, glxinfo tell me that i have direct rendering (without this
performance<BR>was worse and 3dmark wasnt end without errors)<BR>i was put
glxgears score to show that opengl working and for compare with<BR>boards who
have other memory speed (i have 512Mb ddr 333) <BR><BR>i suspect now that
performance is low cause in windows was implemented in<BR>drivers code to
emulate T&L and vertex shader , and maybe wine and programs<BR>in opengl
have to emulate this ...<BR><BR>could be implement in intel drivers code which
would be emulate opengl <BR>functions of T&L and vertex

<DIV><BR>915 and above chipset have pixel shader (2.0 following directx spec)
but no<BR>vertex shader and no T&L stage. Under linux with mesa when the
card haven't<BR>a feature it's emulated by software (mesa stuff).<BR><BR>I don't
know much about the intel 3d driver (i830, i915, ...) but i would have<BR>think
that it was on pair or even better than the windows one, seems i
am<BR>wrong.<BR><BR>Anyway there is still a lot of developement and improvement
in the linux intel 3d<BR>driver mostly thanx to intel because they pay people
for this. You could also<BR>try man intel or man i915 (ddx driver name) and see
what option you got,<BR>tweaking some option might give you a performance boost.
There is also<BR>drioption try driconf tools to see what you can tweak for
intel.<BR><BR>best,<BR>Jerome Glisse<BR></DIV>

<DIV><FONT face=Arial size=2>=> so ... i have to wait for improvments
of mesa emulating , or wait for intel merge in drivers the same emulation like
in windows ...</FONT></DIV>
