Description

I have been using my Windows 11 PC with Retroarch and AMD RX560 for some time without having any problems with the VULKAN drivers.
I have constantly updated both the drivers for AMD and Retroarch, today we find ourselves with version 1.17 of Retroarch, the AMD Adrenaline drivers 24.1.1. Unfortunately, I have already been forced to use the GLCORE video drivers for several versions since if I put the VULKAN video drivers I get constant and annoying stuttering.
At this point, to understand if the problem depended on retroarch or the AMD drivers, I downloaded the retroarch version 1.13 from Buildbot. I used the same Mame core and the same romset (0.197) and with the old retroarch version 1.13, I don't have any stuttering problem with the Vulkan drivers, so this problem is present in version 1.17, 1.16 and maybe even some other older versions , but with version 1.13 everything works perfectly.
Can this problem be solved?

Research direction

Reproduce the stuttering on Windows 11 with an AMD RX560, RetroArch 1.17, the Vulkan video driver, the MAME core, and ROM set 0.197, then compare it with RetroArch 1.13 using the same setup. Trace the regression between those versions and verify that Vulkan playback no longer stutters while GLCORE remains a comparison point.
