Descent • Parallax Software 1995 (DXX-Raytraced Source Port / First 5 Levels)
Descent was develeped by Parallax Software and published by Interplay in 1995 for PC DOS and Mac and in 1996 for Playstation. In the craze of DOOM clones it innovated with 6 degree of freedom control and fully 3d environment and enemies (before Quake), sprites were still used for pick ups and some of the effects. It supported high res SVGA graphics modes, but at the time there was no PC that could handle that at fluid framerates.
Here I'm using a port that adds raytracing to the old game. Get it from the link below, it comes with sharware version of descent.hog and descent.pig files, but if you own the full release you can swap those files from the full version.
DXX-Raytraced Source Port:
https://github.com/BredaUniversityGames/DXX-Raytracer
This port adds physically-based renderindg, pathtraced global illumination, soft shadows and other modern rendering stuff. It adds a subtle headlight, probably to light some places that would end up totally dark due to way RTX works, you can change the instensity of it if you like in the options. You would think that it defeats the purpouse of the flares, but it dissipates rather quickly so it has pretty small "range" so flares are still pretty useful not only for opening doors ;)
I'm uploading playthorugh of the first 5 levels, but let me know in the comments if you would like to see more.
This port probably requires RTX capable GPU though I didn't find any info on that on its github page. The only bugs I've seen so far is a bit broken rear view and the map will render sometimes some junk lines that are not part of level geometry.
