Is it any commits around that date that COULD have done something to some effects like that? If you have a particular commit in mind, i could do a git revert to that and rebuild vkd3d to test perhaps?
You could try with VKD3D_DISABLE_EXTENSIONS=VK_EXT_descriptor_indexing. I don't expect any other recent commit could affect performance.
