Problem with performance on Vegas Pro 18 (Build 527)

Dawid-Pietrzak wrote on 10/26/2021, 2:55 AM

Hi there,

My name is Simon I'm writing from our video editor account cause Vegas Pro has been registered on his account, as for me I'm working in the IT department.

Some time ago we bought Vegas Pro 18 currently working at build 527. We had some issues with a performance from the beginning while working on that but after my intervention, it has been fixed for quite a while. Since last week we have had major problems with Vegas Pro 18 performance and we don't know what is causing this problem. I've checked literally every possibility which could be causing this problem:

- from temperatures that are low for each CPU/GPU/Drives/MOBO,
- different version of drivers or exact same when PC was given when everything was working fine,
- finding if this is a hardware problem or Windows updates - none of them,
- maximizing potential from NVIDIA built-in Control Panel - didn't help,
- I've tried reverting the system to the last known good configuration it didn't fix this problem.

I found that some fonts (for example Dubai font) are causing this problem with the shadow being enabled. But as for shadow, it slows down completely on every font, in addition - PC isn't running even at 20% of its capabilities... Some fonts and at most shadows have a major impact on performance, on the below specs it shouldn't choke at all. I'm attaching global parameters, temperatures, dxdiag info and snap from the used font with enabled shadow. PS: All rendered files are on a local NVMe drive only the finished project is going to HDD.

I'm out of options. Please respond what I can do, thank You in advance.

PC specs on which Vegas Pro is running:
PSU: SilentiumPC Supremo FM2 Gold 650W,
MOBO: MSI B450 GAMING PLUX MAX,
CPU: AMD Ryzen 7 3700X 8core/16threads (4.2GHz) - watercooled with Corsair iCUE H150i Pro XT,
RAM: 32GB DDR4 3200MHz CL16 HyperX Predator,
GPU: Gigabyte GeForce GTX 1660 Super OC 6GB GDDR6,
CASE: be quiet! Pure Base 600, two fans + watercooled,
NVMe: ADATA XPG Gaming S11 Pro PCI-E x4 Gen3,
HDD: 2TB Seagate FireCuda 2TB.

Is the only media you are using generated text (titles & text)? Otherwise please share MediaInfo for your media. https://www.vegascreativesoftware.info/us/forum/faq-how-to-post-mediainfo-and-vegas-pro-file-properties--104561/

Setting dynamic ram preview to 0MB will reduce performance. Unless you are having errors related to it I'd keep at the default of 200MB or larger to use it as an automatic preview buffer. Active use of dynamic ram preview (highlight the timeline and shift + b) can be very helpful for text + pan/crop, which Vegas is slow at in the best of cases. It is counterintuitive how it can handle 4K compressed footage and then choke on a bit of moving text.

I'd also disable legacy GPU rendering unless there's a particular reason you need that.

Hi Mr. RogerS,
Thank You for your answer:

I turned off legacy GPU rendering,
Default 200MB option or even increasing it to higher value - did not help,
I tried that trick with highlighting timeline and shortcut "Shift + B" - also no improvement.

Below I post text information about rendered footage, on the other hand as a picture.

Any further options?

Playback the problem project and take screen shot of task manager showing gpu engines. and CPU, want to rule out the problem of the GPU decoder overloading

Some, including myself, had performance issues with VP18 b527, though I can't recall titles & text being mentioned as a problem on the forum before in relation to b527.

For those with performance problems with b527, a common recommendation on the forum at the time was to revert to the previous build - 482. Doing that certainly resolved b527 problems for me. If you want to try that out, build 482 can be downloaded from under point 6 in https://www.vegascreativesoftware.info/us/forum/faq-where-can-i-download-vegas-pro-and-other-vegas-software--104782/?page=1

If that works, the downside is that every time b482 is opened, there is a nag pop-up window to update to b527 - but just click on the 'later' button to bypass it.

I'm a little confused- so you have text overtop this video? I thought it was just text.

For the NVIDIA GPU are you using a recent driver? I recommend the Studio driver.
Under preferences, file i/o is the NVIDIA GPU set to the decoder? (NVDEC) Legacy AVC is disabled?

Beyond that if you want to do a ram preview for more than a second or two you need more than 200MB. Try more like 1000MB and then make a selection on the timeline and press shift + b. Before rendering I'd return it to 200MB or 0MB if you ever do renders with NVENC.
