Hi,

The difference is so large that it makes me wonder if ST allocates/resets any rasterizers at all on the fly?

The difference is that ST has just one rasterizer Smile

Quote:

Could the number of rendering threads be pre-selected and a sufficient number of rasterizers be pre-allocated for MT so that there would be no extra allocation/reset -penalty for re-using the same BufferPainter -- as was just introduced by BufferPainter::Create?

Perhaps, but let me try those optimizations I have in mind first...

(Note that while the ST/MT ratio is horrible, it is still <ms for both mt and st... I guess that if you would add that Clear into time, difference would be much less).
