Nvidia GTX not recognised

I'm running the trial version of VPro14. GPU acceleration is shown as Off in Prefs and greyed out. There is no option to enable. Any advice appreciated.

Thanks.

I had this same issue with my GTX970, which left me quite infuriated after their system requirements stated supposed compatibility. I also wasn't able to use the New Blue FX or Boris plugins that used the GPU, which I had just paid a $200 premium to have included with Vegas. However, oddly enough, I opened the preferences menu again one day and there it was...

I would suggest updating GPU drivers, then a full system reboot. See if that helps. Also, check the system specs and make sure your card is above the lowest minimum supported line of GTX cards. I think it was 4xx or higher.

Working with my NVIDIA GTX560ti.

Thanks to all for your help. I've tried a re-boot and checked drivers but so far no change. I'm a Premiere Pro CC user and PP recognises and uses the GPU (Cuda). I'm just trying Vegas to see if I might run it alongside PP and then perhaps migrate fully. My background is in audio and I like some aspects of the Vegas interface. Probably not this version though. I do think Magix are to be congratulated on taking this on and hope for good things in the future.

Which GTX model and which drivers have you tried?

Thanks Nick

GTX980.

I used the update driver link in Device manager.

If you are using NVIDIA Maxwell-based GPUs or more recent models, try rolling back your driver to GeForce 337.88 or Quadro/Tesla 341.05 (an R340 driver) or older. These drivers can be found at: http://www.nvidia.com/Download/Find.aspx

I have too many up-to-date apps that take full advantage of my GTX 1080 to risk that, Eric...

Thanks all.

Driver version is 21.21.13.6909. Like Piotr I wouldn't risk going back to an earlier version as I rely on Premiere Pro for my business and it seems happy wiht the current set-up so I'm thinking Vegas is not for me at this time.

Here are two devices we have in house and how far we had to roll back for each to be recognized by Vegas and Movie Studio apps.

GeForce GTX 745 - driver version 368.69
GeForce GT 730 - driver version 369.09

As you can see, we did not have to roll too far back for these devices, but the current drivers were not recognized.

But Eric - how do you mean "being recognized"? My GTX 1080 IS recognized (it is evidently being used in both T/L playback and rendering); it's just net being used optimally (max. load in SONY VP 13: 54%, maax. load in MAGIX Vp13 and VP 14: 13%, max. load in Resolve: 100%). So What would I gain by rolling its driver back so far? I'm afraid it'd still work poorly in Vegas, while it most probably stop working optimally with new versions of software which is optimized for its use. Please try to explain, and I'd do this experiment for you!
