+1. I'm surprised it's not supported. I'm playing Quake 2 RTX in 60 fps 4K on my 7900 XTX, so it will easily handle this.

I'm surprised too, especially since it has a RTX Remix renderer which is compatible with AMD

PRB Doom is working flawlessly with AMD: https://youtu.be/i2Ld9YNUWls

It's definitely possible.

It's just that.. I'm quite drained with mental resources, it's s hard work. Plus, I would want to debug it locally (to see the corner cases, to polish the frame pacing, stuttering etc), I don't have AMD.

I wonder if someone from AMD could help out here, I think this would be pretty good for PR.

I tried all different kind of drivers already on my 7900XT without any luck

Actually there are two versions... The RTX one and the normal one. The RTX one is normaly never working (at least not good) with AMD cards.

I did the Portal RTX AMD and Steam Deck mod, so I doubt this would be any trouble if it actually loaded

Quake 2 RTX works perfectly with AMD cards.

I think Quake2 is not done with Remix isnt it ?

It is not, Quake 2 RTX came way earlier

It seems to be the the fluid simulation that's causing it to crash on AMD cards. If you go to "/Documents/My Games/GZDoom/", edit the gzdoom-rt2.ini file, and change the line "rt_fluid=true" to "rt_fluid=false", that should let you play it, just without the blood splatter. It runs really well on my 6800XT after making that change.

It works!

I actually wasn't a fan of the blood splatter so I'll try this out right now

alright so for me, I just keep getting driver timeouts now :/

You might also try changing "rt_dxgi=true" to "rt_dxgi=false". It seems like the Vulcan renderer might be more stable on AMD cards for some people. If that doesn't work, I'm out of ideas, sorry.

It was already off but I found the solution. My display was set to 4k but setting it to 1080p fixed everything

DarkVamp commented 3 months ago

Runs VERY WELL on my 7900XT in 3440 x 1440 Ultrawide and FSR QUALITY. The raytracing is a little noisy but besides this its awesome! The VOXELS are just changing anything.

On my 7600 I'm doing 1080p with FSR balanced, FSR really holds up in this game

I have an AMD Radeon RX 6800 XT and GZDoom RT would crash upon start with (Access Violation - tried to read address 0000000000000008).

I didn't have the gzdoom-rt2.ini but I downloaded it from here and put it in the gzdoom-rt-1.0.2 https://gist.githubusercontent.com/callofcthuloo/2a4e373be727cb78a391aba64e7f0e87/raw/5992504988df4c8b315dfc9ef6ab3781be4dd703/gzdoom-rt2.ini

And then set rt_fluid=false

Now it works! I didn't find a clear explanation on how to get it running on AMD GPUs, but this seems to be it!

I assume that rt_fluid stands for a cvar for nvidia's [fluid simulation API] which utilizes CUDA, which AMD cards don't have. AMD cards obviously can do any sort of particle simulation without any APIs required, and can do it quite well. https://youtu.be/clAqgNtySow
