Compared to yesterdays 42 regressions nosb versus sb it's now down to
five regressions within -t tessellation:
executionÂ
1in-1outÂ
tes-input/tes-input-gl_clipdistance
tes-input/tes-input-patch-mat2x4_2
tes-input/tes-input-patch-mat3x4_2
tes-input/tes-input-patch-mat4
and one failure became a crash in
trivial-tess-gs_no-gs-inputs
but the crash can easily be alleviated with a patch I send out later.
(I tried to send it yesterday, but noted today that something had gone
wrong, i.e. I did send an empty email instead).
Some numbers on 6870HD:
Heaven 1280x1024
Quality: High, Tesselation: Normal, Anti-Aliasing: Off
FPS: 18.5 [5.7, 70] (was: 12.6 [4.0, 61] before any optimization).
Tessmark x32, 1024x640
FPS: 45, 2153 points (was 10, 635)

I'll check this out.
Many thanks for your work on this,
Gert
