Our Vulkan regression test suite includes a Vulkan trace of th=
e Sasha Willems
shadowmapping demo. We found that the fps when playing back that trace file=
 had
 decreased by about 20%. I narrowed down the performance drop to commit
888b7fc.

I duplicated the performance drop with the demo itself. Without commit 888b=
7fc,
the demo runs at an average of 3125 fps. With commit 888b7fc, it runs at 26=
75
fps. This is a performance regression of about 14%. I ran this on a system =
with
an Intel i5-6600K CPU @ 3.50GHz and an AMD Radeon RX470 graphics card.<=
