Harry i am sorry but i can't agree with your recommendation:
we tried a lot of cards with different X-servers and at the end we came back to
nvidia's TNT2
which seems to us the most stable graphic chip for performer.
We tried out:
TNT2 with old nvidia driver: works fine and fast, no breakdowns
( except of changing the resolution during running Performer applications
crashs the system)
TNT2 with current nvidia driver: Applications with no textures are running for
a while,
Applications with textures crashes the Xserver and blocks the console, only
remote reboot possible
GeForce and GeForce Quadro with old nvidia driver, doesn't crash but you can
see only an empty window
(concerning Performer or OpenGL applications)
GeForce and GeForce Quadro with current nvidia driver, same as TNT2 with
current nvidia driver
If somebody has other experiences or success using the GeForce please let
me know
Permedia2 with Technology demo X-server (EV2): runs fine but slow, only
software texturing
Elsa GloriaXL with Xig's Professional Edition Server: restart of the Xserver
Voodoo 3 2000 with Xfree 3.9.18: runs almost fine, but sometimes pauses for 1-2
seconds
has trouble with alpha blending textures ( looks like )
We didn't try Metro`s X-server, may be somebody out there has experiences with
it.
To me it seems that a lot of people are experimenting with different cards and
different X-servers and
sometimes this is really a nerve exploding job ( I see some of you agree ... )
and the result is
frustrating. It should be mentioned that this is not the fault of SGI, it is
the problem of the extremely
heterogeneous mixture of different PC components you can choose to build up a
system and
unfortunately the chip manufacturer were a bit on the slow end of providing
informations for
GL hardware support.
I think it makes sense to collect those informations concerning graphic cards
and X-server
( Hello Allan, Hello Angus ;-) ), so that not everybody has to pass sleepless
nights because he
cant see the Tux flying through the Performer town.
If nobody wants to take care about that, i could try to collect all
informations and write it down.
So please if somebody has experiences or informations let me know and i will
extract and distribute
it. It also would help to reduce the Linux performer graphics driver noise in
this mailing list, lets
go back to performer work.
