Quake 1 - DirectX Raytracing

[icecoldduke]

I started work on a DirectX Raytracing port of Quake 1. The entire game is raytraced, and requires a Nvidia 20xx or a Nvidia 30xx. This video was shot on a Nvidia 3080. The engine supports real time raytraced lighting and shadows(no bump mapping, I wanted to keep the composition of the original game, but with raytracing), raytraced Ambient Occlusion, and real time raytraced reflections.

All the levels are playable. You need a RTX 30xx or 20xx card, but a 3080, 3090 and 2080 are recommended.

Looks good! I'm currently without a dedicated graphics card at the moment, but when I can get my hands on an RTX 30 series card it's the sort of thing I'd really like to check out

I'm a fan of the first Quake and it looks promising. I'm not sure whether the reflections are where they should be, but I suppose this will change in the future. It's only a preview after all. Imagine a combination of ray tracing and Quake HD Pack for example...

Im more suprised you got a 3080 that wasnt malfunctioning lol

I ran some performance metrics. I recorded a demo, played it back on a 3080, 2080 and 2060 to show performance.
