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.
