FidelityFX-FSR2 VS Q2RTX

- https://github.com/GPUOpen-Effects/FidelityFX-FSR2/releases/download/v2.2.1/FidelityFX-FSR2-v2.2.1-prebuilt-sample.zip

AMD's scaler is open-source. Here's the github for FSR2.

Sure, go ahead: here is the link. Go contribute and make it better, as it's an OPEN SOURCE project.

DLSS is a proprietary black box that developers have no control over (bad). FSR is open source, you can check the code, fix the code, modify the code, and port it to new devices (good). It also means there is a community of developers who are trying new things and submitting code for inclusion (there are currently 148 forks on the github).

literally not true. FSR has been constantly updated in the background and 2.2.1 was released 3 weeks ago.

If I get the FSR API files (ffx_fsr2_api_dx12_x64.lib, ffx_fsr2_api_vk_x64.lib and ffx_fsr2_api_x64.lib) from github what directory structure do they need to go into? Looking at working DLSS and XeSS as a template...

From the official docs:

But like another commenter said, Q2RTX is free for the shareware version so just give it try! https://github.com/NVIDIA/Q2RTX/releases

First, are you sure you're using the latest version of Q2RTX? Get it from here just to be sure: https://github.com/NVIDIA/Q2RTX/releases/tag/v1.7.0

https://github.com/NVIDIA/Q2RTX A really solid a-svgf implementation by nvidia in quake. A-svgf is a basic denoiser.

We can be pretty much sure that the parts of the Q2 RTX code that uses the Vulkan RT API are optimized for Nvidia, as Nvidia basically developed that API. Until the official Khronos Vulkan RT API was finalized, Q2 RTX used an Nvidia specific extension which was committed by an Nvidia engineer.

I'm not confusing anything, I've been following this stuff very closely, Q2VKPT was a solo project by Christoph Schied and was actually primarily meant to showcase/test his denoiser, Nvidia saw his project, thought it was cool and probably that it would be a good test bench for VulkanRT and so they've decided to expand on his project to see how far they could take it. Quake II RTX is absolutely open source, since the original code is licensed under GPL v.2 it can't be proprietary nor contain proprietary code in any way, that's why DLSS and Flow were never implemented, because if they were they would have to be open sourced as well (though Flow has been recently open sourced anyway), here is the code: https://github.com/NVIDIA/Q2RTX

Modded yes it has a lot of upgrades, but the official Quake 2 RTX hasn't had an update in almost 1 year (since Jan 2022): https://github.com/NVIDIA/Q2RTX/releases

Minecraft RTX = 8 temporally afaik Quake 2 RTX = 1 or 2 (tweakable) Lego Builder's Journey = 2

I'm assuming you already implemented it like this? https://github.com/NVIDIA/Q2RTX/blob/master/src/refresh/vkpt/shader/asvgf_gradient_reproject.comp

There is a mod for Serious Sam, one for Doom (the original) and Quake II RTX (the most impressive since it's done and maintained by Nvidia programmers) if you're into retro stuff, I don't personally know of any free modern games though.
