Q: What is ExitLag for?
ExitLag is a software developed for players by players that optimizes your connection making it stable, decreasing your ping and freeing you from the feared freezes or spikes. Besides optimizing your connection, ExitLag amplifies the performance of your game increasing the frames per second rate with the FPS Boost tool, giving you the best resources for you to take the lead.
The choice of professional players when the subject is lag removal, improve FPS and generate stability. ExitLag has an innovative multi-path system that allows multiple simultaneous connections to your game servers in different countries
Here is the thing. You have an internet connection. It has x amount of lag. Anything you add to it will increase that lag.
The only time a VPN will help you is if your ISP has some goofy routing scheme from their internet drain and the VPN can provide a better route.
Now, as a user, your not really equipped to determine the best route due ICMP being selectively responded to by core devices (Juniper routers by default will ignore ICMP, which are your PINGs and Traceroutes) so your not really able to figure this out.
If you want to tweak your internet for most game performance, just set up Port Triggering on your router and allow the game on your antivirus and windows firewall. And, if your behind a router or hardware firewall, you can disable the windows one and turn off real time scans on the AV. Just leave the email scan part running.
Your right in that an end user has no influence on how a packet is routed.
Some larger companies can set up a private layer 3 network, running over a mesh layer 2 network and influence routing, but they are in their own cloud.
There are some L3 VPN offerings out there that can allow selective routing, but only through established nodes with the cooperation of the ISPs involved. And this flexibility would not extend to end users as the routing tables would become so large with all the custom routes that any gains from route optimization would be nuetered.
BTW, my day job is designing and implimenting the very networks I described above nationally in the US.
