Nvidia Image Scaling NIS and VR

In other dev updates, I’m putting the finishing touch on an installer program! It works… except for the uninstall part! But hey, who would want to uninstall this software anyway :sweat_smile:

NVIDIA released today NIS 1.0.1, and the changelog includes performance optimizations. I’ll be sure to upgrade to 1.0.1 as soon as I can!

Woohooo :sign_of_the_horns::heart_eyes:

Thanks very much to all involved, I’ll check all this out over the next few days.

Im having solid 45fps without stuttering and without motion repro. Mut scenery has ghosts everywhere, for example smoke pipes in rooftops i can see double, like after 10 shots of vodka. Is that normal? Need still more fps?

where can i download that and where can i make a setup for nsi ?
i install the tool. ut the effect is bad and not good and i think i have a problem with my install
i can make with strg f1 on and off i think thats right but the effect is bad

What are your settings, what is your hardware?

OpenXR dev tool, MSFS Renderscale, FS2020.cfg?

i have the quest 2 and can not take the openxr tool
the render is 2100x2100 and fs2020 is 0.7 0.2

hello,
how do you can take the openxr software with the oculus ?
i have the quest 2 and cant take the openxr software
pls can you give me more infos ?
thx

If you’re having difficulties at this time I suggest you wait until the beta release., which will offer a simpler install process.

(Also I cannot answer because I don’t have an oculus device)

I’ve posted ITT i wasn’t getting much gains (2-3fps) with a pimax 8kx (steamvr) but i’ve just tried alpha 4 for the 1st time and i’m getting a solid 6-7fps extra (fs2020.cfg is 0.8/0.2). Very pleased.

Added a blurb to the description indicating DX11 only. I’ve never used DX12 because it breaks my DC-6.

If anyone has a similar setup, can you tell me what you are running the Quest 2 resolution at in the desktop app?
5950x
3080 Ti
32gb Ram.

And what settings are you running in this new API and MSFS ? Thanks!!

I have similar setup and always used max resolution in the app. Still experimenting with the API, I put my results a few posts above

playing with contrast, brightness and saturation would be the holy graal for this game in VR. It needs exactly that, so much…
So there is hope, at least!
thank you!

@DerKlausi - yes it should be possible. The NIS scaler code I wrote is a proof of concept of inserting a shader between the application and OpenXR. This shader could be anything, including what you mentioned for contrast etc. For example we could include this shader: Brightness, contrast, saturation (shadertoy.com)

Thanks! So you are on max in quest app 5408x2736?

This is further down my To-do list, but nonetheless it’s on it! We in theory have all the hooks in place now in this NIS layer, and it’s possible to add post-processing. The 2 main difficulties are: 1) how much will it cost in performance (I am not experienced at writing efficient shaders) and 2) how do we make this easily configurable (we want to be able to tweak these in-game but save the settings). Doing the experiments for 1) is not too hard, but then the concept of 2) needs more thinking…

PS: The To-do list in question, btw: XR_APILAYER_NOVENDOR_nis_scaler/TODO at main · mbucchia/XR_APILAYER_NOVENDOR_nis_scaler (github.com)

my rig is 11900K (5.1), 3090 (450w), 128RAM 3200CL15, Nvme ssd, G2. Rendring:100/100 NIS: .8/.2 most high/ultra lod:200/150 fps locked 30, nvidia drv 497.09
I have sudden drops fps to 25 even at high altitude. 30 fps is not stable despite the fact that the GPU load does not exceed 80%. I think the bottleneck is the CPU, because the message “main thread” often appears or it’s something else in settings.

I think those are very CUP-intensive settings. Try 100/100 and see if you get GPU utilization higher and more stable FPS. I have 3080 on 5900X, which is not that far from your configuration, and I know I have a stuttery mess if I try 200/150, probably due to CPU.
