<span class="quote">> On SKL GT2, the regressions are following:
> - 10% GfxBench Tessellation (onscreen & offscreen)
> - 5% SynMark2 GSCloth
> - 2-3% GpuTest Julia FP64
> - 1-2% Unigine Heaven (high quality with tessellation, no AA)
> - 1% GfxBench ALU2 (onscreen & offscreen), SynMark PSPom</span >

<span class="quote">> This is fixed by the following commit now in master:</span >
...
<span class="quote">> intel/nir: Vectorize all IO</span >
All the other tests improved by the amount regressed, except for these two
which were not affected by the fix:
- GpuTest Julia FP64
- SynMark PSPom
I assume PSPom drop was fixed already in October, with the "nir: Copy
propagation between blocks" commit (but it regressed last month, I'll file
separate bug for that). FP64 case isn't really relevant.
VERIFIED.</pre>
