From 3a8d6c0880891cf9ccbae8160932bb4cbd2c2ead Mon Sep 17 00:00:00 2001 From: Samuel Pitoiset Date: Mon, 28 Jan 2019 17:41:07 +0100 Subject: [PATCH] radv: re-enable fast depth clears for 16-bit surfaces on VI This has been disabled some months ago because it introduced rendering issues with Shadow Of Warrier II (DXVK). This game is no longer affected, I wonder if 824cfc1ee5e ("radv: rework the TC-compat HTILE hardware bug with COND_EXEC") fixed the problem. I checked The Forest on my Polaris, and it renders fine too. According to Phillip, this gives +5.5% with Rise Of The Tomb Raider and DXVK. This is because DXVK uses 16-bit depth surfaces while the native port from Feral uses 32-bit depth surfaces. Unfortunately, Shadow Of The Tomb Raider isn't affected because it clears each layer of a D16 array texture individually. So it doesn't hit the fast clear path.
