So I've had my Radeon RX 460 for the past 2 months and have been loving it. But recently today I have been noticing that my Overwatch has gone from 60 FPS to 5 FPS, without maxing CPU! So I booted up MSI Afterburner to see what the issue was and even when idling the GPU Usage was spiking up to 100%! I don't know why this is happening and haven't seen any issues before the new driver update (which I doubt has any issue at all). Below are my specs and help ASAP is appreciated!
OS: Desktop with Windows 10 64 Bit
GPU: Radeon RX 460 4GB GDDR5 (GV-RX460WF2OC-4GD)
CPU: AMD FX-4300
RAM: 8GB DDR3
PSU: Corsair RM750x
Monitor: Some HP Monitor
