Chrome and Edge stuttering when watching BT sports on a PC
I have been watching BT sport for many years using a PC to stream via Chrome or Edge. In the last month or so both browser have developed problems, the stream keeps stuttering and the event becomes unwatchable. I use Windows 10 (fully up to date with updates), also both browsers are latest versions.
Firefox offers a better watch, no stuttering. So what is different.
I have removed all extensions in Chrome and that made no change to the stuttering. I am on a 200mB download from VM so speed is not an issue, can stream 4K on Netflix with no issues.
Any ideas what can be causing this issue.
