Retropie on Pinephone

[Luke]

I've been testing out the playstation emulator and notice that disabling vsync doesn't help as much to improve fps for 3d games as compared to 2d games.

For a like-for-like comparison, I ran streetfighter alpha 3 on both mame and pcsx cores on retroarch. I guess there's more overhead on the pcsx emulator but slower paced games are playable.

sfa3 in mame 
--vsync--on ~35 fps
--vsync-off  ~70 fps

sfa3 n pcsx
--vsync-on ~25 fps
--vsync-off ~35 fps

Have you tried to pair a BT controller with the phone?
