Same here, 7800x3d. Season 29 is a micro stuttering mess and a huge lag on my squad wipe. CPU, GPU and LAN tweaking got me ZERO results and why would it, Season 28 was fine and now "the fix" fixed it all right.
Are you on Steam or EA app by the way?
Same here on 9700x, only at intervals it happens, had no problems in S28. EAapp. RX 9060XT 16Gb.
i notice it best when running , the weapon animation or legend will stutter a bit at times.
Its not your CPU ... its the game, or servers (which are worse again since S29, for me at least in Central Europe). They did some update with the lighting in S29, most people also have less FPS
