More hardware, more tests.

The GTX 580 Classified is apparently overclocked at the factory. The GPU and Shader clock are both significantly faster.

GTX 580 -------------------- 512 cores - 290.36 Drivers - 3min 6.0 sec
GTX 580 Classified ---------- 512 cores - 290.36 Drivers - 2 min 50.4 sec
GTX 580 + GTX 580 Classified 1024 cores - 290.36 Drivers - 1min 29.7 sec

Sorry to be a pain in the butt, how do I add on the time it's taken and do I just leave it running or does it stop/finish/stamp itself to an image?
This is using the standalone RT that came with the Maya version.

[vlado]

Add the following options on the command line:

-rtengine=3 -rtsamplelevel=500

This will cause the rendering to stop after 512 iterations - you can then check the render time in the output from the standalone.

Best regards,
Vlado

Does anyone know if the amount of memory on a card effects the render speed much? 1.5GB vs 3Gb on a GTX 580 for example?

Looking at buying:

Ahh fantastic, many thanks Vlado !
I left it for about 40 mins and guessed I needed to add something else to it

... one of the reasons a 680 GTX is not making any sense.


680-GTX_800x450 2min23sec NV301.10



580-GTX_800x450 2min12sec NV301.10



580+680-GTX_800x450 1min11sec NV301.10


580+680-GTX_1080p 6min45sec NV301.10_crippled

I dont know why... havent tried a second attemp, but somehow this one sadlygot crippled.
It was in the first steps working fine, and also the KPaths/s made sense (roundabout 2900) then this...
after that I was no more able to rerender this until I was restarting MAX.


... just for Information purpose:

cheers guys!

I've the same problem as your last crippled test.
I've a GTS450 (for now) and with this test scene only with drivers until 275.33 it's ok, but with newer driver i've this problem.
Any tips?

[vlado]

You can try switching between the CUDA/OpenCL engines; also look for any errors in the output from the V-Ray RT render server.

I've already tried, but nothing!
vray have an error similar to:"driver api error"

That is quite something What is the number after the error?

Ok, vray version 2.30.02 and nvidia driver 301.42

OpenCL test: after few minutes the monitor goes black for some seconds, and after vray rt returns this error

these are all informations i've found!
I hope you can help me....we

[vlado]

That's the OpenCL error... what's the CUDA one?

FYI this rendered fine here on GTX 680 at 1080p.

Best regards,
Vlado

[3DKodo]

the second test is cuda...and this is the error returned
