Some Windows 11 and 10 users have reported a strange intermittent issue around 4K video playback through Facebook and Youtube. This problem seems to only affect users who have installed the Dragon Suite drivers from their MSI motherboard. In this article, we are going to show you how to fix this annoying problem so you can get back to enjoying those videos lag-free.

What is cFosSpeed?

cFosSpeed is a network driver that is not an MSI product, however, is bundled with MSI software and features in MSI motherboards. The driver attaches itself to existing Internet connections and then optimizes data transfer by using Traffic Shaping (allows maximum speed while ensuring minimal ping).
