Not sure whats happening but lately I noticed my performance from my RX480 is subpar., its an MSI RX480 Gaming X 4GB model. It is overclocked at 1340Mhz Core Frequency and 2000 Mhz Memory Clock, however I see the same results when it is not overclocked at default factory settings. Any clues? I have the latest drivers (Crimson 16.11.4).
