i use openwrt with cake sqm and a dscp marking script that i can mark my packets on both upload and download to whatever dscp marking i want.....i also use an app on openwrt call banip to block all the far away servers...ive got all the server ip routes for mw3 data centers...i also use a vpn with these settings that work perfectly...ill use it sometimes to route my traffic to a different location because i live in the caribbean ..my ping is always flat lined...my game runs super smooth after optimizing my network with my openwrt router...you have to prioritize your entire network properly and mark your packets on both the upload and download seperating them into different tins...you need good qos to fine tune and configure your network properly for that ..most qos only mark your upload packets because by the time the game server sends the packets back to your machine its already marked by your isp before it reaches your router..i use a script from openwrt that washes off the isps marking on my download packets and set the markings that i put on my upload packets on to the download..that way my upload and download packets have priority over everything...you need to create a seamless connection to the server making sure your gaming packets dont have to wait in line for your other network traffic both your upload and download...after optimizing my internet properly ive never felt my game run so smooth before
