I used my r9 380x for almost 6 months now without any errors etc. I downloaded the latest driver from AMD software and it started messing up my system. I was getting constant black screens and BSOD. Also, I tried user benchmark and my gpu ran the tests at only 10-15fps (down from 90-100fps before the update). I somehow managed to rollback the driver and black screens have managed to stop but the lag remains the same. Also, I downloaded MSI afterburner and it shows that my core clock is at 300MHz. Please help
