VK_EXT_graphics_pipeline_library is supported, but not recognized by DXVK on Windows

The latest update to AMD drivers in Windows has added the VK_EXT_graphics_pipeline_library extension along with graphicsPipelineLibraryIndependentInterpolationDecoration feature. However, DXVK does not recognize either feature and disable them altogether. This can be observed in all titles, attached vulkaninfo output along with DXVK log.

It is because they disable it when the driver sees dxvk at the moment. It is buggy if used with dxvk.

This is now enabled in the 24.6.1 driver

AMD completely broke Fortnite for me with this driver.

Make a bug report to AMD

Tested and confirmed it's detected correctly today on a multitude of games (NFS U2, NFS MW, NFS MW X360 Stuff Mod, GTA SA, GTA IV) will test a few DX11 games tonight.

If you hit any crash or hang issues then it might be a good idea to try current master (or 2.4 when that lands). The AMD extension implementation revealed a couple of dxvk bugs that have been fixed since 2.3.1.

VK_EXT_graphics_pipeline_library is working on DXVK 2.3.1 for me on my 6900XT on Windows 11 24H2.
However I still get shader stutter in Baldurs Gate 3 DX11 with it. Using dxvk-gplasync is the only way for my setup to eliminate all stuttering in Baldurs Gate 3. Something to consider for others if they have similar stutter situation.

Unfortunately Need for Speed 2015 and Payback crash in the beginning of gameplay on both 2.3.1 and https://github.com/doitsujin/dxvk/actions/runs/9670610157

Can get them to run in windowed mode, but moment you go fullscreen/borderless; they crash.

Yes testing Need for Speed (Windows) on my AMD iGPU it does seem crashy with dxvk. Nvidia gets ingame fine.
