How to configure graphics card? OpenGL Crashing error w/ Titan X. considering k6000

[emartin8907]

Hi,

at my work we are experiencing some crashes with our Titan X video cards. 'Nvidia OpenGL Driver detected problem with the display driver and is unable to continue' Error code 8

We are pushing around some heavy models (CAD cars)..

Machine is 32 core, 32gb ram, one Titan X.

We are upgrading ram and considering K6000 as they have optimized drivers- my question is would it even be worth switching to the k6000? Would we see more stability? Are there any settings we should try first with the Titan X?

Thanks,

Eric

Are you using the cards for RT GPU or you just need a Maya viewport performance?

[emartin8907]

Just normal viewport performance. Not sure if this is a vray thing or Maya thing or what

It looks like a graphics driver issue. Maybe try a driver from a few versions back.

Best regards,

The crash you are having may be a vp 2.0 crash. I know I get that from time to time especially when I have very heavy CAD car scenes. The legacy viewport can offer some better stability when you keep hitting this issue but it's not ideal because the legacy viewport is old and in the process of being phased out. This is almost definitely not a V-Ray issue especially if it's still happening when you're not GPU rendering. I would recommend you log this with Autodesk. Try to find out why your driver is crashing when using heavy scenes in VP 2.0. Autodesk will most likely tell you are card is not supported by Maya:



Out of interest are you getting good performance with a Titan X with heavy scenes? in particular when you have lines/wireframes enabled. I looked into a Titan X when they came out but came to the conclusion that I should stay way clear for professional work, esspiecally CAD car work because Titan cards are primarily designed for 4k gaming and their drivers are not optimized for CAD work. My research indicated that a Quadro k2200 would outclass a Titan X on VP performance for about £300-400 less than a Titan.

I think Titans could work out to be very cost effective for GPU rendering or any CUDA enabled application. I have a GeForce 960 for gaming at home that does pretty well with heavy Maya scenes but from what I understand even if the hardware has superior spec with a gaming card the driver will throttle the performance of the hardware for CAD/heavy polygon scenes and animation playback.

If you have clients relying on your hardware for professional work that involves CAD data I would strongly recommend you consider a Quadro.

Hope this helps

Thanks for the detailed post Lee!

That's interesting legacy veiwport offers more stability, it is so painfully slow in comparison.

I'm getting pretty good performance with the Titan X on my own workstation, very minimal crashing now. I'm using RT and am toggling between wireframe and shaded and textured and it's moving the data around no problem for the most part. one of our artists was experiencing a lot of crashing (open gl error) he switched to a k5200 we had sitting around and has had a lot more stability. I think we are getting one K6000 to test and compare against the Titan X I will be sure to update here our experience with that.

Yea I guess just because the Titan X has better numbers that driver wizardry really matters massive CAD files like these.

I'm curious how you figured a k2200 would outperform a Titan X for VP?

Thanks!
