What settings to utilize nVidia 4090?

mprinda wrote on 1/18/2025, 9:13 AM

Hi all.

I use Vegas Pro (20.0, build 411) occasionally for simple video editing for later upload on Youtube, I am not very into the topic, but I noticed quite low GPU 4090 usage during encoding videos (mostly 4K NVENC). I would expect significantly higher GPU usage. I am quite happy with the performance but maybe I could be more happy :) What is the best setting of Vegas and codec for such GPU, please?

Some video with Task manager during encoding is here:

Thank you in advance for your answer.

@mprinda Hi, I don't think you're going to improve on that, my CPU & GPU look similar when just straight rendering (they can look different depending on alterations & fxs added but I don't see any added on your timeline events..)

The pop-ups hide the project size at the bottom of the preview window but In your video the export settings don't show a = sign next to the render template, this means you're not rendering the same as the project aspect, (I'm guessing the project size is the same as the media size) At 60fps true 4k I wouldn't expect better performance.

PS. try one of the render options that have an = sign next to it, you'll get a faster render & see if you get an increase in the CPU / GPU use in Taskmanager.

The GPU has a separate chip for video encoding to the Ray tracing and others cores used for gaming, many cards in the 40 series use the same encoding chip.

Feel free to try a benchmark in my signature to compare your system to others with a project that challenges the GPU.

@Gid Thank you for your answer. I will try your suggestion, now I know what "=" sign means. I think I made my profile by modifying the one with "=" sign by changing the FPS from 30 to 60. I was wondering if there might be setting to be able to utilize GPU to 100% or so 🙂

@andyrpsmith Thank you for your answer. I kind if knew this and because if that I was expecting to see the encoding core close to 100%.

mprinda wrote on 1/19/2025, 1:28 AM

@RogerS I will try, thank you 👍

If you want 60fps output I'd change the project to 60fps instead of just doubling frames at the render stage.

VEGAS has other bottlenecks so you'll never see 100% in encoding. The encoder is waiting on other processes to finish.

@RogerS Usually I edit clips from GoPro which is set to 60fps and from nVidia Experience (now nVidia App) also set to 60fps. Yester it was just random clip of my desktop captured by nVidia app (4k, 60fps). If this looks like normal behavior then I am happy. I was just curious if there could be something set wrong on my PC 😉

RogerS wrote on 1/19/2025, 2:44 AM

If that's the case then be sure to also set the project (alt + enter) to 60fps and then pick a = render template to match.

It's likely normal behavior but if you want to fill out a benchmark (I recommend the VP 20 one) I'll take a look at the results with you.

@RogerS benchmark done, looks OK comparing to the others. Thanks for this comparions table. I tried also CPU accelerated render but Vegas crashed. I will try later again.

@mprinda Hi, I missed the version you have, there was quite a big improvement with playback, stability & speed of render with Vegas Pro 21 (build 300) esp with MP4 HEVC, GoPro's only produce MP4 HEVC files rather than the old MP4 AVC, these HEVC files would stutter in VP20,

I personally noticed a big difference with VP21 (300) onwards, VP18, 19, 20 crashed quite often (esp with added fxs) & now it hardly crashes at all (when it does crash it's because I've blown it's mind swapping out fxs too quickly etc🤦‍♂️😂) , MP4 HEVC's play & render just like MP4 AVC's, I used to convert GoPro HEVC to AVC so they work well in VP, but now I've swapped my phone settings to HEVC so they match the GoPro HEVC, therefore I now only use HEVC.

I think like me you bought a decent PC & was wondering why such a powerful machine wasn't just blasting through the render, I can't comment on that really but like I say there have been big improvements & more upgrades are promised, so I suggest you try the Trial of the latest VP22 version & see if there's much difference, I think you'll find there is, I now don't notice any difference between AVC & HEVC 👍

You can click your icon at the top of this page - My Profile & fill in your Signature with the full name of your CPU, GPU & amount of RAM, also inc the Windows & Vegas version, this will then show at the bottom of your comments 👍

Also try the Studio GPU driver if at present you're using the Gaming driver.

Sorry to hear about the crash.

As with Gid I found NVIDIA decoding finally working better towards the end of 21 and now with 22. I would consider doing the trial of 22 (or save up for 23 when it comes out) and see how the performance compares to 20 for you. You have a great system and as VEGAS improves it will make better use of the hardware.

No problem with the crash, it happenes from time to time. I will try the latest version probably in February when I have more free time.

@Gid signature filled. I prefere gaming drivers over Studio ones since I use my computer mainly for simracing.

andyrpsmith wrote on 1/19/2025, 11:07 AM

I have been a gamer since 1980's and have used both gaming drivers with virtually all versions of Vegas since 13 with no issues, I have also used Studio drivers with Vegas and with some games with no issues. Some games however need optimised drivers to perform at their best.
