Hello, after downloading latest Pi, I hoped SS will be finally fixed, but besides that works better / improved performance still has artifacts ( good work ! )
This happens when around 44-46 FPS, like when working on edge of performance and when SS applies, deactivates - toggles. Artifacts are like bright geometriic shapes visible for 1-2 seconds every 5-10s.
This is not new, seems an old and known issue still not fixed yet, but frame gen. on SteamVR works as expected, so seems to me an issue in Pimax SW.
I see this mostly on MSFlight 2020 using OpenXR and Toolkit with DFR, but also on DCS native QuadView without toolkit ( but not so offem ).
I wanted to add a short video but attachment file unsupported on forum ( from IPhone )…

I read over internet that partial fix is to disable internal GPU in BIOS ( or Windows ) - I did and seems a bit better, but not gone. I tried HAGS ON/OFF, other settings but nothing works.
Everyone suggests to disable SS as solution, but I really want SS as improves smoothnes and gives 45/90FPS, but this artifacts ruines immersion.
We’ve been actively working on Smart Smoothing and have received valuable feedback from our closed-beta testers. Progress is ongoing, and the upcoming patch should be ready shortly after we address a few minor bugs.
Hello, after digging over internet for weeks ( issue seems to be for many months ) I finally manage to address the problem, actually thanks to Mbuccia PimaxXR ( great what he did to VR community ) 
the reason of this is latency/framerate → if I switch in PimaxXR option “prefer framerate over latency” all issues are gone ! this is a game changer. I tested on new 5090RTX in Flight Simulator 2020 and 2024 and the result is great. No sluttering, no artifacts - so if Pimax DEV can look at it, should be able to fix in not such a great effort.

For me that does not help; I still have artefacts, but unusually just sometimes, and that sometimes is when smart smoothing is switching between modes 45-33-60-45-60-33-45… FPS. And it is funny as I set my crystal to 90 Hz, it suppose never to go to 60 fps (should be or 90 fps native frames, or 45 fps smart smoothing).
I wish that we have switch for permanent 45 fps (45/90) smart smoothing, and if not achievable PE should just skip a frame, and not to go to lover 33/66 smart smoothing mode. Even 90 fps native frames should be never turned on.
PS: after switching smart smoothing once on and then off (with appy and restart), it was still active. I had to deselect and apply it several times.
ps: @pho3nix we booth were using Mbucchias PimaxXR, and not new official Pimax OpenXR…

Please also try update to Pimax beta 1.39.2 and SU2 Flight 2024 ( now should be official out of beta I suppose ) - i have updated everything to newest possible versions. For me FPS 45/90 is without artifacts anymore when SS ( on ) and half frame, almost 0 sluttering, please also set in Nvidia panel to prefer performance, I also have HAGS on.

Pimax I just downloaded newest Pimax 1.39.4 and Smart Smoothing is working GREAT ! In MS Flight 2024 and DCS ! I cannot believe my eyes, you finally did it - thanks ! With older versions I had turning off/on SS each couple of seconds and effect was really poor, even GPU handled 45-46 fps didnt see a fluent image, but now I fly over couple of minutes in DCS Syria, or Flight24 NY and almost all the time seen smoothed image 90 FPS ( SS from 45 FPS ) - Great JOB !
