prboom-plus-rt VS Q2RTX

The latest release of this Classic DOOM Mod added support for AMD GPU's: https://github.com/sultim-t/prboom-plus-rt/releases

Doom Raytraced -> https://github.com/sultim-t/prboom-plus-rt/releases/tag/v2.6.1-rt1.0.6 (based or prboom)

All Doom engine based games. There's already Doom with RT, and I've heard that someone already created lighting data for Doom 2, but there's also Heretic, Hexen and Strife. Especially Hexen! It looked pretty awesome as it was those days at 320x200, it obviously looks light years better running on modern engines, but I imagine it being absolutely mind-blowing with RT.

Doom. With RT it might even actually run at 100 FPS now... Last time I tried, I had to use FSR to hit 100 FPS at 1440p, and that was with a 3080 Ti.

I have a question about using PrBoom+ - before anyone asks why I'm using that instead of GZDoom - it's because I've been playing a lot of the ray-traced Doom mod which I think is amazing - and that mod has been done for PrBoom+ : https://github.com/sultim-t/prboom-plus-rt/releases

I think he means PrBoom-Plus-RT that was linked by /u/Wietse10.

By doom-rt I'm referring to the pathtraced (that is, full ray tracing, no rasterization) of Doom from 1993: https://github.com/sultim-t/prboom-plus-rt/releases

I hope you're at least playing [Doom RT}(https://github.com/sultim-t/prboom-plus-rt/releases) on that now! The SM64 PC port has a Raytracing mod now too, if you're up for figuring out how to compile and install that.

I mean, there’s a version of PrBoom+ that has ray tracing. here

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.
