Considering that 60fps is resulting in 30fps, have you tried setting the cap to 120fps?

You don't need to reboot your system for the change to take effect, by the way.
Ah sorry, I meant to say "reboot the game," not my whole system, haha.
I actually typed up a response to your post last night but I guess I didn't submit it -- it was very close to my bedtime so I might have just shut down my PC and gone to bed without realizing I never pressed submit...
Anyway, I did set it to 120 based on the fact that it seemed to only be limiting to about half the desired framerate. It did, in fact, keep things
around 60fps but it wasn't locked and felt and looked kinda of weird. I think it had a huge amount of scattered screen tears everywhere, which maybe explains why it looked like that.
It runs really smooth and responsive with vsync enabled but it does have a huge tear right through the middle of the screen that's extremely obvious, which is why I'm trying to find a solution for it fluctuating between 75-120 (which feels pretty unstable in some cases). I tried to force vsync thru the nVidia control panel as well, it has the same exact effect as the in-game vsync with the huge constant tear. The controls are almost perfectly responsive with vsync off and those high framerates, but there's some scenarios where the fluctuation in framerate is almost 40fps difference and that's when it visually gets kind of uncomfortable for me (tearing starts happening in various parts of the screen simultaneously), though it stays playable, so not finding a solution isn't going to wreck the game experience for me.
Rig is a gaming laptop, and I'm running in OpenGL mode (Vulkan Mode seems like it locks my framerate at exactly 49fps for some reason), Ultra preset with the only change being that I stepped AF up to 16X from 8X preset.

EDIT: well I just tried to play for the first time since booting up after waking up and the vsync problem is completely gone. Changed it to adaptive vsync when I booted on and it's just silky smooth 60fps now, no more tearing. Odd.
