I concur with guillaume on this.
Had similar experience with the rasterizer in 5.0.x
Shadows aliasing pb even with insane settings.

How do you deal with shadows sampling and texture sampling ? I can't find a
way to remove aliasing problem when I use rasterized mode.
If I use a big collect rate the problem is still there and the render time
are huge. I must use the default scanline on some shots where rapid motion
did the job far better in the past with 4.2 ( a lot of geometry ). Since mr
3.4/rasterizer mode, even geometry details are faster to render in normal
mode.. I use something like 1-3 with a threshold of 0.001, and the render
farm is so happy !
Cheers
