Hi, I’m using this for Blade and Soul and my ms is improved a lot but for some reason my fps drops from 60 to 10 when using.
Frankly speaking I don’t know. I think normally FPS is related with your graphic card performance. Did you compare FPS value with or without Mudfish? And please check how much resources are used by Mudfish processes.
I think you encountered CDN and Mudfish issue. 
I’d reset your mudfish credits.
