Maxxed Out Hardware – Vegas 22 Still Lags
Wow! It’s been YEARS since I’ve been a part of this forum… so great to read so many kind and helpful posts. I searched my issue and read a great deal, but not enough specific to my needs. I just bought a monster machine: Alienware Aurora 16 with an i9-14900KF processor running 3.20 GHz, 64 gigs DDR5 5600 RAM, and an nVidia 4080 Super (16 gigs RAM) on Windows 11 with a couple M.2 NVMe SSDs. I’m using the most recent Vegas 22 (Build 239) software and I only shoot 1080p. I upgraded from an 8-year-old i7 with a Ti1080 (or something like that) and 16 gigs RAM. Here’s my issue… while the Alienware is CRAZY FAST rendering compared to my old machine, it STILL bogs down on timeline playback when I overlay a single motion title over video! Seriously? A simple Vegas-template motion title over 1080p footage and the preview video spurts and sputters until playback clears that section. My OLD system did that and didn’t cost me $4K! Do all you experience this? Should I have this issue with my powerhouse Alienware? I checked (or unchecked) all the options people told others to do, and my GPU is recognized and enabled. It even does it when I reduce the video preview resolution to draft > quarter! Thoughts? Thanks!

Hello there! Congrats on your new upgrade! Happy to hear render time is better. As for the preview, did you try to enable Dynamic RAM Preview? That makes you manually set how much RAM your computer uses for the previews.

Yes… I learned that from reading through the other wonderful threads. I tried multiple settings with no difference. However, now that I’m thinking about it, I am not sure if I restarted the program, and I definitely did not reboot my computer, before testing.

Did you get your issue resolved? It’s depressing to hear that you’re having issues because I am in the process of building a very similar PC.

I experience this every day and my PC isn’t half bad. (RTX 3060 12GB, 32GB RAM, Intel 11th Gen i7-11700k)
A quick way around this is to select the portion on the timeline you want to preview with a loop region, and pre-render that section by pressing Shift+B.
I’ve tried optimizing Vegas many times, but without success regarding the laggy playback.. If I figure out a way around this in the future I’ll post it in this thread!

I did not. I’ve tried a few things people have recommended, but the only thing that works is the pre-render option.

Thank you; this seems to work OK. It even appears to hold the prerender even when I close the project (not sure if will hold it when I restart my computer). I appreciate your response. I am stymied why my monster of a machine does that for a simple graphic overlay. I was shocked my beast still acts like my 8-year-old machine in this specific area.

And you should be! Total nonsense that your new PC can’t handle simple tasks like this. Definitely depends on Vegas. Performance issues have been around for quite some time now. Really hoped Vegas 22 would have improved in this area as well, but it doesn’t seem like it has gotten any better.

Just to double check, have you enabled GPU Acceleration? ^^
