Bug ID: 110349
Summary: radv: Dragon Quest XI (DXVK) has a graphical glitch
(regression, bisected)
Product: Mesa
Version: git
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Vulkan/radeon
Assignee: mesa-dev@lists.freedesktop.org
Reporter: asheldo...@gmail.com
QA Contact: mesa-dev@lists.freedesktop.org
When running Dragon Quest XI with DXVK, a graphical glitch can be seen. The
glitch tends to flicker in and out from a distance, but once you get closer, it
remains static. I've only tested it at one location, so I can't say if it
appears elsewhere. Here's a screenshot: https://imgur.com/a/v7RnxE9

radv: use typed buffer loads for vertex input fetches
This drastically reduces the number of SGPRs because the driver
now uses descriptors per vertex binding, instead of per vertex
attribute format.
29077 shaders in 15096 tests
Totals:
SGPRS: 1354285 -> 1282109 (-5.33 %)
VGPRS: 909896 -> 908800 (-0.12 %)
Spilled SGPRs: 24840 -> 24811 (-0.12 %)
Code Size: 49221144 -> 48986628 (-0.48 %) bytes
Max Waves: 243930 -> 244229 (0.12 %)
Totals from affected shaders:
SGPRS: 390648 -> 318472 (-18.48 %)
VGPRS: 288432 -> 287336 (-0.38 %)
Spilled SGPRs: 94 -> 65 (-30.85 %)
Code Size: 11548412 -> 11313896 (-2.03 %) bytes
Max Waves: 86460 -> 86759 (0.35 %)
This gives a really tiny boost.

Reverting the commit fixes the glitch. The glitch also doesn't exist when using
AMDVLK.
