Currently, the default preset mode is "MAILBOX", which does not respect the current display frame rate and causes performance to reach 100% of a single core. Using "FIFO" (which is the fallback if "MAILBOX" is not available) respects the display frame rate and has no such issues.

CORRECTION: Perhaps it does respect the frame rate, but just does more work in the background between frames even if the only thing being currently drawn is a triangle.
