The request from developer Natalie Vock noted:
Various people have been playing Indiana Jones: The Great Circle with RADV_PERFTEST=emulate_rt on GFX9/GFX10. RT support is required to launch the game, and performance is okay even with emulation, so enable it by default to make the game playable for everyone running older (GFX8-10*) GPUs.
*This includes GPUs released all the way back in 2014 covering the Volcanic Islands, Polaris and Vega series. So that’s the likes of the Radeon R9 285, Radeon RX 480 and Radeon 520/530 + Radeon RX 530/550/570/580.
As of 15 hours ago, the change has been merged into RADV and so it should be available in the upcoming Mesa 25.1 release. This means the game will be playable on some pretty old GPUs, although performance may not be amazing, at least it will work now.
Mesa 25.1 is due for release potentially sometime around May 7th. That’s when the final release candidate is scheduled, which may turn into the final release.
