Not even a 1% improvement connecting to West Coast R6S server from East Coast.
In fact, I’m getting spikes of 123ms with Mudfish and 108 without. ???
Same for Black Desert Online and World of Warcraft, all worse ping with MudShark
Please confirm that How to check the basic functionality works fine in your environment. It’s a first thing you should test.
If it works okay. please try to change a mudfish node based on FAQ - Nodes section for your game item. If you’re using the advanced mode, please start with the basic mode.
Yep it works okay. The problem is checking the connection through command prompt with tracert it utilizes the same route Mudfish wants to us, which is already optimal. So what benefits does Mudfish offer me in this case?
If your route is already optimal to reach your game server with your ISP, I don’t think Mudfish can help you to improve your ping more. 
Please ask me for the refund. I can handle it for you.
It’s ok I’ll keep my data. Who knows, maybe someday it’ll be usefuland I’ll be glad I still have traffic balance left to use!
