I recently bought a Radeon RX 460 4 GB for my computer. The problem I'm having is that while some games run way faster than before (Steam games), non steam games such as league and overwatch lags to the point where they are unplayable. After quitting those games, it usually makes my computer lag to the point where I can't even do basic internet surfing. .
I've uninstalled and reinstalled drivers multiple times, I am sure the drivers are updated to the most recent. I've uninstalled past drivers. I feel like I've tried everything. I thought adding those games to the Radeon Settings would help, but they did not help at all.
My CPU is an intel i5 4690k, and I have 16 GB ram. The specs should be sufficient enough to play League of Legends or Overwatch, as my past card (GTX 650) ran them very smoothly.
