Give us a DXDiag please. 

Use CPU-z and post us some screenshots of Motherboard, Memory, SPD. 

Other stuff: 

I have problems using freesync it is not smooth i changed my config fr33thys and disabled freesync. 

Since then my game is smooth. 

Out of interest, can u backup your Config file / folder and try the one fr33thy provides?

everything looks very good, not really an idea what to suggest next. 

Usual problems are, single dim ram, not in dual mode, no xmp profile enabled. 

But from what i see that is all as it should be. 

Can you record a bit of gameplay with all network and fps overlays the game offers enabled? 

So that we see CPU,GPU,SIM,mp/s and CTF & maybe Timenudge. 

Did you backup yours and then test the config?

everything looks perfect but the gameplay is unplayable
I tried every single solution I found on youtube or any page I could reach and there is no diff
for sure I tried the config file weeks ago and no diff

maybe it's the mouse input issue thing?

The mouse input issue should be fixed by the latest update. 

But when i read:

"If you are still experiencing mouse input or stuttering issues after patch 1.3.2.0, please share your updated details clearly, including your mouse polling rate, FPS cap, monitor/VRR setup, full PC specs, platform, and whether the behaviour changed after the patch."

This has to be a problem with VRR (freesync or g-sync), mouse polling and fps cap. 

Since it does not hurt i would suggest you try:

Disabling g-sync and freesync stuff on the hardware site in your monitor so it cannot be turned on by game or drivers. 
Using 120hz or 144hz as monitor refreshrate and cap ingame fps to this value. 

it's kinda worse
do you have any idea there is gonna be a fix for the vrr in the next update?
