The purpose of NetLimiter is to *control selected apps' traffic* in order to allow your "preferred" app to communicate without restrictions. If there are no other application with huge traffic with inhibits your game then NetLimiter can't help you - the problem is (probably) in your network connection itself.
You can’t lower ping with bandwidth. You can have 5 gigabits of bandwidth and still have a high ping. I still need to get dial up up and running to confirm a lot of this. But it’s mainly due to hops your device is taking to connect to the games server. For example, with quake 2, if I ping servers with 3 different networks, home wifi, cellphone 5G, and 4G, I get different pings. 5G and wifi are almost identical, however my 4G network will send me 220 miles opposite of where i want to go and then it connects. Quake 2 showed a 40 millisecond increase from my 48 to 62 range on wifi and 4G. You’d have to learn how to manually control your hops to find the right IP hops to your destination. For another old game I play takes around 13 computers to reach destination. It changes, but your bing is based on distance, not bandwidth. Bandwidth restrictions can prevent tons of problems, especially when a desktop, laptop, or iPad is on all the time. There’s a lot of things to look Into, but bandwidth restrictions is your best bet to prevent a lag spike for a short second even. You migh t want a repeater to connect to for all your devices and run a speed test on at least 2 on the same access point. Manage that and you should almost all lag. However, it depends on your household. Cause 4K videos and social media are much worse on bandwidth than playing a game online. Also, remember there is a difference between mbps and MBps. By default speed tests display megabits per second and not megabytes per second. 8 mbps = 1 MBps. And that’s in binary format and not decimal. Binary it’s 1024 kilobytes to equal a megabyte, in decimal it’s 1000 kilobytes for 1 megabytes. Windows does everything in decimal, while netlimiter does everything in binary. Hope this helps
