I want to lower the CPU usage and started the Performance Analysis in Visual Studio on both versions. After this, I compared both reports and it did show the following top 5 (Exclusive Samples):

I have no idea what this DWrite.dll means and what its function is.. The only thing I saw from the Function Details was the following:
