Very good, thanks for those tests. It is sad to see that the performance is still not there though.

Here is my test with (3) GTX Titans, not overclocked.
36.4 seconds

I have a fourth Titan to install - later. I LOVE these things!

Here is the result with (4) GTX Titans, not overclocked.
33.7 seconds!


Yowza! That's fast!

[askhamdesign]

Very quick, wish I could afford just x1 titan! Would of thought x4 would of been a bit quicker than 3 seconds of the x3 titans?

Could be that the CPU can't feed 3-4 Titans fast enough to stretch their titanic legs?

Here is (4) Titans with V-Ray 3.0 Beta.

22.3s

Wow, V-Ray 3.0 shaved 33% off the time. That's definitely significant.

I did notice it's a bit nosier than with 2.4

The first beta was bugged in that regard; 3.05.02 fixes it.

Ahh, so you did. Sorry I didn't check back far enough. So on exactly the same rig V-Ray 3.0 beta knocks nearly 6 seconds off.

it seems so, but it's still a gain of 21.5%.

I recon that if we had a longer rendertime scene, it might be more apparent, I don't know if the timer really starts when the image start to render, or if it's counting the time to transfer the file to the GPU and initialize the render etc.

I know for a fact that if you have a big big scene that take 2 minutes to start rendering, and I set 3 minutes in the max time used to render in RT production, your first image will only be calculated for 1 minutes and the next one will be for for 3 min...

if you compare the two images side by side (2.4.04 and 3.05.02) there are some difference with the two images. I'm not exactly sure what.

The first beta was bugged in that regard; 3.05.02 fixes it.
