Dolphin, the GameCube and Wii emulator - Forums

Pi is now Vulkan 1.1 conformant and the changes will be available shortly they are claiming performance increases too https://www.raspberrypi.com/news/vulkan-update-version-1-1-conformance-for-raspberry-pi-4/?fbclid=IwAR2R68Q5-dzNR6cCzbYIS8RS1x13Lpoe65ZaOP3tlATBgkmf_WK5ekJnqMs


Performance increase in percent

I'm going to attempt to find some time to build dolphin on a fresh pi install and see how it goes.

A comparison between Vulkan and OpenGL ES with probably an older Mesa version (with emulated underclock): https://www.youtube.com/watch?v=cUUeE35fNTs
Pretty interesting to see OpenGL ES performing better while in other instances Vulkan is quite a bit better: https://www.youtube.com/watch?v=TLzFPIoHhS8

Maybe a specific extension is used which is slow on RP4 or Dolphin's Vulkan implementation is slower?

These changes were just pushed unless these individuals built from source (I only skimmed the videos so sorry if I missed that). So hopefully there's a change between them and the newest update.

I'm getting about 3 more fps than before but it's margin of error numbers.... I can't figure out why Dolphin is reporting the Vulkan Version as 4.2 instead of 1.1 unless I did something wrong when I built Mesa.
