Quake II RTX - Ray Tracing in games
« on: June 07, 2019, 06:49:46 PM »
nVidia has a version of Quake 2 that supports RTX ray-tracing out;

Direct download here:

Or you can also get it free on Steam. It looks like it's just the demo by default, but if you own Quake 2 on Steam you can upgrade the whole game to RTX as well.

Originally they had said that only the 2000+ series of nVidia cards would support ray-tracing, but they recently expanded that to the 1000 series too (making it clear it wasn't really a hardware thing but a restriction they put in the driver).

I've got a GTX 1080 (non-Ti version) so I tried it out.

It defaults to your desktop resolution; that's a problem because at 4K on my PC (3rd gen Core i7, 32GB RAM, 1080 GPU) it ran at about 0.5 FPS. There's an FPS counter but it doesn't seem to read lower than 10FPS, and this was clearly lower than 10.

Bumped the resolution down to 1920x1080 (1080p) and... I get 11fps.

All the way down to 640x480 and it finally runs at 60fps. Tried 1024x768 and it drops all the way to 28fps (between 25-30, depending on the area).

Visually it's cool, you can switch back to the original OpenGL rendering mode and see the differences; with the low-poly models in a game this old it's not the best way to show it off, but it's at least clear what the ray tracing is doing and the lighting and explosion FX all look good.

It doesn't seem like even a 2080Ti card could run this at 1080p/60fps though - probably 30fps tops, and 4K isn't even remotely viable - and again, this is in Quake 2 - so RTX + a modern game doesn't really seem viable for at least a couple more generations, though this demo may not be the best optimized.
