Support for Intel ARC A770 in this game and Quake? It's a pretty capable GPU but both games won't run :/, alas.

prboom+ isn't a source port made to run quake. You should look into Nvidia https://github.com/NVIDIA/Q2RTX repo instead.

The RT not working on A770 is still relevant to this project, even if the Quake mention is not.
