BI Using near 100% cpu

Post by aviondubzz »

I have just purchased a dedicated pc just for blueiris and recording. I have only added 3 cameras so far and everything is lagging and it says 99% CPU usage. I believe my pc should be more than capable of handling the tasks.

Gotcha, yeah 3 cameras shouldn't be hitting it that hard. But there are TONS of settings that can make a big difference. Are the cameras set to do Direct to Disk recording?

Also, can you share a screenshot of your BI "Status-> Cameras" tab? The whole thing including the totals at the bottom (you can obscure IPs if you like but they're probably internal addresses that mean nothing).

If you do a Google search for optimize blue iris, there’s a post that suggests setting changes. One I remember had to do with “direct to disc”, deleting overlays in the cameras themselves helps too. There was also something else about encryption. I followed the settings that were recommended and it helped my 3 camera system.

Yup! I believe this https://ipcamtalk.com/wiki/optimizing-b ... cpu-usage/ is the one you're referring to. I've made gains following it as well. Just be sure not to make a post arguing it or contradicting the moderator :lol:

But really, if you have any other questions about any of this, we're here to help. I'm currently at 4 cameras (with one more in a box waiting) with an older CPU - though more cores - but it cruises under 10% CPU almost all the time.

Well op, hopefully you resolved your issue. But in case this is a zombie thread, this is the solution that worked for me.

Solution:
-Limit decoding unless required-OFF on all cameras
-Hardware Acceleration-OFF on all cameras
