From 68116dcd5a05508af06cd41ca14faab1b910a934 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Mon, 2 May 2016 10:24:43 -0600 Subject: [PATCH] cso: null-out previously bound sampler states If, for example, we previously had 2 sampler states bound and now we are binding one, we'd leave the second sampler state unchanged. This change nulls-out the second sampler state in this situation. We're already doing the same thing for sampler views. This silences an occasional warning issued by the VMware driver when the number of sampler views and sampler states disagreed.
