The Quick Sync Video Memory Leak
Some versions of the Intel Graphics Driver cause a memory leak when Hardware Acceleration is used in Blue Iris. On systems with this problem, memory usage, CPU usage, or both will climb continuously, typically reaching their limit within a few hours.
To exacerbate this problem, Windows 10 often "upgrades" your Intel Graphics Driver in the background, causing this problem to reappear spontaneously after you thought you fixed it. On Windows 10 Professional, you can disable driver updates for specific hardware by following this procedure
The solution is to install an Intel Graphics Driver version that does not suffer from the memory leak problem. Different CPU generations require different drivers.

Disable Windows 10's Automatic Driver Updates
It is often necessary to prevent Windows 10 from automatically updating the graphics driver, or else it can reinstall a bad version again.
This can be done via the setting "Prevent installation of devices that match these device IDs
" in the group policy editor in Windows (Pro editions). Here is the full procedure: <Disable Windows 10's Automatic Driver Updates
