msfs VR fps mod

[tyke1 30]

This is from a thread on msfs forums right now, its a mod that adds 10-15fps. Currently only works for WMR headsets like G2 but the modder (mbucchia) is working on a SteamVR fix. It adds Nvidia NIS.

Anyone tried it? To gain FPS you’d need to render at lower res and have NIS rebuild the pixels

 

edit: ok, i’ve checked this out and it looks very useful. Written by a microsoft employee, openxr dev as a personal project. It takes the openxr scaling and applies 70% (configurable) downscale and then seeks to restore sharpness with 50% NIS

The modder has just added alpha version 3 which works with steamvr using headsets. Ive tested it with mine (pimax), it gave 2-3fps with a slightly more blurred image. YMMV as some seem to be getting 10 fps.

Only issue is nis upconvert at low light situations (dusk, dawn, night) seems to reduce the color depth and see texture banding in clouds etc. for some reason.

I did not try yet at night.

But I'm very happy with this shader mod, I never had before so much clarity and performance-smoothness 🙂

I've replaced OXR scale 70% by NIS 0.75 and its' much much better!

Using the default settings the textures are definitely crisper but artefacts and shimmering around objects once airborne. Maybe I need to play with the settings a little.

[roland_lfor 245]

You might try with sharpness=0.0, and set only the scale.

[mobeans10 197]

Thanks. Will give that a try.

Tried setting the sharpness to zero. Objects are still too noisy for my liking and the night time clouds are, let's just say, not good.

It's a Work In Progress, see the thread on the official forums for better discussion.

Understood. Definitely some potential here.

Alpha4 is now out which appears to have fixed the night-time cloud issues.

[kdfw__ 542]

yup, a4 night time clouds look good now.

I've got solid 7 or 8 fps gains with it (steam vr) scaling 0.8 sharpness 0.2

It works for me, and I gain several fps when flying most locations, but it seems to perform worse (than not installing it) when flying in New York City where I get better clarity and fps uninstalling it. It's odd.

I normally fly with all airport traffic at 100%, but dropping it back to around 50% has cured it. Now as good as other locations 👍
