@mpkupriyanov I think it's because there too many SKCropNode and cause offscreen buffer.

according to the AppleDoc:

Use crop nodes sparingly. Because they require an additional offscreen memory buffer to perform the crop and add a rendering operation into the offscreen buffer, they add notably more overhead to the app.

Thanks a lot, Hanson!
It is works a little better, but overhead is still huge!
