Quoting things I only heard about, because I don't do enough development in this area, but I recall reading that it impacted performance on pretty much every mobile chip (discounting Apple's because there you go through a completely different API and they got to design the hw together with API).

Among other things, that covers everything running on non-apple, non-nvidia ARM devices, including freshly bought.

...at the cost of creating PSOs at random times which is an expensive operation :/
