I've been using RX570 GPU.
I've found some insert plugins in DAW makes GPU load more than 40%.
When I close visual window of plugins, GPU load goes down to 0% but make it visible, it goes up immediately without any audio processing.
these are plugins with problem :
Izotope Nectar
Izotope RX breath control
Izotope Tonal balance control
Izotope Neutron
Goodhertz plugins
My system info :
Windows10 home 64bit
Ryzen 3600
Asus b450m-a
RX 570
samsung 850 evo
Daw: Cubase 10 , Studio one 4
