New fsr mod that enables you to use nvidias new upscaling algorithm

[radiantglow]

tried the new file fsholger released on GitHub today that enables you to use Nvidias NIS and it worked great, better FPS and imo better graphic fidelity than FSR provided!

Link to the new openvr-fsr:

https://github.com/fholger/openvr_fsr/releases/tag/fsr_v2.0

[javelina]

I downloaded this yesterday for the other sim.  I'm planning to use it with IL-2 tomorrow, unfortunately can't fly today.  Looking forward to seeing how this works out.  fsholger's mod has really worked out great for me.  thanks for the post!

[Giovanni_Giorgio]

Good stuff! Definitely worth trying.

[Tatzlwurm]

Downloaded today, got very good results, everything runs smooth and high image quality.

I maxed antialiasing wich normaly kills my framerate.

 

I got 1070ti and reverb g2.

 

I say its a must.

Download openvr_fsr_v2.0.zip
In your bin\game\ folder rename the original openvr_api.dll file as something else just in case you want to revert back
Unzip the openvr_fsr_v2.0.zip to bin\game\
Open up openvr_mod.cfg and amend the settings 
Launch the game.

The default .cfg file contains all the parameters:

Is this good for a G2 running a 3080?

[Knarlfin]

I'm running it with a G2 and a 3080, still messing about with the in game settings but have it set to those default numbers in FSR.

Thanks. What are you running in IL2? Ultra?

 

Its like looking through a fish eye. It really strains my eyes. Are there any adjustments?

Edited November 23, 2021 by CDRSEABEE

[Knarlfin]

It's in Ultra, I think the renderscale = 0.77 in FSR forces it.

For fisheye try checking the Resolution in WMR is set to "Automatic upscaling (best performance)".  Not "4320 x 2160 (best quality)".

The only other thing I can think of is getting your IPD correct, either see an optician or measure it with a tape measure in a mirror!  It's easy to knock the slider on the G2 and you don't always know you've done it.
 

[[CPT]Crunch]

The presets are for AMD, Nividia can use any number in the given range and it'll work, can't speak for AMD.  But if you use 1 itself the sharpen filter will be disabled/off, kind of making use of this pointless.  I use 1.01 for no downscaling and filter on.  Also set the radius rather small, turn on the debugmode true, and use the in game IPD key commands to set your true in game correction for the G-2 by perfectly overlapping the horizontal with the given image outer circles.  Once the correction % is set forget about them forever and turn the debug mode back off.  Relieves the misalignment most of the G-2's suffer from, at least in the horizontal.

Fish eye problem for me was a Headset display option, under windows mixed reality settings.  Anything other than "best visual quality" gives me fish eye problems like you describe.

Yep. I fixed it. Thanks

Hi

After the 4.701 version update, AMD's FSR sharpening is no longer valid

[firdimigdi]

Not seeing this here. Make sure that openvr_api.dll was not overwritten with the default one after the update.

This seems to be true, maybe not for all. I tried all the different fsr/nis settings through openvr_mod.cfg, from the absolute lowest to the highest. Checked integrity of gamefiles, downloaded original openvr_api.dll and replaced with fholgers 2.0. there is no difference. I also downloaded the latest 497.09 drivers if that somehow should be the case, but no. Seems like its not working ?‍♂️

 

 

 

Update : I checked openvr_mod.log and something was off, it wasn't injecting. I replaced my custom openvr_mod.cfg and typed in my old values to the original as well, that seemed to do the trick ?‍♂️. Be sure to check that =GW=501Railgun

Does the double sharpening with the mod and then in the game make any real difference, or better to desactivate the one in the game if using sharpening through the mod?

Sharpening using NIS works, but is not as clear as AMD's FSR......

Both works, check your openvr_mod.log to be sure. You can always delete the log file so you get a new one.

NIS should give you a clearer image than fsr, experiment with sharpness, dont need much.

If its not working you'll see something like this

Requested interface IVRSystem_015
Requested interface IVRCompositor_020

And not much more.

If its working, it should look like something like this.

You can use both together but ingame sharpen costs a little performance. Together it will get oversharpened and look quite bad. Better to stick to fsr or nis only sharpen. If you still want to use both together, go down on the fsr/nis sharpen.

Which option is better, FSR or NIS?

[SCG_Fenris_Wolf]

I tested it today.

 

NIS is largely superior with my config. Much less rasters to see.

 

I ran the Reverb G2 at 3160x3100 target, upscaled, from 2430x2377 using 0.77 NIS. NIS Sharpen at 0.9, Post-Sharpen-Ingame disabled, no FXAA/MSAA needed.

 

It looked 4K and ran at 90Hz, on Ultra Settings with everything turnt on except SSAO.

Edited December 16, 2021 by SCG_Fenris_Wolf

[Stolle]

I tried it with NIS and there was too much shimmering (even on the edges of the rectangular buttons in the menu screens). For me it looks better with the AMD setting + ingame sharpening at Ultra settings with 2x msaa. No hdr or ssao. I'm getting mostly 90fps and avg 80-85 per fpsVR on some of the scripted campaign missions.   

My rig: 11900K@5.1, 2x16GB 3600-CL16, RTX3080ti,G2.

I understand you mean everything on, except ssao and sharpen and antiliasing.

 

I gave it a try with the same configuration and it looks indeed quite nice, and it run smooth. Planes are less blurry but still very tough to ID and see emblems and color pattern except close distance.

 

Do you run in Nvidia settings all values by default?

[tinklepee]

I get shimmering on distant landscape/objects and it's made worse using upscaling but the performance is nice. I think the only thing that would remove shimmering is temporal anti aliasing.

What is your setup?

 

Yes of course, I run all Nvidia settings by default. For VR, please do not change the Nvidia settings - anymore.

 

Not even Energieverwaltungsmodus to performance mode anymore, keep it on normal to not have your GPU run into throttling earlier in situations when it really starts to sweat. With the RTX 3000 series especially. Nowadays they manage much better and it won't help you avoiding spikes in demand, much the opposite is tru nowadays due to the throttling.

 

There's some older, false information going around, people keep clamping LOD bias and other bs, it's like a revolving post. A recommends to B, B to C, C to D, and D posts it and A feels it's true. Many things change over time, and these are some.

 

The only thing that may remain true to adjust to smoothen performance are pre-rendered frames in VR at the bottom of the list in the Nvidia settings. It's effective in smoothening 0.1% and 1% low fps drops, if you experience them. If you do not have such, it's not necessary, it depends very much on your hardware, overclock, etc. Please be aware though that it introduces noticeably latency in rotating your head the higher you put it (the feeling if your view catching up, noticable when you shake your head the easiest), which is especially noticable when you use screen refreshrates below 90Hz, such as 75Hz on a Pimax or 60Hz on some others.

The shimmering in itself is native to IL-2's deferred shade rendering pipeline. These occurances are witnessed and need to get tricked around, but it's incredible hard to do so. The type of rendering bears other advantages, such as being able to manage many more light sources and more, however, its downsides are rarely worth it (in my opinion, others may disagree), most VR titles use forward. Forward would allow compatibility to eye-tracking devices, true DLSS, variable rate supersampling, VRS wrapper, and other modern technologies. 

You can check these out here if interested: https://developer.nvidia.com/vrworks/graphics/variablerateshading

https://developer.nvidia.com/vrworks

AMD has similar SDKs but much less presence in market with GPUs and some Säue would argue its doc and support is was not as good in the driver/SDK segment of things. QC in drivers also needs improvement, it's still somewhat of a WIP, but the good side is they went fully open source and that will eventually take off the longer it lasts. At least that's the hope. Check this out: https://gpuopen.com/

Here we go, this post may be lacking a bit of a red line, it grew organically like European roads, so to speak.

Do you need GeForce Experience to make this work or just Fholgers app?

Thanks

[dgiatr]

I tested today with 0.7 nis renderscale and 0.9 sharpen, not happy with it. It killed my fps, i had about 20 fps less with the same image quality. I use 0.8 renderscale in fsr and 0.9 sharpen with about 70 fps on quest 2 and 4xmsaa!!!in game graphics ultra settings, not ssao,hdr on,  low mirrors and shadows, in game sharpen=0, about 2700x2700 target resolution on steamvr (1.5× on OTT)...quite happy with it...i dont think i can get better than that...(nvidia rtx 3060 ti).

 

As a last try, you think i should go lower than 0.7 renderscale on nis to make it work( better fps) or should i finally stick with fsr?

First of all, no msaa, no postsharpen in-game. Then, it is certain there must've been some mistake during installation, setup or settings, be it Nvidia's not on default or anything else.

 

It gives better performance 100%.

V2.1.1 just out...   https://github.com/fholger/openvr_fsr/releases/tag/fsr_v2.1.1

[vonrickenbecker]

Just came across this topic and looks very interesting. I have an older (and somewhat under-powered for VR) machine, so any performance gains I can squeeze out are always welcome!

 

I had a couple questions just to clarify:

1. All in-game Anti-Aliasing (MSAA, etc.) should be turned off when using this mod? @SCG_Fenris_Wolf's comments seem to indicate that, but I really dislike how the game looks with no MSAA. 

2. Same for in-game sharpening post-process filter?

2. Same for in-game sharpening post-process filter?

 

Hello , i am using Quest 2 with FSR (renderscale 0.8 and sharpness 1.0)  at 2700x2700 final steamVR resolution (OTT set to 1.5x) at about 60-70 fps.

 

I don't know how IL2 looks through other headsets but for me the game looks terrible with no ingame MSAA so i set it to 4xMSAA. I tried once to turn off ingame MSAA and go for a higher resolution ( about 3200x3200?....i don't remember exactly) instead but i wasn't happy with the final result ( little image distortion and more shimmering than now)

 

Its true thought that i don't use ingame post sharpness (set to o) and use only FSR sharpness set to 1.0 as i said before.
