TN value is too high when playing games on official servers

Hlello my friend, i have this some problem, my TN sometimes hit 500-1k, small maps hit less then 100, to adjust this problem and solve like 80-90%, i set this configs on my laptop MSI, graphic game all low, disable gsync, enable dlss balanced, resolution scale btw 100-150 and the main solver the problem are set fps to 40-45, in my case solve at 35, enter painel nvdia "if you have a nvdia", low latency mode-ultra/high, power-management-mode max performance, motion-blur, film-grain, chromatic-aberration all disable, on windows energy mode:max, on networking try to use 5g. i was reading something about bf6 dont work well at ipv6, check it, i change it to ipv4 in my case i disable lock overcloking at my bios and for battery i set max performance!! But FPS to 45-35 was the main adjust to solve this HIGH tn, now my TN keep safe btf 4-10 small maps and conquest mode, sometimes when have a lot of players around, tanks, explosions and etcs, git 200-max-400, but just sometimes

obs: turn off all others app, discord etcs, only bf6 and you
