After one day of trying to fix this issue,
My problem Fixed (i do not know what helped 100% but below points are what i did)
-Updated BIOS
-Removed Drivers by DDU and install newest one by Nvidia App
-Increased Virtual Memory(i do not think this helped but some other person also suggested it) (32 GBram increased by 48 GB)
-Automatic Fine tune Clocking from Nvidia app (i also do not think this helped)
-Opened Compability mode and selected windows 8 , always with admin rigths and closed full screen optimization
(Just go to game folder right click on games exe file and do these)
-Always restart pc after making changes
-Did not deleted shader cache files or folders
Only problem i have rightnow is: at every start it took like 3-4 min to loading shaders
My diagnose for this problem is they messed it up on shaders code , other than that game runs pretty smooth at 60fps on High/Ultra
One other thing that annoyed me is, it is alwaays rainy :d
