A small (480B - 5.7KB) V8 memory regression occurred in the Chromium commit range of 537682 - 537692. Affected graphs can be seen here https://chromeperf.appspot.com/group_report?keys=agxzfmNocm9tZXBlcmZyFAsSB0Fub21hbHkYgICQvP28ugoM.

There are very few changes in the revision range, and no VR-related changes. However, this doesn't appear to be a general Chrome regression, as no non-VR regressions are listed in the list of performance changes for that revision range.
