New build GPU behaving strangely.Has spikes while idling.During gaming for example in witcher when enter inventory menu or something simmilar usage drops to 0 or fluctuates but fps stays normal.In addition to that, during the intro scene when you launch witcher I had 30 fps with 0 usage.Same happened in the end of tutorial during that spooky scene.Otherwise FPS is 45-60(average around 52) with all High settings and Nvidia hairworks off.
I downloaded Windows Process Explorer and compared it's GPU usage with MSI afterburner and GPU-Z.Process Explorer doesn't show any spikes but GPU Z and MSI Afterburner do.I have run two UngineValley tests and got normal score for my GPU, prime95 for 1 hour with no issues(I know it's too short but still).
Windows Process Explorer in GPU usage shows crss.exe and dwm.exe
Model is R9 380 2 GB Sapphire Nitro, drivers 15.300.1025.1001, thou MSI afterburner is displaying older drivers.
Picture to compare activity while idling.
