Slower VEGAS performance after upgrading GPU?

Hi everyone,

I recently upgraded my graphics card to a Gigabyte GeForce RTX 5070 WINDFORCE OC, and since then I've noticed that VEGAS Pro feels slower, especially when working on the timeline or previewing heavy projects. Previously, I was using an RTX 3070, and the performance was noticeably smoother.

I've already updated to the latest NVIDIA drivers and made sure the new GPU is selected in both the NVIDIA Control Panel and within VEGAS settings. I've also cleared the cache and adjusted the preview quality settings, but overall performance still feels a bit laggy.

Has anyone else experienced something similar after switching to a new GPU?
Are there any additional tweaks I should check—maybe in VEGAS, the BIOS, or Windows?

I'd really appreciate any advice or shared experiences.
Thanks in advance!

What I did before I upgraded my GPU, I did some rendering tests with my projects. That told me all I needed to know.

Feel free to try the benchmarks in my signature and we can see if it's performing as expected.

Do you notice issues with certain media?

Thank you both for the replies!

To clarify a bit more: what I'm noticing is mostly during timeline navigation, especially when using my Shuttle Pro v2 controller. When I move frame by frame, there's a noticeable delay or sluggishness—sometimes VEGAS even takes a moment to respond. It doesn't feel as fluid as before.

Just the day before upgrading the GPU (from RTX 3070 to RTX 5070), this wasn't an issue at all. Everything felt much snappier with the older card, especially when scrubbing through the timeline or moving frame-by-frame.

Ironically, I might even say that renders feel slightly faster now, but the overall usability and responsiveness of VEGAS have definitely taken a hit.

Any ideas what could be causing this? Could it be something related to drivers, BIOS, or how VEGAS interacts with this newer GPU?

Also, thank you RogerS for the benchmark suggestion — I’ll definitely try it. Unfortunately, I’m currently short on time due to work, but I’ll make sure to run the tests sometime next week.

Thanks again!
