@ari@fedi.arimelody.space Is our RootFS actually bundling rpi GL drivers at all? If not, is it perhaps using zink?
Two things two check. I don't know the filename of the rpi GL driver, and it'd be interesting to see if forcing use of zink on the host side helps :)
(Also mangohud could be used to tell for sure which driver it's using without library forwarding!)

@neobrain@mastodon.social fascinating! with libraries forwarded, mangohud reports identical drivers on host and guest (V3D 4.2.14.0), but disabling forwarding instead reports zink from the guest. that seems to prove your lack of rpi drivers on rootFS theory. testing it further: glxgears native at the same resolution gets about 100fps with openGL, and 250fps with zink. really impressive!! unfortunately, i don't appear to get the same performance gains when deliberately using forwarded zink in half-life.
