You can save custom templates for Voukoder so you don't have to go into customize settings each time.

Vegas using some flavor of OpenCL? Odd that it would skew so hard towards AMD otherwise?
Unless things have changed Vegas is optimized for OpenCL 2.0 Framework, that's a standard from 2013. Maybe the newer Nvidia GPU's that work so well with OpenCL need a newer version of OpenCL to work efficiently and Vegas is too outdated, which is giving modern AMD GPU's a big lead
@Former user Don't have info on Vegas internals but I've seen developer comments here saying they work with Intel and AMD, pay for their support, and that they try to implement what their libraries support. The AMD video specs I've seen indicate that older AMD boards like the rx590 support OpenCL 1.2 and that RDNA like the 5700xt supports OpenCL 2.0. TechPowerUp indicates RDNA2 like the 6800xt supports OpenCL 2.1. Intel seems to be somewhat more advanced supporting OpenCL 3.0... I only checked as far back as the hd610 but it looks like they update OpenCL across their entire line via their driver updates.
Nvidia started out with OpenCL like everyone else then dropped it for a number of years when they adopted a proprietary licensing scheme for Cuda to milk the game makers. During which time Vegas stopped working with Nvidia boards unless users were able to keep an older driver going. Nvidia apparently reversed that in recent years but I don't know if Vegas now pays for Cuda or gets by with Nvidia's OpenCL implementation which I suspect is intentionally limited so as not to compete with their Cuda api licensing.
Were Nvidia and Intel have been outstanding in recent years is in their support of open source projects like ffmpeg. AMD had really lagged there and is not well supported by their libraries. Which is why ffmpeg and all the apps that are powered by their libs, like Resolve, do not perform as well as with Nvidia and Intel. I find that Vegas performs much better than any of those with AMD gpus. I use ffmpeg allot and really wanted to get a high powered Nvidia gpu for it but the cost differential has been too high and the availability too low.
Regarding 4k60 hevc, I've never shot with that the way I do with 4K30. Which I've been doing all the time in recent years for performance and media reasons. Which AMD gpus are killer with. And it was been my belief that the visual difference wasn't noticeable. But I did a test and the 4k60 avc looks better to me. And more importantly, my wife thinks so too. Don't have a version of RedCar shot in 4K60 hevc but I did post my YouTube test shoot and a Vegas project zip if anyone wants to evaluate for themselves. See:
If Vegas finds a way to handle 4k60 hevc as well as it does 4K30, I'd be inclined to shoot it more.

I had a 10% OFF Best Buy coupon, so with sales tax I got a 6800 XT for <$1300 US and will sell my VEGA 56 for approx. $800 US, making the cost of the upgrade approx. $500. I'm using a 0% for 18 months BB card so I'll pay it off when I hit my peak editing months. IMO now is the time to sell old GPUs since miners are snatching them up at extreme prices... I got the VEGA 56 for $200 just before the mining craze. Had I known I could have made $600 per GPU I would have gotten a bunch more. If you have any Radeon VII's, they are selling for over $1500 US right now!
