Vegas 15 Gained GPU Rendering, Lost GPU Accelerated Editing

fr0sty wrote on 8/29/2017, 1:29 PM

I'm using a GTX 970 GPU... really liking the added render speed from NVENC! However, I've noticed that when I look in the video tab of the settings menu, my GPU is no longer listed and it only gives me the option for OFF, unlike Vegas 14 which did see my GPU. Is there something set wrong or is my GPU no longer supported?

Not that GPU acceleration for timeline previews was working right in previous versions, though... some plugins (like color match) would bug out during fades if GPU acceleration was turned on, and it also caused a lot of crashes... so I guess no support is better than broken support. Hopefully it'll come back in working form in a future update.

I would try a GPU driver update. I read somewhere that worked. Kind of the opposite advice from before VP15.

Yeah driver, or possibly try running some of the NV Opencl demos. Sounds like OpenCL is not functioning well or Vegas is not seeing it correctly.

You could also make sure Luxmark works/ sees your GPU.

For my AMD cards, I install the AMD OpenCL dev kit just to make sure libraries are not left out in the reduced release driver.

You can also check to make sure the latest driver is actually being run by going to :

right click start > Computer Management > Device Manager > Display Adapters > GPU Properties > Update driver

Then "Browse my Computer" > "Let me Pick" > should list different drivers available on the system. Compare it the one running.

I have a GTX 960 and have exactly the same problem it shows up in Vegas 14 but not in 15. I only updated the driver about 4 days ago.

Do it again, as that fixed the problem for me. They just released a new driver on 8-26.

Yes your right there was a new driver. So I updated the driver restarted my computer and GPU acceleration is still set to off with no graphics card in the list. Annoyingly GPU acceleration is available in V14.

I've untagged Nick's post as the solution for now, until we can figure out what is causing this.

@Kraznet_UK Please report this, stating your exact O/S version, GPU model, and the driver numbers you have tried: https://support2.magix.com/customer/en/vegas/form

Hi Nick,

I'm pleased to say that I solved the problem of no GPU appearing in the list. What did was to open the Windows device manager and deleted the driver. I then restarted Windows 10 and it installed the Microsoft graphics driver. I checked and the GPU still wasn't showing in Vegas. I then downloaded the latest Nvidia driver and installed that. After the installation I checked in Vegas and the GPU is now appearing in the list. So we can consider that problem solved.
