When it happens, check Windows Task Manager in case multiple instances of Vegas are causing that behavior. Also check if WindowsUpdates or Anti-Virus Scans are doing it.

I've noticed the same thing but have no solution. It is especially "slow" if you do a "save as" with copy files ticked for archiving. Once the file copying is completed, Vegas opens the newly saved project and does a media replacement. Once completed, it's really, really slow. At that point, the only solution is to close Vegas and relaunch the project.

@wwaag You have GPU with 4GB Vram, OP 6GB, Is your Vram full, swapping out to shared GPU memory?

Do you feel whatever the problem is , it has nothing to do with Ram and Vram based on your observations?

I've found that if the 'Create Project Collections' switch is turned off in the Hub Explorer, the sluggishness after saving no longer occurs.

@Former user

It's probably just 4GB. I recently installed an A380 for testing replacing my old 1050ti. The issue of "slowness" existed with both cards. My suspicion is that it has nothing to do with Vram, but who knows???

@Dexcon

I'm not using or even logged into Vegas Hub. I did turn it off as suggested and will test upon return from a two-week visit to Arizona.

This aspect is not a cloud login-required function as I understand it - the project collection thing is local to your computer.

Have a great trip.

Here are my settings. I wanted to prove that a few days ago everything was fine. The only thing that happened - it's been happening for 3 years and the support can't fix it - is the ptogram freezes, stops responding, and is fully tested when turned on. I have to reset all my preferences, eg annoying F12.

Did resetting your preferences help?

Dynamic ram preview is set higher than I'd recommend for a 32GB system. Can you watch overall ram usage while you are using the program (task manager/performance in Windows) and see if there is a memory leak?

@Piotr-Diszer,

Thanks for the screenshots
- About screenshot1: set your Dynamic Ram preview max back to the default setting.
- About screenshot 2 : It looks if there is no QSV (iGPU 630 from your CPU i9 9700) available.
That is a Windows problem and to get it visible for Vegas you have to allow it to show up in the BIOS of your workstation.
- After done this all you have to do is resetting Vegas to its default setting from the start

Thank you J-V, and where is this function in the BIOS you mentioned turned on? Have a look at the UEFi BIOS?

Does the installed Nvidia graphics card not automatically disable the graphics from the processor in the BIOS?

My laptop before the one I have nowa nd the one from my signature had the same problem The former I found myself and the newer one I asked my supplier to do that for me. Unfortunately, my memory is not so good that I still know exactly where to find it in the BIOS.

No, with me the default Vegas installation gives the best results for me and that are

Driverversions you can see on my signature

The Intel igpu is normally enabled in bios by default but the motherboard & laptop makers construct their menus differently... the manual for your motherboard is what you should consult if you want to do that. A quick test to see if it's enabled in bios is to plug your monitor into the motherboard hdmi port and see if boot up messages are displayed and you can boot into Windows. If you can, the igpu is enabled in bios.

If the igpu is enabled in bios but does not show up in Vegas video or i/o prefs, the Intel graphics driver needs to be installed.

I like to look for that on Control Panel/Task Manager/Display Adapters, much easier for me

None of the actions brought results. The program after a few minutes reacts slower and slower until it dies. Task Manager does not show any overshoot or approaching full memory or CPU usage. Will someone help? Has anyone solved this problem?

I've had the same problem since Vegas 18 or 19 but I'm using 20 at the moment and it's still a thing. This issue is present on a wide variety of computers (both AMD and Intel) I've used. I always thought it was a ram thing that actually may be linked to the type of footage being using or maybe even the frame rate it's shot in, but I really don't know. What kind of footage are you editing?

It was so bad for me that I just replaced my computer because editing was taking far longer than it should. It would get to the point where even deleting a single clip from the timeline would take like 15 seconds.

For the past year or two, I've dealt with the problem by breaking my projects in to smaller pieces and then just combining in to one later (also making sure to get rid of all unused media from the project). This helps DRAMATICALLY. The more media you have in a timeline or project, the more this issue is present.

My new build is an i9-13900KS with 64 gigs of ram and an AMD 6900xt (upgraded from AMD 2700x, 32 gigs ram, and AMD 6900xt). With the new build, it's definitely not as noticeable. I can edit for much longer before it starts to become noticeable, and then a restart fixes it. But I feel your pain.

@Piotr-Diszer

Could you post a snapshoot from the windows task manager, when the problem of the slowdown occures?

I am sending graphs from the Task Manager. But here are quiet readings, something is going on in the program. The most common way the program saves the backup veg.bak project file is the freeze program
