Video playback will suffer - there is no hardware acceleration in fbdev.
On the other hand, actually using the hardware video scaling in Intel
has been one excellently reproducible way to hang the GPU on some
people's chips.

Video scaling is the main case where hardware acceleration is faster
than doing it in software.
