[1.3 BUG] Native Blitting 1.2 Vs. 1.3 - A 33% drop in performance?

Hi,

Not sure if this is problem on my end…

I wrote a one page demo using SDL 1.2
that just displays a background
and 400 pixels stars and 200 Mario sprites moving

I ported it to SDL 1.3 and it is 30% slower on same machine

SDL 1.2 version ran 60 Frames Per Second (Code::Blocks)
and
SDL 1.3 version runs at 40 FPS (MSVC++ 2008 EE)

This is on my computer with 4 core 2.4 GHz CPU

Again I am not sure if it is problem on my end,
but the code is identical in both demos

Could a 30% drop in native blitting going from 1.2 to 1.3 be possible ?
