how did you get hardware acceleration without DRI?

why ? how huge ?
I understand that direct rendering could improve performances but
I can run very GPU expensive patchs you made without direct rendering
and without noticable difference.
So it may be worth a try...

hello,
since texture sharing seems to work between context inside one Gem's
instance, I'm now wondering how we can introduce texture sharing
between process.
According to [1], texture (and more generally display list) can be
shared between process if direct rendering is disabled and process are
using the same X server.
If I understand correctly, the only thing to do is to share the
display list structure over process.
Could we use shared memory to do that ?
I look into the [gemglxwindow] and [gemglutwindow] code and it looks a
bit obscure to me, it uses advanced C++ idioms (PIMPL for the former
and CALLBACK4WIN for the latter) that I don't understand well yet. So
I want to know if this texture sharing between process is feasible
before going deeper.
direct rendering disable?
that's look like a huge problem...
