icecoldduke Posted October 24, 2020 I began porting Prey(2006) to DirectX Raytracing. Prey wasn't open sourced, but the game sdk was, so to start off I modified the idTech 4 GPL engine to load the Prey game dll. Then I ported all of that to 64bit. Then I removed all of the Doom 3 backend rendering code, and brought over my DirectX Raytracing work I've been doing on Quake 1 through Quake 3, and modified it to work with the idTech 4 data. Here's the first bit of results doing that work. 2 Share this post Link to post
