This happened while playing Apex Legends and killed my night.
Game settings are on max, and my PC was capable of running game well when I started playing it 2 months ago - 100fps(constant)@1440p. It started with fps spikes from 120fps down to 60 with clear tearing - roughly every half hour. I checked temps and everything was sub 75c.
I tried the driver updates in Radeon Settings, hoping it would solve the problem, but instead after updating to 19.5.2, things got worse. Apex Legends is crashing soon after Radeon Settings crashes (tried to end task and then refresh it, but it did not work.
Radeon Settings will not function properly - I can't stream, record, or even open the overlay in games.
