Tried box64 on a Raspberry Pi 5 the other day and it worked above expectations. Except for a minor glitch with OGG audio, I got about 60 FPS in Xonotic (x86_64 emulated on AArch64).
For games in particular, the best performance comes if you use a dedicated GPU [1]. Though the CPU emulation can still be a limiting factor.
I'm able to play most 5-10 year old games that aren't tied to DRMs at 30-60 fps on a Pi [2] (and certainly on Ampere) using box64 and an AMD GPU (or Nvidia on an Ampere system), haven't spent much time with FEX-emu though.
I spent some time testing Steam with FEX on the Orion O6 using an AMD RX570. Really surprised it worked as well as it did.
Portal 2 was hitting over 100 FPS. Half-Life 2 and DOOM 2016 hovered around 60 FPS. Shadow of the Tomb Raider and Control mostly stayed above 30 FPS, while The Witcher 3 and God of War usually hung out in the low to mid 40s.
Orion O6 has so much potential, just wish Radxa had a little more focus on just getting one product launched really nicely, instead of spraying out more hardware every couple months.
Indeed, the rollout of the O6 has been disappointing. At least we have two additional companies releasing SBCs with the CD8180, so development won’t be limited to one board.
God of war runs great on my snapdragon 8 v2 or whatever x13s laptop...but gots so hot the GPU clitches since I don't think that laptop has active cooling
