Really glad I'm not going through the waiting/fingernail biting like you guys are.
Well done B12, at getting a 3090, and Donka, I hope a 6800XT has your name on it soon.
The latest updates for P3Dv5.1 HF and MSFS are working really well with my old 8Gb GTX 1080 - solid 30 fps in both MSFS and P3D (easy 60 fps if not limited to 30) with World sliders fully maxed (P3D) and 4K Custom Ultra in MSFS - all scenery detail maxed but all 'Junk' settings off or min - eg no Lens Flare, Window effects, Icing etc. In P3D I now only fly in TE HD regions plus AUv2 and NZ and find this as graphically satisfying as MSFS. Plus I have all my high detail planes. So, still mostly P3D for me.
I'll wait for supply to ease in the New Year, and get a 6800XT which will cure my graphics bottleneck.
Some YouTubes show that the 3080 and 3090, at 4K Ultra do a bit better in MSFS than the 6800XT, but the difference is minor. Having 16 Gb VRAM is what I'm after, and is more important to me than a frame or 2.
Of course, B12, you are laughing with 24 Gb. I know why nVidia is green - the colour of abject jealousy!
Keep posting, guys, I'm enjoying it all.
