Hi to everyone!!
As all of you I tried all this time to find the best settings. Here are my settings and something that really improved my game experience!
ABB on @70%
share access enable
qos 10mb down 5 mb upload
traffic priority 3074:3075 30000:45000 and reverse.
Reservation IP on PS4
disable all media share access
manual setup on PS4 for static IP and enter the MTU that I have from ISP, in my case 1492
And final for all of you that you have FTTC internet connection as I have. I set on the modem from my ISP pppoe pass through and then I set on my xr500 that my connection need log in, I set pppoe and I put my username and password from my ISP. With this way you avoid the double NAT.
With the above settings for 2 days now I play and my hit detection is perfect. Never first shoot first die. And I have really the feeling that all gunfights that I loose I fair. I am not a pro player but now I do very good scores and positive KD ratio. I am playing on hardcore mode with MP5 and only need 2 bullets to eliminate the enemy.
