Still love cas sharpening and sunglasses

Sunglasses should really be a native option in the sim by now!

OK, did some testing just now.
Pimax Crystal, 5800x3D, 4090, Win 10, 32GB ram.
At full native resolution on DLSS Quality I was getting 40fps with DFR on set to Quality Wide. With DFR off I got 37fps. Changing to performance wide or narrow made no difference.
So I decided to exit the sim and turn off the Toolkit. But then I ran into major problems in VR. I kept getting very high Render Thread times and FPS tanked to 15 or so. Multiple restarts of sim and even PC did not fix it. Sim runs fine in 2D, just VR is borked without the Toolkit
If I turn the Toolkit on again it goes away and everything works fine again.
See screenshot below with Toolkit disabled. Render thread is hard to read but is 65.4 ms.
Any ideas how to fix this?
Kinda close to me although I did not turn off the toolkit. I think my averages were about the same with better peaks with DFR.
I’d guess turning it off may have left a bad setting in the registry?
By full native resolution, do you mean no upscaling in OpenXR Toolkit?
Managed to fix the framerate tanking with the Toolkit off, though not sure how, lol. It came back again once, but then it stopped.
No idea if there is a possible bad setting in the registry causing this, will have to see what mbucchia says.
By native resolution of the headset, I mean the default high setting in the PimaxPlay client, i.e, 4312 * 5102 as shown in the Toolkit. If you select Resolution Override in the Toolkit to off that’s the resolution you get.
If you disable OpenXR Toolkit then none of the things it left in the registry matters.
I’m not really sure what could be your issue. Are you using PimaxXR or Pimax’s own OpenXR runtime?
I’m on OpenXR, don’t trust going to PimaxXR just yet. Reports are performance tanks on PimaxXR.
Strange, I think I’ve read in several places (including this very forum) that my original PimaxXR still outperformed Pimax’s own OpenXR implementation.
Re: foveated rendering low improvements, my best guess is it means the heuristic to detect render passes just doesnt work well in 2024, leading to a low “VRS RTV”, see the last part of that post

Well, haven’t you also worked on SpaceX’s Dragon capsule’s software systems? Way more impressive!
I’m using OpenXR runtime, with PimaxXR selected in your OpenXR control centre. I remember seeing your post obove that Pimax own version is not as good.
Men you did an amazing thing.
Even 2024 runs better with youre toolkit then 2024 by itself. Really ashame you stopped.
Cant believe that Asobo is still at youre level.
Cas and sunglasses and other are still great.
If you ever go for a paid version I think you will have a lot of support.
So thks again!!
Still using the toolkit. CAS makes DLSS bearable for me,the in-game sharpening is not as good. Also it’s better to have the possibility to ovverride the resolution in the headest directly. QOL.
Thanks again Matthieu, I don’t think I could use FS2024 without the toolkit.
I use it with no problem at all. It works well, and tracks my eyes without issue. I have it at 50% 1/4 res and the contour is barely noticeable on the crystal.
Isn’t there a CAS setting in the sim itself? A sharpening slider 0-200? That is exactly the same as OpenXR Toolkit CAS as far as I remember.

I do not think it does the same job or CAS from the tool kit acts as a multiplier, I don’t know. I just try things. When I use the in game sharpening to the max, it still looks blurry. If I add CAS from the toolkit on top of that, it looks a lot sharper. I don’t know or understand why, but there is a significant difference in clarity. Also, yes, your pimaxXR does out-perform the pimax version. I just spent 2 days testing on the pimax version and just returned to yours. Significant difference on that front too. I have a motion platform, so unfortunately I feel the stutter more than I see them. I have a lot less interruption with your implementation.
I consistently lock on 45fps at 3750 x XXXX. CAS at 100%, in game sharp at 200, DLSS on quality. locked to 1/2 frame rate in PIMAX XR. It s a decent experience. I don’t really fly over busy city and I fly the blacksquare duke mostly
Pimax Crystal OG, i9-13900k, 4090, 64gb ram
~3% only in most cases. Seemingly less than it used to.
For me CAS is way better than what VD or MSFS provides. That 0-200 slider doesn’t work well for me but CAS at 75-89% is good.
Pico4, 7900XTX.
Where do you set the slider in the sim when using CAS?
I’m saying OpenXR Tookit CAS is better than the others.
It’s strange, it should really be the same. Are you setting both sharpening in MSFS and OpenXR Toolkit simultaneously? Once thing we’ve observed with DCS was that double-sharpening was bad, due to ringing (causes shimmering).
Thanks for sharing.
Edit: other user above mentioned maxing out both sharpening. This is very weird as doing that in the other sim was actually deteriorating.
