I've got an i7-6700 and was switching my cameras to H.265 after I saw the update that now supports hardware acceleration.

After the first camera was changed, cpu spiked to 80-95% from the normal 15-20%. HA is set to Intel in Blue Iris. Changed cam back to H.264h but cpu is still maxing out. Tried a cpu reboot but same thing.

Any ideas? All was working fine. I went back and verified cam is set to h264.
 
After sitting a while, cpu has returned to 15-20% on h.264.

I guess my question is why is it maxing out on h.265. Could it be an Intel driver issue?
 
I'm showing as having the newest driver installed, 26.20.100.7263. Would rolling back and re installing this driver possibly do anything?
 
I guess I'm part of that group. I've followed all of the cpu utilization wiki and my cpu usage occasionally spikes to 90+% but eventually goes back down to 30-40%.
Is there a difference in setting cameras to H.264H vs H.264 in regard to Intel Decoding. I've been using H.264H in my cams that have it.
 
Long time lurker. First time poster.

I recently upgraded my cameras and put Blue Iris on a new machine.

System:
i5-6600 - 8gb - 240GB SSD for DB and OS - Two 3tb older hard drives with recordings spread across them for on old Freenas box.
Cameras:
5 - 8mp (1 camera running in night mode due to the light from the garage door when it is open. Black and white allows it to work much better. )
1 - 2mp

Followed the Blue Iris setup guide using Direct to Disk, 15 fps etc.

I am doing continuous recording with alerts and using Sentry.

In my testing H.264 and H.265 had the same usage. H.265+ had a significant impact to CPU usage.

My ~ results:
H.264 : CPU 30 - 40% GPU - 30%
H.265 : CPU 30 - 40% GPU - 30%
H.265+: CPU 60 - 80% GPU - 30%

I plan to add an additional 2 - 5mp cameras and feel like I will have plenty of CPU to handle the additional 2 cameras.
