Re: Quick graphics card question

[Todd Alan Peleg <todd(at)theholdingcell.com>]

Hey Morten

i don't know if i have an answer per se.. but i'll tell you the latest in my story so far..

so.. all the trouble i had with the quadro fx 3000 series being slower than my laptop geforce (256mb vs 32mb) .. things changed yesterday.
the systems guy here went onto the machines one by one and did the following:

registry cleaner
windows updates
latest nvidia drivers
turned OFF vertical sync on the card

the performance (on my test scene of a sphere moving from left to right over 100 frames.. in wireframe.. with all 4 views active) went from 15fps to around 95fps

no exaggeration... it was crazy..

so.. we don't know exactly what did it... but i can say the vertical sync trick that was posted here improved the playback speed about 10-20 fps

so..

its possible thta the results you are seeing aren't true test results.. but the result of other issues..

i am not sure how all that info ties into the wireframe playback speed.. but i saw it.. he saw it.. and everyone here (that cared) saw it..

hope that info helps

I have recently tested Geforce 8800GTX, Quadro 4600 and latest a GeForce 7950GT on the same dual quadcore machine with interesting but weird results.

 

All had the latest appropriate drivers and the Quadro set to Soft XSI and I used a test scene which I posted earlier. The 7950 was faster than the Quadro 4600, which I plainly dont understand, and the 8800 is very slow - even slower than my older 7800GTX on my old workstation.

 

I am about to purchase this new workstation and would like to put the fastest card in it for the money and was about to go for the Quadro because it is fast - about 2-3 times faster than the 8800, but then my latest test with the 7950 muddled the waters. It is 1/6th of the price of the Quadro and faster. I am thinking they might not have optimized the drivers for these newer cards for OGL yet, but they are not that new.

 

Question is if anyone here can offer any insigth that might explain this difference?
