GPU 5700xt Not showing In GPU Acceleration [Vegas 17]

Former user wrote on 5/7/2020, 6:56 PM

I have been rendering my videos on my 3700x, but heard recently that rendering based on GPU might speed up the process. I never thought of it as the there never was such option. Googling on how to enable GPU encoding, i cannot follow the process as the GPU (5700xt) just does not show up on my version of Vegas (build 421). It only shows the options "Off" and "Optimal-Advanced micro devices Inc. (gfx1010)". How can i add my GPU to that list?

The GPU i have in case it matters is a red devil 5700xt.

Kind regards.

I think gfx1010 is the internal name of the Navi 5700xt compute engine... try selecting that. Then look at Windows Task Manager's performance tab and see it there's gpu activity while Vegas plays or renders mp4 stuff.

The Radeon RX 5000 Series GPUs have the new VCN ASIC which is not yet supported by VEGAS for hardware decode/encode. VEGAS only supports the older UVD/VCE ASICs as found in Radeon VII Series and earlier.

Edit: Actually I think you are confused between hardware acceleration and hardware encoding. The options "Off" and "Optimal-Advanced micro devices Inc. (gfx1010)" relate to GPU acceleration of video processing on the Preferences > Video tab. That uses OpenCL to accelerate your timeline etc. and DOES work with the RX 5000 series. But it has nothing to do with whether AMD VCE appears as a rendering option.

Furthermore, "Optimal-Advanced micro devices Inc. (gfx1010)" is your GPU under a different name. My AMD VEGA64 appears as "Optimal-Advanced micro devices Inc. (gfx900)".

This type of post is going to become increasingly common as users buy RX 5000 series GPUs or computers that incorporate them, and then realize that hardware decode/encode does not work with them. I think this should be clearly stated in the marketing information. When users read "Take advantage of hardware acceleration from modern NVIDIA and AMD graphics cards" and "AMD/ATI® Radeon with 4 GB and VCE 3.0 or higher" it's very easy to assume that the latest mainstream AMD GPUs will be supported.

[Edit: It turns out that this is wrong, and that NAVI-based GPUs ARE supposed to be fully supported now. See this comment from a VEGAS developer.]

@NickHope I agree. I have thought about buying an AMD RX5000 series card, but haven't as just yet because VP presently doesn't support it. I'm still using the RX480.

I hope RX5000 series will be supported in the future.
