I'm not super technical, but I found what I think is a pretty massive clue to the issue, at least for me.
I use OBS Studio to capture what is happening on my screen in a video. Frustratingly, I've never been able to capture the game going from regular to laggy. Yesterday, the lag occurred while I wasn't recording. I figured that I'd capture the lagginess via OBS anyhow just to provide something to the developers. As soon as I opened OBS, the problem resolved itself. Note, this is the first time I've seen the problem resolve without restarting my computer.
I've had an ongoing thread with ChatGPT about this issue and added this piece of information. The fact that opening OBS studio fixed it, and the fact I've never been able to capture it while recording via OBS studio may not be a coincidence.
Chat GPT thinks it's possible that OBS Studio may fix the issue:
When OBS launches, it:
Initializes your GPU (NVENC encoder on your GTX 1660 Super)
Engages hardware acceleration
Changes how GPU resources are prioritized
What this can fix:
GPU driver hiccups
Stuck render queues
UI lag where the mouse is smooth but clicks are delayed (very telling symptom)
Note that this would also mean that the issue is not memory bleed, but rather something else:
With Out of the Park Baseball 27, youre not dealing with a GPU-heavy gameits more CPU/UI-driven.
That means your issue is likely:
UI thread blocking
Event queue delay
Something getting stuck in the app or OS
OBS kicking in could:
Change timing just enough to clear the backlog
🧩 5. Background process conflict
Another possibility:
A background app (overlay, driver service, etc.) is causing contention
OBS opening changes resource usage → conflict disappears
Common culprits:
NVIDIA overlays
Game bar
Input software
Browser hardware acceleration
It also recommended some debugging steps, but I have not tried any of them yet. See bottom of this conversation:

I'd be interested to find out if anyone else can snap their laggy computer out of it by activating OBS Studio. If so, it could be an important clue to the root cause of the issue. It's a free app if you don't have it.
