From 922b038864c6bcc7a2df307a6d37c5563e1eacb3 Mon Sep 17 00:00:00 2001 From: Alex Smith Date: Mon, 5 Jun 2017 15:49:05 +0100 Subject: [PATCH] anv: Set better descriptor set limits Based on discussions with Jason, Ivy Bridge and Bay Trail only actually support 16 samplers, while newer hardware can support more than the current limit of 64. Therefore set the lower limit where needed, and bump up to 128 for everything else. There is also a limit on the total number of other resources of around 250. This allows Dawn of War III to render correctly on ANV.
