Hello, I recently installed Windows 10 over Win 7 and I installed GPU driver 17.12.1 and I also tested 17.12.2.
I noticed a huge CPU spikes when loading a video game map for example, basically when loading level happens. The CPU goes up to 92-98% on bigger map, but usually up to around 72-80% always, even when loading the same level again and again.
This does not happen on Windows 7 with the same driver, I tested it twice. But i can't say for sure if Windows 7 is without this problem, downgrading to Windows 7 and upgrading back again to Windows 10 is pain, but I have not noticed any problems on Windows 7.
And I tested three times on Windows 10 drivers 17.12.1. and 17.11.1. basically these CPU spikes does not happen on driver 17.11.1. (pre-Adrenaline edition).
Yes, the CPU spikes happen even without AMD overlay closed and not started ever.
Also Windows 10 crashes into pure red screen with locked sound sometimes if i try to alt+tab with the overlay opened.
Tested games are Warframe mainly, also Red Orchestra 2 and few others. The CPU goes very high than usual,, then the game stutters after the map is loaded for a few seconds, then the CPU calms itself and goes to normal after loading, takes few seconds, but the stutters can reappear sometime even when in mid-game. (smaller stutters though).
I tested it a lot and I can surely say the 17.11.1 driver does not do that.
I tried to disable every Windows 10 background garbage I could. Nothing fixed it, then tried pre-adrenaline driver and viola, CPU spikes gone.
Can anyone with Windows 10 confirm this?
My PC is:
GPU: AMD R9 280X
CPU: Intel i5-2500
Windows 10 64bit
And yes, I uninstalled the driver with the AMD cleanup utility.
Very bad driver. I will stay with 17.11.1 for now and I hope this will get fixed.
The overlay is buggy as hell too.
Adrenalin drivers seems to have several important bugs, as you can see in other threads..
Please, report to AMD. More people reporting, perhaps they solve the issues soon...
I sent report about crash and bsod in BF1, and crash in Firefox quantum playing Youtube videos.
