Hi Jan,
could be a mainboard issue can you try to put the fx 3400 in the
computer with the fx 1300 card.

Hi there,
sorry for not following this for quite a while, some project
deliverables were waiting (not too patiently) .. ;)
I've in the meantime built a less sensitive test case for the problem
mentioned then (performance problems with recent builds, FSAA and
geforce quadro fx 3000 / 3400) and dug a bit further into the problem.
I've ruled out transparency sorting which I suspected at times, both
seem to not very much affect the problem. My test model is originally a
VRML file, built through the 3DS Max exporter.
Although less complex (<700k Triangles) than the original data, my
current test case still shows the same problem(s). On my FX 1300 (3 Ghz
P4, 1 GB system memory, PCI express) it achieves:
65 fps with environment maps and __GL_FSAA_MODE=0
max fps w/o environment maps and __GL_FSAA_MODE=0
9 fps with environment maps and __GL_FSAA_MODE=7
max fps w/o environment maps and __GL_FSAA_MODE=7
The other system, a dual P4 3 Ghz, 4 GB memory, FX 3400 PCI express:
max fps with environment maps and __GL_FSAA_MODE=0
max fps w/o environment maps and __GL_FSAA_MODE=0
2.7 fps with environment maps and __GL_FSAA_MODE=7 ???
max fps w/o environment maps and __GL_FSAA_MODE=7
(all done with '10loading', fixed window size 1024x768,
setSortTrans(false), setWriteZTrans(false), same most recent nv driver
revision, Textures are all 512x512 (12 Textures), anisotropic filtering
is off)
For me this still looks a like the card for some reason needs to use
system memory at times - only the why is wierd, since for one I can't
really see why the 3400 is actually slower than the comparatively weak
1300 - and additionally, I don't see how I can fill all this memory with
this amount of data, even for __GL_FSAA_MODE=7.
12 * 1 MB + framebuffer (with 4x Multisampling - mhm, about 64 MB?) =
76 MB, the geometry shouldn't take THAT much more ... so I don't really
see the reason for the card to drop into using system memory transfers.
Plus (although I unfortunately can't name the exact dailybuild) it used
to work at one time.
Anybody any ideas? ;) I can make the geometry / maps I used available
for testing this time, however the thing's a bit largish - especially as
a .bin with the envmaps.
Best regards,
-.jan.-
