Big performance drop on Vulkan after massive glibc update

I couldn't detect which packages are responsible for it, but Shadow of The Tomb Raider (Vulkan) has suffered 16% perform drop after glibc massive update (between January and February) in current. It seems like a CPU bottleneck, according to the benchmark.

I have GTX 1650 Super, and both kernel and Nvidia drivers (460.56) are still the same.

Funny enough, OpenGL performance hasn't changed at all.
