 Issue 609517  has been merged into this issue.

Can investigate a bit - but I wonder how relevant the regression really is - while it is up to a 50% regression, we're talking about going from 300k to 450k of memory - very small numbers.

Most of the concerning regressions for this issue were in the smoothness.top_25_smooth category. These were largely fixed by crrev.com/2028303002. Will likely add an additional change to blacklist the low-end Geforce 320M, which should address the remaining issues.

Merge of blacklist in https://codereview.chromium.org/2066733003/ is approved after pinging with ericrk@.

commit 5033c4f6e97a466f03132ed2cbb655a8807e415c
Author: ericrk <ericrk@chromium.org>

This change blacklists GPU rasterization for all GPUs on MacOS that have not had test coverage.

The GPUs which are not blacklisted are those from the following GPU series:
Intel: 6th and 7th Generation GPUs
NVidia: Geforce 7XX GPUs
NVidia: Geforce 6XX GPUs
ATI: R300 Series GPUs
ATI: R200 Series GPUs
ATI: HD 7XXX series GPUs

This gives us roughly 70% GPU Raster enablement on Mac.

All issues in the original regression have now been regressed either by fixing them, or by blacklisting GPU raster on systems with problematic GPUs.

Nit: chrome://gpu still references this bug, even though it's closed, and referred to a GPU -> GPU regression (where GPU was still much faster than raster). We should probably log a new bug for either widening the whitelist, or explaining why we don't plan to do so, and point chrome://gpu at that.
