One cool thing I immediately noticed that has been fixed in SU5 is that there are now red blinking obstruction lights. The floating yellow lights over wind turbines had also been fixed and replaced with red blinking obstruction lights. Other obstructions had red solid lights depending on height which I believe was all done to specifications as in real life. So much better for night flying! I only saw this at one place in the US so I have not checked other areas but this was a welcome and undocumented change since I had reported the floating yellow lights multiple sim updates before.

I lost frames when I tested in VR as well yesterday and could see no perceivable difference in smoothness with SM on or off. I see in other posts that he is getting the fps display on the 2d monitor. I don't believe this is reflective of the fps in VR which was also one of the reasons it was noted that this didn't work in VR in the past. I really don't think it actually works in VR as if it did and caused this kind of performance increase it would be all over the internet. I have an i9 11900k and a RTX4090 and have gotten my best performance lately with the new DLSS 4.5 and Preset M on Performance mode. I also have my resolution in Pimax play turned down to 90%. That is giving me about 40fps and very smooth flight even in complex aircraft unless I am around a high detail large airport + photogrammetry area. Unfortunately for me I am not seeing a benefit and will likely turn HAGS back off as I am now experiencing some judder in the headset after turning it on to test SM. However I don't know yet if it's HAGS or the updated Pimax Play software causing that issue.

I tried turning on smooth motion in VR on my Pimax Crystal light and saw no difference in perceived smoothness either way. FPS was also the same (which I would expect because these are perceived doubled frames so I would assume the fps counter is not going to be higher. Anyway I see no difference just as I have in the past in VR. I don’t know if I am doing something wrong but as before it does not seem to actually work in VR. All I did was turn on HAGS and the activated smooth motion for MSFS2024 in the NVIDIA app.

It is hard to understand but it also may not be that simple or they probably would have done it. And since all of the Photogrammetry fixes that 3rd parties do are for small areas and have to be done by hand I can see why they haven't tackled it. Not saying it's great but maybe the AI isn't that good? How does it differentiate between a tree blob and other blobs? It would be awesome if it worked but I think this is a limitation of the way it works in the sim.

Maybe it’s a design decision because the leafy trees (even the colored ones) are hiding the photogrammetry blob trees. If you use trees where the leaves are falling off then you’re not hiding the blobs anymore and it looks like crud. Maybe they decided to keep hiding them as the fall colors fade and leaves are supposed to drop.

Tested this out myself today with the Pimax Crystal Light. I saw no performance improvement or any noticeable changes when turning motion smoothing on in VR. The VR mirror on my PC was noticeably smoother however. I tried a recording in OBS however the recording looked the same as in my headset which makes sense because I remember that I am using an OBS plugin that captures the OpenXR view and is not just a mirror capture. I can see where this might be useful if you’re capturing your mirror or you want it to be smooth for someone watching your screen. However it does nothing for you in your VR headset to make the experience better. I’ve also rolled back to NVIDIA Driver version 577.00 because I started getting graphics card errors (no crashes though) with the 580 drivers and my 4090. This continued with the latest 580 driver today when I updated to try this motion smoothing out.

Everything I am reading says this does not work to increase VR performance and I can’t find the text you originally posted anywhere else where it says: NVIDIA Smooth Motion is a driver-based feature that generates interpolated frames to improve visual smoothness, especially in VR, All I have been able to find is a YouTube video where he shows that it helps performance in the VR mirror for recording. Everything else I have read says it’s not supposed to work in VR?

Calvin, While it’s way better the issue is still not resolved. Had 2 other flights now with the same jittering issue but a lot less frequent. Also noticed if I placed my fingers over the top cameras it would quit. May go back to tape if this continues as it seemed to not happen at all with the tape over the cameras.

2024 - SU3 Beta latest version

So far after multiple flights it appears to have been resolved with the latest Pimax Play for me. I no longer have the tape on my headset and have not experienced the juddering at all.

I’m also using latest SU3 Beta with 2024 so I’m not sure I’m the best to compare with.

Well in 2 flights last night I didn’t have the issue and didn’t change anything with my tape on the headset and still on latest Pimax Play. I did experiment with various graphics settings and TAA vs DLSS and Textures between High and Medium. With my 4090 in TAA and textures High I got bad performance and the pop up asking me to lower settings. On this build I’ve settled on DLSS Quality and Textures at High (VRAM was only about 3% different between the 2. This was tested in San Diego a known hard performance area and the Miltech MH-60. I was getting around 30fps in VR. Flying outside of town away from the details I could get 38-40fps and at no time experienced the jitter in the headset. This was all MSFS2024. I am not using 2020.

Hmmm, ok. I was still getting the same issues in the headset last night with the tape on but maybe with the updated dll file I need to try it with tape off. I will do a deep dive this weekend checking performance with the new SU3 and do some experimenting. If I need to I will contact support.

Did the new .dll file come with the latest 1.41 update? If so I saw no improvement with the tape off the Crystal Light so I put the tape back on. That being said I also tried the new SU3 beta update tonight which improves performance in heavy areas and I could see it for sure with reduced sim stuttering especially when looking around. I had fps of 36-40 in San Diego which is way better. However even with the tape on I started suffering from the jittering again with fps still 36-40. If the new DLL file does not come with 1.41 then I will contact support.

Hmmmm….it stopped working for me on 1.5.23 (SU3 Beta) and won’t connect. I am also on the latest app version.
