Alright so, I normally use the Radeon RX 580 right? Well for some reason after 1 year of using it.. Another GPU appears on my Computer (AMD Radeon RX Vega 11 Graphics). I presume this happened in December or a few days ago after a bought a new monitor. It wasn't on there when i got my PC Originally i believe. My games are noticeably slower. I don't know how to switch from Vega 11 to RX 580. I need help lads.
