Q2RTX VS DLSS

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.

Also DLSS has pretty strict requirements in advertising, requiring nvidia logo & adverts on splash screens and give nvidia any rights to use your app in their own advertising. [0] It's certainly not "free". A completely night and day difference to FSR, which just uses MIT [1]

Lots of people online seem to believe both are "free", so the only reason why you wouldn't implement one is some back room deal. But in my experience, just getting everyone into the same room to sign off on things like that is hard.

"IT doesn't work that way. DLSS may be a click in some Unreal Games, but custom engines? Yeah, no. You need to modify the code to implement it, which is PROHIBITED by the license Nvidia has you accept when you accept their SDK terms: https://github.com/NVIDIA/DLSS/blob/main/LICENSE.txt DLSS is not FOSS (Free and Open Source) like FSR. For comparison, FSR's license that lets you do whatever the hell you need to get it functioning in the game or improve performance: https://github.com/GPUOpen-Effects/FidelityFX-FSR/blob/master/license.txt Blame Nvidia for devs not wanting to touch non-free code and enter a legal agreement where they may be litigated down the line...for implementing a technology that SELLS Nvidia GPUs. It's literally like me threatening to sue you for bringing customers to my business. Again, blame Nvidia. By the way, they are also the one that sold you the feature, so let them be the one to implement it. I keep hearing Nvidia is a "god tier software company" but can't implement DLSS on the driver side? Somehow I don't buy it, especially when they release game-ready drivers anyway. And before someone brings up the BS argument it needs game data, anyone can find those memory addresses to get to the engine or they can ask. Considering they are Nvidia, don't think any game dev will keep silent about it or how to interface with their game if there are driver issues. EDIT: Also just so you know, XeSS is also under a similarly stupid license as DLSS XeSS License: https://github.com/intel/xess/blob/main/licenses/LICENSE.pdf Keep in mind this nugget from Intel's license: "No reverse engineering, decompilation, or disassembly..." Only issue is that games need to be DECOMPILED when DEBUGGED! "

Literally. https://github.com/NVIDIA/DLSS
