Advanced Micro Devices, Inc. (Ellesmere) is your external graphics card. Make sure that is selected under GPU acceleration

Big thanks to: lenard-p and fr0sty! Thank you both very much for your responses, they both have been great help!

Hello, where is the I/O tab in preferences, and the Advanced Micro Devices, Inc. (Ellesmere)? I do not see these. I am on Vegas Pro 16.

Thank you.

This is Vegas Pro 17 only.

In the Video Tab>GPU acceleration of video processing

It is only Davinci Resolve that I have used that accelerates timeilne render/playback of default unaltered video using GPU 3D acceleration . It allows for smooth playback that's not possible at a given resolution/quality on other editors. So it can be done but isn't common for some reason

Timeline GPU acceleration only accelerates effects applied to the video, and only on the effects that support GPU acceleration (which is most of them).

Unfortunately, AMD cards cannot decode video for timeline playback in Vegas, at least not yet (apparently there are multiple NLE's struggling to get AMD decode working right). Nvidia cards, however, can, and Intel CPUs have "quicksync" decoding that is also supported in Vegas. Unfortunately, again, your system is all AMD (like mine), so we don't get the benefit of video decode acceleration in Vegas yet.

If you want to see how much your GPU is accelerating things, add some text or some other effect to the video, then play it back with the GPU acceleration turned on, then off. Note the framerate the video is playing back during both tests, you'll see a significant improvement by having your GPU enabled (assuming it isn't slower than your CPU at the same task).

If you get an Nvidia card or Intel CPU, you can go into the file I/O tab of preferences and set your card to be used for video decoding. Keep in mind that hardware decoding, by its nature (not a vegas limit) can only decode HEVC or H.264 video streams (2 of the most common formats captured by cameras today), so if you camera shoots another format than that, you won't see a difference over CPU decoding.

GPU Acceleration work best with GPU base OFX right? (EXP: Use GPU base color curve instead of the normal color curve)

But with this features on, I have to set my dynamic ram preview to 0MB (Yes, Zero) in order to get rid of the flickering/black preview. (Someone said this in the forum before, and yes it work.)

I cant have GPU acceleration & Dynamic RAM Preview in the same time. Possible to have both features working simultaneously in the same time without having that weird black/flickering preview?
