Several Scaler 2 Instances freeze Reaper

My computer is quite powerful, but beginning from 3 Instances of Scaler 2 it gets unusable slow and completely freezes. I use latest Reaper on Windows 10 x64.

Hello,

thanks for reporting, are you using the latest version 2.0.5 ?

Hi Ed,
yes, this happens with the latest version 2.0.5.

It might be important that I use a 4K-Screen.
