I’m enjoying my ultrawide Alienware OLED for flight sim purposes quite well. I have VR for doing some VFR flying but for anything with instruments I like to keep it basic and 2D.
To add to that, I think HDR actually makes a good difference flying at night and dusk. It makes it much more enjoyable. A lot of VR panels still struggle with halos and other visual artifacts on dark scenes with highlights like runway lights.
Isn't that curve a bit tight for that distance? It makes sense as an immersive, close monitor, but if you have it far away behind a wheel, it's going to be distorted.
I have an Odyssey g9 and it has a 1000R curve - and sits about 3 feet from my face and that feels about right. At a guess - at 800R it is a bit too tight to sit far enough away to have a proper wheel and such in between you and the display.
