Scenery is fine, not sure why you ask this.
Obviously, depending where I fly (more or less GPU demanding) I can switch between DLSS Quality and DLSS Balanced. Obviously the picture quality is better on DLSS Quality, but still fine on Balanced. Note I’m more than “Vanilla” on Quest 3 settings as I just recently received it, so I didn’t do any “tricks” to get a better image (for now). I just use the sim settings, didn’t touch anything outside (SteamVR, etc.). Only very few Virtual Desktop settings (like SpaceWarp to Always ON instead of default “Automatic”), and Streaming Fps to 80 (instead of default 90).
