I'd recommend trying a system clean up and a fresh installation of our latest Crimson 16.7.2 drivers, to see if it resolves the performance drop. If the issue persists, then it is probably being caused by something else on your system.
1. Run the Windows self check tool to check scan and automatically repair any corrupt files found in Windows. There is a guide on how to do it here. What you need to do is run an elevated command prompt (elevated means run it as administrator) and type SFC /SCANNOW. This will generate a statement indicating if errors were found the Operating system and if they were fixable.
3. Update Windows. Install all available critical, recommended and optional updates. Often Netframework and Visual C are included in the recommended or optional updates Windows provides. Windows should always be fully up to date before installing our drivers!
4. Use DDU to sweep the system of AMD drivers in safe mode.
5. Install the latest Crimson 16.7.2 drivers once the above is completed and check to see if the issue is resolved.
When I was running my r9 290, after installing these new crimson drivers my fan speed would be set to 30% default for some reason, which would make my card get hot, so you might check that.. Set your fans at about 75-80%.. I ran my target temp at 75c..
Hi pintoi007, I had the same issue for a long time.
I tried many solutions found in various forums on the subject, but none of them solved the problem.
Since the problem was taking place for the second time with another R9 290 video card I decided to check via MSI Afterburner information on the GPU (temperature, activity, fan, etc) I observed that problem started when the temperature was above 75 degrees Celsius. Then I decided to try one last chance ... I bought a watercooler Corsair H55 and a video adapter NZXT Kraken G10. I put the watercooler in my r9 290. Believe it or not this solved the problem in my case.
Today I have 02 PCs, one with a R9 290 and other with a R9 390 and both have watercooler Corsair H55.
I hope this solution works for others as well.
