qBittorrent version

qbittorrent 4.1.6

Hardware and Operating System

AMD "Brazos" APU
Windows 7 32bit

What is the problem

qbittorrent 4.1.6 uses much more CPU than 4.1.5, with one single torrent, 24 connections, the whole GUI is barely clickable. In taskmgr it can be observed that QBT 4.1.6 consumes more than 50% percent of CPU on a dual-core computer.

Qbittorrent 4.1.5 does not have this problem and is able to handle >100 connection with ease, CPU usage is around 15%.

Sledge released a build to fix Windows 10 crashing, perhaps it might help here also. Try this build
and report back if you still have CPU performance issues. Cheers.
