i've been trying some more stuff i read online, and something i found to lower TN even further (removing the issue, in my case) was changing the game to fullscreen and/or capping my frame rate (120 Hz in my case, but i assume the lower, the better). i did this mid-round with the other TN-inducing programs open when i began to see time nudge increase, and it immediately went away.
no guarantees it'll work for you, but i suggest those of you with strong PCs and high-refresh rate monitors try this since it's a very easy change
i was recording, so might as well send proof of this with some screenshots:
this is what the TN graph looked like throughout the matchbefore and after doing the aforementioned changes—went from unstable and high TN with insane spikes like that one, to a stable 14 msand this is how it stayed throughout the rest of the round, even through intense fighting. barely went over ~15 ms outside of some minor spikes, basically noticed nothing
i'm glad it seems like i've found a solution for now. it is annoying having to play on fullscreen and not being able to utilise my hardware to its max, though. i hope they can figure this out and patch the game to make it, idk, behave less strangely. this is the only game i've had this issue with
