Intermittent drop in FPS?

Hello again friends!

Got a weird one. We have a new install, and so far everything is running lovely and smooth. I'll start with the setup.

Win 11
Intel Core Ultra 7 265KF
64GB ram
Blackmagic Decklink pro 8k g2

2x projectors running via SDI out on BM card
1x HDMI in via BM card.

Runs absolutely smooth as a butter at 60fps 4k 2160p50 but after a few hours FPS starts to drop and changing clips becomes stuttery. This seems to clear on application restart, but I'd like to not, obviously.

Clips are 30fps, and between 1gb and 8gb in size. Minimal effects etc.

Aside from lowering the FPS of the output and project, is there anything else I could do to troubleshoot?

Feel free to tell me to go away, I'm just in awe of how helpful the folks have been here so far.

Do you see any consistent climb in RAM, or VRAM usage?

How many are the "few hours"?
