From b71f91e67270958bdb2940615a83e4d1ccc9ca0a Mon Sep 17 00:00:00 2001 From: Sven Gothel Date: Tue, 25 Mar 2014 06:40:08 +0100 Subject: Bug 801: Elaborate on multisampling performance/quality: Flipquad, RGSS, Quincunx Using poles only as sampling points is not as effective as: flipquad > rgss >> quincunx Best quality would be 'wholeedge', i.e. average every supersample, however performance is worse here.
