@bev-sBev I have systems with multiple gpus that work well with Vegas. But they're different brands which makes it easier to know which is which when selecting them in the Video and I/O tabs or rendering. Do you see 2 distinct choices in the Video Preferences drop-down? And the I/O Preferences drop-down? I would suggest starting by trying to select the 6800M in video preferences and the other igpu (Radeon Graphics?) in i/o preferences if it supports decoding. Then compare with other combinations of selections. Try out all the permutations. You might also try testing without the external monitor and see if that changes anything. Also think about what video drivers you're using... that laptop sound like it is pretty proprietary in its architecture and you might want to test with the drivers from the laptop vendor's support page and see if they work best for you... looks like there's a gpu firmware hotfix over there too.

FYI, the updated benchmark results are online, not in that spreadsheet. You can go to data/filter views to sort by just AMD, etc.


@RogerS Hi i just had a look at the link, i sorted the list by GPU, are the 3070's separate from the others because of the - symbol?

Hi Gid, instead of sorting try going to data/filter views and creating a view to do what you want. I created a few already.

But yes, I think with sort they are out of order due to the hyphen. I just did some data cleanup for both NVIDIA and AMD so it should work better now.

@bev-sBev HI, i can't give you any tech details but you have an AMD 3950X, I have an AMD 3975WX, In my head yours is just the little brother 🤷‍♂️😂 You've mentioned a couple of times about poss getting a 3080, I have a 3090, same again just the bigger brother, I might be talking bollocks but i'm assuming Vegas will utilise them similarly ? 🙃🤷‍♂️

All the media in these pics were rendered orig by Vegas using Magix AVC/AAC 3840X2160, (NVENC)

This first pic is just normal rendering, no effects or crossfades etc, again using Magix AVC/AAC 3840X2160 (NVENC),

the CPU is at 24% & the GPU rarely goes above 50% when rendering, avg 30-70%, (faster ram might help but that's for another day)

How much of the CPU & GPU gets used depends on what fx's are added, in these pics i've added one random fx to each,

This one is an odd one, a cartoon fx that i've opened the CPU box to show, it's high

but if you look at all these other pics, the CPU is no more than 30%-ish, the GPU is normally doing the work

I did this partly for my own curiosity, partly because I'm not 100% happy with my pc + Vegas,

I know this is poss//prob totally useless info but i just thought i'd share before you splashed out on the 3080, also in the Benchmark test, the 3080's don't 'shine', for the price i suspect there might be better GPU's 🤷‍♂️

Many thanks, no it's interesting. Absolutely. There are so many variables to take into account. Memory seems to be a big one. Vegas appears to work better with AMD and OpenCL. Many thanks for getting back.

Many thanks! Sorry, I've been away and busy. Yes! I will check out the proprierty driver.

It was largely fixed by plugging in the monitor via the USB. I'l lsee about the fix for that. Many thanks for the help.

If there is one thing I've learnt - editing software is finnicky and sensitive. All of them.

My dream is (far) less time line crashes and buttery smooth time line scrubbing. I've yet to experience it - ever.

Yeah it can be really weird and unpredictable. I just installed Vegas on my desktop gaming pc as a backup in case my laptop dies and I did render tests to make sure it all worked. To my surprise with both using Vegas 19, my little Dell XPS 15 laptop with NVidia 3050ti gpu encodes *faster* than my gaming pc which has a desktop NVidia 3080 with both using HEVC NVENC! Makes no sense to me but it is what it is.

Effective use of your hardware and stability are not Vegas's forte alas, it's very quick and easy to use but the cost is slower performance and crashes. I've been using Vegas since version 4 but I've slowly been switching to Resolve which for me has been far more stable and makes much better use of hardware. Although even for that your mileage may vary, like people heap praise on Final Cut Pro but it crashed so many times on me in under an hour that I gave up on it, so who knows.

You have identical settings in Vegas on the both computers?

What is the CPU and ram on both?

Vegas settings identical on both. Laptop is 32gb with 11th gen Intel 8 core, desktop is 16gb with 10th gen Intel 8 core, but ram and cpu were mostly unused so they shouldn't matter too much in my case, gpu's were around 88% or so use on both, was using Voukoder. But I don't wanna thread steal, just made that post to show how unpredictable performance can be across machines.

I just updated BIOS and VBIOS in the ROG Strix G15 and got %50 better frame rendering on a complicated old project. Seriously. Way better time line scrub. 6800M Vegas seems to like AMD and crashes way less. It is totally finnicky.

I JUST GOT %50 BETTER FRAME RATE RENDERING

I updated BIOS and VBIOS on ROG STRIX 5900HX and 6800M, 32GB 3200 RAM. Just out in March 2022 update.

An old project, complicated, chroma keyer, moving text, multiple layers averaged 160fps for 30 min project. Peaked at 190fps.

Previously it peaked at 160fps and averaged 90fps.

I noticed the multiple layered chroma keya footage was eaten up like butter whereas it would usually stutter away and drop the frame rate precipitaciously.

The time line scrub was NOTICABLY smoother AND I previously had to render in two parts as it crashed continually at a transition - I have no idea why - obscure YT footage? It rendered in one go. I cried. Literally.

Will editing become a slight pleasure again?

Thanks for getting Vegas stable. (Bangs wood) Yippee!

low CPU use but higher frequency/IPC on 11th Intel Maybe, leading to faster processing. Also there's something weird going on with Task Manger since last update. I just transcoded via voukoder, simple cuts, and resolution change from 1080P to 720P, 3D graph in task manager was showing about 88% too. 3D should show processing power, but when I checked wattage draw and heat very close to idle readings, and the GPU fan didn't bother turning on.

Rendering speeds are VERY variable depending on multiple factors and ALL Editing Software has it's problems. AMD is definitely bettering their drivers and Vegas takes advantage. Still - Nvidia Cuda is king, allegedly.

On my widdle RX570 I got 35FPS on a project average. RX6700xt 90+ and 6800XT 135-160fps. It was a good comparison. Multiple tracks both video and audio 1080p footage with multiple effects.

As long as the frame size and frame rate are the same from source material to final render I find things extremely speedy - generally. Obviously 4K is a different story.

But yeh, expecting glorious speeds with new GPU's is not always the way.

If I was starting over I would go to DaVinci Resolve %100 according to render time reviews...but I always wonder in the real world.

Vegas is stable now and I cannot complain. Previously it was a nightmare of instability for me but that might also be partly Windows updates after they sealed off all those backdoors that were running amok - June 2020. Vegas just got better and more stable with every Windows update or was it Vegas update? I dunno - but once you've been to Iran and Lebanon strange things start happening to your computers.

Good luck with the powerhouse build :-)
