Can AMD RX570 into 1080p60fps hardware video encoding?

The SuperTuxKart results at "low settings" seem a bit off compared to version 1.0. Perhaps updating that test would be worth doing.

Using VAAPI hardware encoding in OBS with a RX 570 works just fine at 1080p 30 fps. Going above that to 1080p 60 fps results in 40-50% frames dropped...
