Hi,
I am trying to a way we can have a
desktop performance compared to windows/macos on linux where system is
optimus-enhanced (nvidia) focused.
I have read about off-screen mesa. So ubuntu has gl_dispatcher strategy, why not make osmesa defaults and let gl_dispatcher take care of relative device (nvidia, amd, nvidia) when optimus-enhanced is in set.
On-demand nvidia-prime profile runs Xorg nvidia's vram, ok?
an alternative config says intel/nvidia as default opengl ...
Maybe
osmesa (off-screen mesa) default background, when optimus-enhanced is
needed/set, should communicate gl_dispatcher and decision what device
take control could be set. I think it is a good strategy together with
envvars.
We could have hybrid-profile (nvidia-prime on-demand) in addition to powersave (intel/amd) amd performance (nvidia-only)
For testing i have set:
LIBGL_ALWAYS_SOFTWARE=1
GALLIUM_DRIVER=softpipe/llvmpipe
GALLIUM_DRIVER=softpipe/llvmpipe
And desktop lag was terrible
Thx
Luiz
