart made the Renderscale apply.
The VR-Setting Screen is bugged/fake, you cannot disable Terrain Shadows too and some settings show “undefined” until you change a value. Wouldn’t be surprised if simply the whole VR-Graphic Settings are not working like expected. Maybe get mixed with 2D settings or labels and inputs got mixed up.
oh boy…
