Hi,
I'd like to report an issue I have been experiencing since early Windows 10 Insider builds (if I remember correctly). At the start of every minute, games stutter for about half a second. The stuttering is literally happening exactly every minute. Sometimes the stutters are barely noticeably and sometimes they are lasting for more than half a second which is extremely distracting.
I found out that the System Resource Usage Monitor (SRUM) of Diagnostics Policy Service is the cause, more specifically the Energy Estimation Provider (eeprov.dll). It seems to collect stats about energy consumption in the background. Stopping the DPS service or just deleting the entry for eeprov.dll at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SRUM\Extensions\{97C2CE28-A37B-4920-B1E9-8B76CD341EC5} fixes the stuttering.
My system:
Windows 10 Pro x64 1511
Packard Bell EasyNote TK 85
Intel Core i5-460M
NVIDIA GeForce GT 540M, using latest display driver 359.00
6 GB DDR3 memory
SSD system drive
I discovered that the stuttering only happens when games are running with the dedicated NVIDIA graphics adapter. The stutters disappear if I switch to the Intel graphics driver. I am not sure who's to blame, SRUM or the NVIDIA driver, but thought I'll report the issue here in any case.
