From 5c1233ed620754c1691ffc6fc68d3f58f29a8d03 Mon Sep 17 00:00:00 2001 From: Samuel Pitoiset Date: Thu, 19 Apr 2018 13:48:33 +0200 Subject: [PATCH] radv: use a global BO list only for VK_EXT_descriptor_indexing Maintaining two different paths is annoying but this gets rid of the performance regression introduced by the global BO list. We might find a better solution in the future, but for now just keeps two paths.
