    I have the specs: AMD Ryzen 5 5500, NVIDIA GeForce RTX 4060, 16Gb RAM 2667 mhz

    First of all, sorry for joining the discussion late. But Merry Christmas to everyone.

    I read through it and, as I'm quite a novice when it comes to hardware, I'd like confirmation that I understood correctly.
    Do I have to set the RAM to 3200MHz and the FCLK to 1600MHz, and then my problems with BF6 would be solved?


  • 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

    no, in your case, go to your BIOS and just set FCLK to 1333 MHz (half of 2667). also enable DOCP if it's disabled.

    it's possible that this won't solve your issue straight away. in my case, and some others' from what i've seen, it only mitigated it. IF you still get TN, even if it's less than before, try capping your framerate in-game (the lower the better, requires using fullscreen and disabling V-Sync)
