Emulate Hardware Ray Tracing Support on Old GPUs (GCN Old)

Описание: RADV ray tracing lets you emulate ray tracing in software in order to let you play games that require hardware accelerated ray tracing like Indiana Jones and The Great Circle. Even GPUs that don't support ray tracing like the RX Vega 64 get excellent performance and that isn't even an RDNA GPU, it's Vega! Really amazing work done by the developer(s) who implemented this into RADV/Mesa for the AMDGPU driver on Linux. You guys (which includes gals) are doing the peoples work and doing your part to reduce e-waste!

And thank you to the people who uploaded videos to YouTube testing it, I wouldn't have been able to make this video without them, so go like their videos!

I made this video because ‪@fpgamemearray‬ commented on one of my videos enlightening me to the fact that this was possible. Thank you for sending me the links to this and making this video possible!

Excellent videos posted by other youtubers whose videos showed me this was possible and that I used for this video:

I did not run these games myself and it's thanks to these videos that I was able to analyze how it runs and provide commentary on the news articles by Phoronix linked below.
