OK, finally. I can report the first perfect flight with my Quest 3. Munich to Zurich in Mitsubishi MU-2. Wanted to do a regular flight in a fairly busy area with photogrammetry but not too much over the top like JFK. Incredibly smooth, no recurring stutters, like regular repeating stutters that I couldn’t get rid of in my Reverb G2. The scenery was incredibly smooth. Of course, there were several single stutters on scenery loading (probably) but those are unavoidable, and there were just a few during an hour-long flight. The entire experience felt great. There were a few moments when the cockpit movement was not entirely smooth when turning my head, though scenery was always smooth. That problem is still a puzzle for me, but even this was minimal on that flight, easy to ignore, because 99% of the time everything was totally smooth. Looks like there were enough overhead that I didn’t see any noticeable SSW warping artifacts.
So here’s my setting, if anyone wants to try those.
Hardware: Quest 3 (v62), RTX4090, 7950X3D, 64Gb DDR5 RAM, 4x NVMe SSDs (Dedicated Win10 boot for gaming + MSFS on a fast SSD).
Windows: Game mode = off, HAGS = on, 8Gb RAM Drive for MSFS rolling cache.
RTX4090: Nvidia driver 537.42. Control Panel is mostly default, power is set to performance, and texture filtering is set to performance too.
Virtual Desktop: Godlike mode, AV1 130 gbps, 80Hz, SSW = “always on”. Sharpening = 40%. Controller passthrough = on - hand tracking totally works! I can switch laser/direct mode, operate switches and buttons by pinching etc. - very handy, so I don’t have to blindly search for a controller when I need to do something in the cockpit that’s not covered by my hardware.
OpenXR Toolkit: Override resolution = yes, ~3678 x ~3150 or thereabouts (per eye). This comes on top of the Godlike mode that renders at 3840x2160 pixels (both eyes). Remove black mask = on. Foveated Rendering = on, Quality / Wide. Sharpening = CAS 100. Turbo = on. This was a surprise because it is noticeably smoother and despite the warning that it breaks Motion Reprojection, it doesn’t seem to. I must have MR because without it the cockpit motion is kind of juddery/blurry. I’m sensitive to the judders and can’t stand locked 40FPS without MR even at 120Hz (I tried today - nope, not my cup of tea).
RTSS - locked at 41FPS.
MSFS - TAA 100%, TLOD 105, OLOD 100 (it helps to reduce TLOD on the ground and during landing and reduce OLOD at altitude, also drop clouds one level if FPS drops or on the ground, there are ways to do those things…), Clouds = High, car traffic = 20, a mix of Medium and High settings - mostly High, with Grass and Buildings on Medium. Ambient Occlusion = Low.
Nvidia reduce latency = On+Boost. MSFS Motion Reprojection - I’m not sure about that one. This flight was off, but I tried on. Not sure if it does anything really. Some say it smoothens the cockpit movement, but I don’t think so. Sharpening at 0 - OXRTK does better sharpening IMHO, and VD does some too. I think only doing VD sharpening is not as good and too obvious.
I think that’s it.
