Thanks for the reply, those settings increased the FPS to 13 FPS, but still a lot slower than my previous graphics card.

I believe in a previous version of Vegas to render using GPU only, we could set the "Dynamic Ram Preview Max" to 0? I did this however it slowed down even more after that, running at 8FPS

What were your benchmark total render times? Did you do a 4K or HD render? Try filling out the form and we can see what's what.

Zeroing out dynamic ram preview will further reduce performance though potentially avoid artifacts when rendering. I'd keep it on defaults.

I assume the NVIDIA 3060 is selected in preferences/ video?
I assume the NVIDIA is also doing decoding in preferences/ file io?

The GPU can do decoding, timeline and Fx processing and encoding. The CPU does everything else. If the GPU is just waiting on the CPU then that's your limitation.

If you don't think the GPU is functioning properly try a free tool like 3DMark (download through Steam) and test it. Ensure you are using a recent NVIDIA Studio driver.

It struggled a lot with that benchmark test, I've just submitted it now. I think it's likely the CPU like you said, it's well out of date, going to upgrade the motherboard / cpu / ram tomorrow.

All the settings you mentioned in the most recent post I've already set, no change. I highly doubt its the fault of the GPU I know lots of people using this model perfectly fine, but not on 10 year old CPU / Board

Definitely the CPU... Those bulldozer cores were notoriously weak, don't support multi-,threading either.

This one has multi-threading, it's the first series to introduce it for AMD. Was decent in it's day and still did everything fine up until now with gaming in 1080, just can't handle 4k video rendering at all.

I will see how things go tomorrow with a latest gen AMD CPU and report back, but it's looking like the lesson here for me is swapping GPU alone once the CPU is 3+ years out of date is a waste of time, pretty sure the 1050 Ti wasn't even running to it's full capacity let alone the 3060 Ti.

Hi Roye, thanks for trying it. I agree these times are not impressive for such a GPU. Do let us know how a newer AMD CPU works (would be great to see your benchmark time improve!) My times with a 2017-era CPU and GTX 1050 mobile GPU were about twice as fast as what you're getting so I agree with not putting more effort into this aging system.

Also for updating VEGAS, I'd keep the software within 6 years or so of the hardware as it can't do what it needs to with the older hardware.

@RoyE What Vegas and build are you using? Before (I think) the final build of VP18 there was a slow NVENC problem with 30 series GPU's, so that would make sense when nothing changes except your GPU and you go from a older less powerful GPU that was compatible with Vegas and a more powerful GPU that is not compatible with certain versions of Vegas

It's 19.651 so not the issue here. See the benchmark result:

https://docs.google.com/spreadsheets/d/1b3ggVifKsuT-cp2kQHjum_KnQ4-2jBmUIvzmu7BQZ34/edit?usp=sharing

My only recommendation here would be to try it with lower dynamic ram preview amounts- 18400MB is high for a 32GB system.

Half way through the new build now, will be using a AMD Ryzen 5 5600 6 Core 12 Thread 4.4GHz with 32GB DDR4, will be interesting to see how it turns out, should be finished it tomorrow or Friday.

OK the results speak for themselves. It's ultra fast now! Thank you for helping me identify that the CPU was causing a massive bottleneck.

Benchmark difference:

The original 10 year old CPU gave me the following results on the RogerS benchmark test. Both are using the 3060Ti.

05m : 07s render time with 0.54 frames per second average with the previous 10 year old CPU.

Results with the New CPU, New Board, 32GB DDR4 added:

00m : 14s render time with 11.7 frames per second average!

My regular workflow changes:

Comparing to my old CPU that was rendering my normal 4K projects at 12 FPS, and the 1050Ti before that at about 16 FPS, with the new CPU it's running at 32 FPS average.

There might be more gains to be had with more RAM, so I'll add more in a couple of weeks time and raise it from the 32 now to 64GB, I'll also install a CPU water cooler (fan cooling at the moment).

Thank you for helping me solve this issue :)

Wow, really stunning improvement! Almost seems too fast, that's correct for UHD with NVENC?

Anyway good job choosing hardware that's up to the task of editing video and now you can get back to it.

If you're not hitting thermal limits under load (try a render with Mainconcept) you can keep the air cooler. For ram probably won't speed things up unless you're hitting ram limits already. I did go to 64 myself as I plan to keep my system for years.

Can you retest the UHD 3060 render and confirm the file is the full project length (not just the preview section)? Far faster AMD CPUs and GPUs are closer to 51 seconds. Nobody is near 14s for the render.

I just ran it again twice, I've attached the entire process, can you double check it's all set up as expected?



 

Ah sorry, I was only rendering the short section as you can see there.

Can you delete my old results and I'll run the two with the new CPU again?

Here is the correct results rending the entire project for the 3060 Ti on the new CPU

10.20 FPS @ 41 Seconds video time
01m : 15s Total Time

All the previous tests were just that little snippet, so you can see just had bad the old computer really was, probably would be similar frame rate but 4-5 times the length.

There might be more gains to be had with more RAM, so I'll add more in a couple of weeks time and raise it from the 32 now to 64GB,

@RoyE Hi, just had to mention in case you weren't aware, RAM has a speed, My motherboard will only allow up to 3.2Mhz but to have the amount of RAM I wanted I had to go for the lower speed of 2,666Mhz.. Not sure if that was the right decision & I don't know if that affects my benchmark speed but it it is what it is so I just thought I'd mention it before you bought more..

Of course, happy to do data cleanup. Thanks for double checking.

Thanks, I didn't know, I'll do some research on my motherboard and online before I decide to buy more, it's a fairly low end motherboard so this is good to know before I dive in

@RoyE 👍

If you right click on the Taskbar at the bottom of your window - Taskmanager it'll show you what you have already installed 👍
