Request: Port to Reshade.fx format

[abwezi]

I see there is an .hlsl port and from my brief research that is supposed to get it nearly to being compatible with Reshade but I tried renaming to a .fx file and adding to reshade and it still gets errors compiling. I'm not knowledgeable enough to make whatever changes are still needed to make it compatible as a reshade.fx shader, but I think that would be a great place to have this available. Then this shader could be iniected into something like Shaderglass or Lossless Scaling and be used with basically any windowed/borderless app

The Reshade team is working on it.

Someone successfully ported it but the behavior isn't good yet:
This is a refresh cycle shader, not a frame shader.

It has some technicalities that makes it a bit difficult now, if you are a software developer, maybe help them?

Update: The ball is in Microsoft's court, possibly with the assistance of GPU driver vendors to provide reliable realtime support for this.

We need this feature to come back to Windows properly (it's not in the latest Direct3D AFAIK)

Please see Blur Busters Open Source Display Initiative for why we need refresh cycle shaders for purposes other than CRT or BFI. Including many mainstream use cases and ergonomics.

So I'm gathering until Windows, or rather Direct3D gets this feature back properly a proper ReShade port isn't in the cards?

Would it not be prudent to just use an older version of Direct3D? And is there a thread on the reshade forum discussing this?

[mdrejhon]

Check the ReShade DIscord channel. They are working on some kind of a compromise.

I suspect it's still a frame shader, but one that spawns multiple frames continually like their BFI, and possibly working best with full frame rates. I'm not 100% sure what kind of algorithm they plan to do without a refresh cycle hook, but I'm hoping they pull it off!

Update: After asking multiple members of the Reshade team, they all stated it was impossible and not coming to Reshade. Here's hoping someone figures out an alternative.

It's not ReShade's fault, it's Microsoft's fault. They need to reintroduce a proper version of Composition Swapchain, because that will really help ReShade.

The reshade addon WibbleWobbleCore has an implementation of the beam simulator https://github.com/PHARTGAMES/WibbleWobbleCore
It works mostly well, but there is a seam I am getting in the middle of the screen along the scan axis that seems incorrect, I reported it to the author and he is trying to figure it out

Try troubleshooting through the HOWTO in #4

CRT.fx.txt

I tried something but still flickering and stuff. Idk if someone can improve it so imma just post it here.

This should work OK if you're able to run the software at guaranteed perfect framerate=Hz (I think Hz as CRT Hz, not native Hz).

The problem is when frame rates varies. The CRT simulator requires perfect framerate=Hz independently of underlying frame rate.

I tried this with gamescope and it seems to work well, better than before!

edit: looks like its mainly the temporal frame swapping thats helping the flickering a lot, a value around .7 works well on the Ally with a 120hz screen.

edit: do you have suggestions for making the fx even better. I think you are thr only guy here who can do it.

It seems the above reshade fx file made by itsowen, while flickering intensely using regular reshade, works better while using Valve's gamescope implementation of reshade which seems to run a bit more stable. Note this is obviously only on Linux. Youll have to turn temporal blending up and adjust a few more settings depending on your display.

I would think a solution would be to port the shader code into C++ as i believe thats what gamescope is using for its internal filters such as NIS,FSR, etc. With this code it could be added to gamescope's internal filter system which I believe is what valve is waiting on people to do already to submit to gamescope. I don't have any experience with this kind of development but I'm excited to see if someone could get this natively working on handheld PC operating systems such as steamos and bazzite.
