pub fn vsync()👎Deprecated:
busy-waits a fixed 242 HBlanks from the call site instead of syncing to the display; use psx_rt::interrupts::wait_vblank()
Expand description
Wait 242 HBlank periods (~15.4ms) from the moment of the call.
Despite the name, this does NOT sync to the display: reconfiguring
Timer 1 resets its counter, so the wait starts from zero at the call
site. Frame time becomes work + 15.4ms instead of snapping to the
next VBlank – nearly right for light frames, badly slow for heavy
ones. It cannot be repaired here: syncing needs the VBlank IRQ, which
the runtime owns.
