I guess it's not really that surprising, but recording a 4K display eats about one and a half core on Core i5, 2.7 GHz.

Is this with the real Mac RetroClip? That sounds really high, like way higher than expected. Is it an older machine without a hardware video encoder?

Macbook Pro, 13-inch, 2015, Intel graphics 6100. So I guess not. The 4K display is connected via displayport, and runs downscaled at 2560x1440.

OK, I would expect that setup to perform really well (like just a couple % CPU use in activity monitory). If you have a chance, can you send a sample[1] to support at realartists.com? I'd love to see what's taking all that time.
