Hi thanks for the reply. I'm at work and only got my laptop so can't check with Mediainfo. It is gopro footage at 5k 30, insta360 at 4k 30, drone at 4k 30 and nikon at 4k 30. I've got plenty of HDD space (100gb).

I was just able to render on my laptop which is much less powerful at 90kb max and 75 constant onto my external HDD. Laptop runs smooth as too, bizarre.

I don't know if I've seen any other 9070 XT users (you may be one of the first!) on this forum. It's possible there are driver issues if these issues aren't widespread among AMD users (haven't seen many complaints) as these types of media really should work.

I assume the GPU itself is fine, has enough power and cooling and passes benchmarks (GPU Mark, etc.) without any issue.

Without having actual footage to test on my all AMD computer, it is hard to say. I have the RX 6700XT and am using driver 25.3.1.

As for uninstalling AMD drivers, I use AMD's Cleanup Utility.

Ok I might try a previous driver, I'm using 25.3.2. Tried a video again last night, tons of errors in the render. I rendered without a graphics card (bloody slow!) and its fine.

Do either of the projects in my signature render well with the GPU? If so it must be something specific to this project. Hopefully we can narrow it down.

Hi Roger. I ran that and no problems (was really slow though). I also ran my project at your bit rate and it was fine. Soon as I raise the bitrate, problems start happening, strange

Thanks for checking. If a different driver doesn't help I'd report it to AMD and VEGAS support and let them know about the issue at high bitrates.

The default bitrate is pretty high so maybe try that for now until the issue is resolved?

Yeah I'll experiment with bitrates. I remember on old cards I couldn't go over 50 or it would do the same. Thanks for the help!

@OTBW which older cards are you referring to? Thanks!

Hi.I once had to work on a workstation provided by an employer that used a Gigabyte RX 5700 XT AORUS, and the experience was terrible. I almost gave up on using Vegas Pro, thinking the issues were with the software itself. I constantly dealt with unexpected crashes, which forced me to save my projects constantly—and even then, the autosave often missed my latest changes. My final renders would also have random black sections, which was incredibly frustrating.

Later, when I started working on my personal projects, I used an Intel iGPU, and everything was totally stable. I then upgraded to an Intel Arc GPU, which was about 95% stable—just the occasional render glitch. Now, with the latest generation of NVIDIA GPUs, I haven't had a single complaint.

So my question is: does Vegas Pro historically have poor support for AMD GPUs, or is this more of an AMD driver issue?

@RobertoL not that I am aware of. I had a RX480 8GB and then updated to the 6700XT and have had zero issues with either the drivers or the cards themselves. There are others (although rare) that have other AMD cars and are editing right along.

Just an observation of forum comments over the years. Around 10 years ago I recall that there were more problems with NVIDIA GPUs than AMD GPUs. I was happy at the time because my computer had an AMD RX 480 GPU. But that situation seems to have somewhat swapped places over time because more issues seem to arise these days with AMD GPUs than NVIDIA GPUs. Of course, this is not in all cases and not with every usage in Vegas Pro. In writing the above, I am only indicating a maybe subtle trend that I have noticed over the years.
