In-process RT engine 3.30.01

[Donfarese]

Started this thread for me and anyone else that is having the issue of running the In-Process RT engine with two different Gpus in there system. I have a AMD W7000 for my viewport/monitor & a Titan X for compute rendering. With the new In-Process RT engine (which sounds awesome) this type of setup will not work. I am currently running 3.30.01 in the old way of Out-Process command-line which kinda sucks ( you have to Manuel start RT from command line every time first use), plus you get none of the benefits of the In-Process RT. I have tried turning my Titan X into a TCC, which doesn't seem to work right for me. It does something funky with the GPU fan that it doesn't speed up with temperate rising so the GPU starts really heating up. I tried using a fan Software to set the fan and fan curve myself but the GPU in no long recognizable to anything but RT in TCC mode. So I put it back to WDDM. Want to see if anyone has any ideas what to do?

Do I run a Tesla driver instead in TCC mode or do I still run the Titan X Driver?

As I said befpre, this problem is not caused by V-Ray (for example, the same setup does not work in IRay or any other in-process GPU render). You know what are the workarounds for the moment (start V-Ray as a server, or use TCC). If you have troubles with the TCC mode it will be best to send them over to NVidia, since they are more familiar with their drivers behavior.
If we find any workaround that can be applied, we will let you know.
Also, AFAIK for Titan X you should use Titan X driver (no matter TCC or WDDM).

Yes Blagovest, you guys gave me two options to work with, I was not trying to look like I was disregarding your solutions. I appreciate all the help, and have been using the V-Ray as server option so far. I was merely posting this thread to see if other studios or there IT departments have come up with better or different solutions. The more minds the better

I'm pretty sure running the Titan X in TCC mode is not officially supported, I have seen on other forums it is possible to flash its bios and make it behave like a quadro M6000 though, but I would not do that unless you know exactly what you are doing.

Is there a link explaining this new "in-process" engine and what the differences are compared to the traditional one. Also will it still be possible to use the Vray RT render server (spawner) on supported machines?

Not yet; still working on the docs.

Yes, of course.

Best regards,

I am running in RT mode with TCC again. It is easy to put the Titan X into TCC mode just like the Quadro, but you cannot then monitor or change fan settings, OC, or anything for the card, it just runs stock everything. Now to get it cool, which was my only concern, I am just going to add an Hydro cooler to the card which should bring the max temp from 83C max down to 55C max.

In-Process seems to load the scene and start render much faster, also it caches textures onto the video card, so next time you render you don't have to wait for the textures to be loaded again which is a huge speed up. I'm sure there is much more to it but Vlado will have to explain that.
