PS5 Linux (4.03) | RPCS3 | MotorStorm: 3D Rift
4K for bitrate purposes. I haven't been able to make 4K work on my setup, ps5-linux EDID support is a bit wonky right now.
Internal resolution upscaled to 1080p on RPCS3.
Stock clocks.
External SSD Linux installation. I yet have to find a decent/cheap M2 nowadays. It would be convenient for PC games, I don't think it would make any difference for emulation, most/all the game is probably dumped as is into the memory.
Flat performance line all across, not even dips while caching shaders.
PS5 is a serious low-mid ranger Steam machine right now and probably the cheapest emulation powerhouse of all time. One could argue XBOX Series X is also a good emulation machine, but it has absolutely nothing to do with the Linux emulation support.
