AMD FSR can be added to sodium?

[baturalp1337]

Hello, maybe you know. AMD introduced FSR technology. Same functionality as DLSS. It would be great if the FSR comes with sodium. It gives a huge FPS boost (if the graphics card supports it). I think it would make a lot of sense if it was added to Sodium.

From my knowledge, a technology like this would be near impossible to port back to Java, and likely has no support from AMD. Even then it would have limited use in a game like Minecraft due to its main problems with performance being due to how it is written and what it is written in.

In a theoretical world where support already existed for Java, this would primarily have more use for scaling to higher resolutions.

Supports:

• DirectX®12.
• DirectX®11.
• Vulkan®.

This will not be worked on. In addition to a lack of Java/OpenGL support, the amount of work to support this would be at least the same amount as rewriting the entire Minecraft client, for a fairly small percentage of users

thanks for info :)

It's just a post-processing shader, it has been ported to OpenGL (https://jntesteves.github.io/shadesofnoice/graphics/shaders/upscaling/2021/09/11/amd-fsr-demystified.html)

Seems like this sort of moved to #1075

Thank you for the link. I apologize for closing this so abruptly. It was not immediately clear to me what FSR was at the time of the initial post. I (incorrectly) assumed it was a closed-source executable meant to run alongside a game based on AMD's marketing jargon. I was not aware that FSR was a shader or that it was open source, until you posted just now.

Of course, questions still remain if integration is to be considered:

• Will this shader work with Sodium?
• Does it demonstratively improve performance in Minecraft?
• Will adding this shader harm Sodium's compatibility with shader mods (such as Iris)?
• Does Jelly think this is a good fit for Sodium?

I agree it looks like discussion has moved to the other issue, I would encourage you to post this link there.

Found this recently that ports fsr2 to OpenGL. Of course the biggest issue it would be that it's written in c++ but maybe writing some JNI bindings will work?

Minecraft does not have motion vectors and generating them is non-trivial (see: very hard) due to the game's rendering architecture. There's going to be practically speaking very little performance benefit to implementing any kind of advanced upscaling technology, given the game's pixel shaders are so incredibly simple.

Hmm right. Afaik shaders like PTGI 3 need motion vectors which is implemented in iris. I suppose adding FSR would be something to discuss there rather than in sodium 🤔

[TheNukeLore]

iris does not add motion vectors, ptgi 3 just lacks motion vectors when used on iris.

Sorry that this isn't specifically related to Sodium (love the work you've done btw). Lossless scaling is your friend. Works great and supports FSR and frame generation. Leave Minecraft in windowed mode and let lossless scaling resize the window and do its magic. $6.99

Oh it works now? Last time I tested it failed to work with Minecraft

It's been working well for me. I've tested it on a micro PC with an n4000 cpu all the way to my main PC with an RTX 4070. I usually set the upscale ratio myself and let the app auto-resize the window. Capping the framerate in the Minecraft video settings is useful if you use the frame generation. You can, however, tell that the upscaling is done without vectors. The image quality looks great, but reminds me of using a streaming service like GeForce now, or Stadia (RIP).

hello I found this allows to integrate amd fsr 1.1 with GLSL files (file extension for opengl sahder): https://gpuopen.com/manuals/fidelityfx_sdk/fidelityfx_sdk-page_techniques_super-resolution-spatial/
