Vegas 20 gpu acceleration make render worse

You can try one of the benchmarks in my signature and see if it's slower than similar hardware.

In preferences/ video why is GPU acceleration off? Try leaving dynamic ram preview on default values. (5 percent)

Is your iGPU enabled in bios? It can speed up decoding and QSV is fast at encoding.

Hi, already tried different benchmark and my result was everytime from 6 to 10 times slower then other people with similar hardware. Gpu acceleration is off because the problem only start when Is on. Already tried every % of Dynamic RAM. Igpu enable or disable male no diff, already tried.

@WarThomas46 Try the Studio driver instead of the Game driver. you have to install it.

BTW. pressing Alt+F9 records & stops recording the screen without having to open GeForce Experience, Alt+F1 captures a single image.

Thank you for your answer. It was a fresh install so i forgot about the drivers and It was the first time i used shadowplay to record (i use obs). I tried to install the studio drivers but nothing happened. I also tried to install the cuda kit drivers

Something is very wrong if it's 6-10x worse than others.

You need to enable the iGPU, it's critical for HEVC and other media.
For dynamic ram preview and testing I'd put it at 5%. It takes away from the total ram VEGAS and Windows has to use.

Next try to reset VEGAS. https://www.vegascreativesoftware.info/us/forum/faq-how-can-i-reset-vegas-pro-to-default-settings--104646/

For NVIDIA you seem to have some kind of problem if "nothing happened" when you installed a new driver. They have a cleanup tool here. https://developer.nvidia.com/cleanup-tool After the cleanup try installing the latest studio driver. (I have two NVIDIA systems myself)

hi, sorry for the wait. Enabling the igpu reduced render times, but im still a lot slower then all the others in the benchmark... here is my settings

@WarThomas46 Dynamic ram preview is too high- you are past the point at which it speeds things up. Now it's taking ram away from bigger projects that may need it. Try 5% for now, or 10% if you really want to make ram previews.

You have the iGPU and GPU set up the opposite from what is optimal.

Have the NVIDIA GPU enabled in preferences video.

Have the Intel UHD 630 doing hardware decoding in preferences, file io. (raw decoding doesn't matter).

Don't tell me it doesn't make a difference, do the benchmark and report the exact times and preview framerates you get this way and the way I recommend.

yes now i make the video, i use your vegas pro 20 ad benchmark

Sounds good, I'll look for it tomorrow.

done, tell me what you think

Please close the capture utility, don't touch the computer and let VEGAS complete the render. I suggest trying it 2 times each way and report the best times using the benchmark form.

The last setting are right? i make the benchmark with all app closed and i give you the screenshots

The settings at 6:21 look fine. For file io, keep the settings on defaults. Legacy or not legacy HEVC makes no difference here as the media is not HEVC.

RogerS wrote on 12/4/2023, 11:56 PM

Also, can you share a screenshot of help/ driver update in VEGAS so I can see what the iGPU and GPU drivers are?

is this the right page?

RogerS wrote on 12/5/2023, 10:32 PM

@WarThomas46 Thanks, that's the right page. You might check and see if there's a newer Intel driver for you: https://www.intel.com/content/www/us/en/support/intel-driver-support-assistant.html

Your NVIDIA is up to date.

------------------------------------

So for your renders, the screenshot on the left is with the settings at 6:21 in the video? It's hard for me to understand what is what with no text explanation.

Anyway a time of 7 minutes is far too slow for your good hardware.

Did you try the reset I recommended before (and clear the cache?) Sometimes that can help if VEGAS stops working properly. You won't lose any projects or data. Custom layouts can be restored. You can also backup most of your settings if you choose to with export preferences.

yes i checked your link and all drivers all up to date. Also i tried reset but nothing changed. I dont know what is happening... I think there is some type of incompatibility that i can recognise and also vegas assistance cant...

also, can ram speed be a problem? Do you ever heard of that type of problem? Can my gpu encoder/decoder be faulty? How can i check it?

RogerS wrote on 12/6/2023, 10:11 AM

I am not sure what's wrong here. VEGAS and the project are on the SSD (c:), right?

Did you close every other program that could possibly conflict with it?

I don't think your GPU is faulty as the Intel iGPU shows decoding activity and the NVIDIA shows encoding and 3D activity.

Your CPU seems to be at the high 4.9 GHz clock speed for the whole render and not slowing down due to overheating (though I am not sure of that as the video doesn't show the whole render).

If you wanted to look at the system during a render with HWInfo64 you can see if any cores or the GPU overheat and throttle (slow down).

Please try it and see if there are any clues.

I doubt ram speed makes much of a difference.

In VEGAS preferences/ video, you could try reducing the number of threads to 16 and see if it helps.

If you want to try other benchmarks and see if the system is working right the free 3DMark is a good test for CPU and GPU in general.

If you see any clues in HWInfo or 3DMark please share a screenshot.
