@sheila5 if you use GPU for rendering it always lags, because GPU always render with 100% and her are no resources left for the display. You also can open 2 instances of sheep it to render with CPU and GPU at the same time. In this case you need to reduce the CPU cores at least at 2 because the CPU have to put the data to the GPU. So you can pause the instance from GPU sheepit if you want to work and have more control.
