Suddenly high CPU usage

Hello,
For a few days I am having trouble with UE4.7.3 and also 4.7.2
The problem is the following: Even without doing anything, the engine uses ca. 40% of my CPU.
When I try to move the camera in the editor window, or even when I browse the Content folders of the project in the engine, the usage goes up to 95%-100%.
What is very strange is, that this happened from one day to the other. Wihtout making any update for UE4.
And it is not bound to a specific project. I also created a new FPS Blueprint project and the same is happening.
It is totally impossible to work with the engine like that.

My PC specifications are:
CPU: Intel i7-3770 with 3.4GHz, 4 cores (8 logical cores)
RAM: 16GB DDR3
GPU: AMD Radeon HD 7970
All partitions of my harddrives have more than 40GB free space.

Has someone an idea what could cause this problem?

Thanks in advance

Well.
I am sorry, my fault. Should check my GPU drivers next time BEFORE posting such a question.
Updating GPU drivers fixed it. Sorry.

Thx for posting your solution :slight_smile:
