From maybe a week ago, in most games I have usual 40 ping, but then sometimes it goes up to 280 - 288, no idea why. I’m on PC, in EU, never had this issue before and it only happens in ow. My network works ok. I tried reinstall and that didn’t help 
I can hear shoot or abilities and then I can see that shoot/abilities with 1 second delay.

Then you need to write on the Overwatch forums… not here.
