Heya
Arrr that gpu just keep on breaking on me hehe. What are the latest nvidia drivers that are working with GPU ?(nighties if possible)
Thanks, bye.
till now 295.73 on gtx 570 works fine with VR 2.20.03 (nightlies, but I don’t remember which one is)
EDIT 1: sorry, for me I was referencing to “stable_2.2”
The latest nVidia drivers work fine, however I’d suggest you use the “stable_2.2” builds and not the nightly ones; we are tinkering with the GPU in the nightly builds at the moment and it may be unstable.

Right - thanks for info. I’ll just wait for next release maybe it will work again. Are u also working with RT CPU too ? It crashes a lot lately or its just me.
Also do u want the dump file from GPU error?
Yes, they are both affected.
Also do u want the dump file from GPU error?If it is from the latest stable branch, then yes

Its the march 13 or 14 release… my GTX580M on laptop and GTX480 on workstation has that same error, my 8800gts was compiling it and I didnt let it finish… might let it someday hehe…
That’s why we are adding a CUDA kernel for the next update… it doesn’t need compilation.

CUDA Kernel???
What???
CUDA, like other GPU based renders have… most of the time… I think it will load quicker and work a bit smoother but I might be wrong 
I hope to use the next vray-rt gpu version with Cuda 4.x enabled, instances, GTX680 compatible (number of textures), high resolution textures.
So any ETA on when we can expect the CUDA kernel? Trying to decide between a 7970 and gtx 680. Sounds like now that theres a CUDA kernel on the way that the 680 will perform as well as it ‘should’
this is getting me excited..
please correct me if i’m wrong but are you saying vray RT will soon move away fron openCL and make use of CUDA instead?
Heya
What ever u do dont buy graphics card now…
There are still issues that we dont have answers for yet like :
http://www.chaosgroup.com/forums/vbulletin/showthread.php?67792-7-GPU-configuration-will-this-work-for-GPU-RT/page2 and http://techreport.com/articles.x/22653/7
Also I think it will be both cuda/opencl/cpu
We are not moving away from OpenCL and are still committed to supporting it. However for practical reasons we will be including a CUDA renderer as well. For the moment the advantage of the CUDA engine is that the kernel code is precompiled and it can start rendering right away.

In our tests for the moment, there isn’t a big performance difference between CUDA and OpenCL with V-Ray RT GPU on the same nVidia card. Like I explained above, we will be including the CUDA renderer for a different reason.

Huh I gotta say, CUDA =render, OpenCL = Crash =D I’m happy as long as at least one of modes work haha =D
