I used blue iris 4 for a few weeks anticipating version 5. It worked fine on a 7th gen i3 laptop 8gb ddr4 256ssd for one generic eBay IP PTZ. Iris 5 keeps the CPU at 75% vs 20 with the previous version. I have 64bit OS, what am I missing or what settings need to change to keep it from using all of the resources then crash? Thanks for your time.

I'm running BI5 on Win10 on a slightly more powerful computer, but haven't seen a difference in CPU usage. Do you get any errors when it crashes?

Do you get any error messages when it crashes?
