i give up to play games on this monster i spent really to much money this computer for gaming but its not stable .
about Monitor i just wait Asus PG27UQ 4K HDR monitor because of that i still using this one

XL2420T 120 Hz BenQ Monitor but 1080p overkill for 1080 ti i understand but why its everytime fps drops , freezings and some shuttering

I update Bios
Last graphich card Drivers With DDU .
i did default witout do any oc when i do this its getting worst.
i change my PSU rm1000i to rm 750x tryed psu and i tryed 2 different ram moduls. 2600 mhz ddr4

I just focus my monitor 1080p maybe doing overkill and bottleneck for my system , but i do not have high resolutaion monitor to try it im still waiting to buy new 1

do you have any idea please advice me , i stuck really ...

I just put bf1 to dx12 just to see. It actually didn't revert back when restarting the game. But then my game was like the OP's video. Stuttering and chopping all over the place. It was terrible.

I should also add to turn gpu memory restriction to off.

In fact you shouldinstall geforce experience to optimize the game for you. then uninstall it if you don't use it.
