I tried to use a few synths from Arturia in Demo mode. When I adding them to the VST track, interface of the Cubase and all VSTS is starting to lag (micro freezes 1-3 seconds). Audio works well. Any tips on why it happens and how to solve it? I already tried to reinstall and update graphic drivers.
I’m on Win 10, NVIDIA GTX 970. 16 GB RAM, Intel i7-4770k, etc.
