From a071425817f8ea79336c08f0c4bf1576e0726b68 Mon Sep 17 00:00:00 2001 From: Ville Syrjälä Date: Tue, 8 Jul 2014 15:34:27 +0300 Subject: i915: Override mip filter to nearest with aniso MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit gen2 doesn't supporte linear mip filter with anisotropic min/mag filtering. The hardware would automagically downgrade the min/mag filters to linear in such cases, which IMO looks worse than forcing the mip filter to nearest.
