Ever since vkd3d 2.4 shadows flicker (also on newer versions), works fine on vkd3d 2.3.1, its very noticeable in open worlds areas where hills cast shadows.

using lutris-GE-Proton7-7-x86_64 with VKD3D_FEATURE_LEVEL 12

logs with trace.

It's a long standing driver bug specific to GCN2 AMD GPUs: https://gitlab.freedesktop.org/mesa/mesa/-/issues/5147
It works fine on other hardware. You can try RADV_DEBUG=nohiz as a workaround.

yeah it looks pretty much buried at this point

well that works, thanks. i also get the performance improvements ever since 2.3.1 which is nice.

@Hadrianneue Hi there. Even if this is a driver issue i just wanted to check if it is still present?

i don't have the gcn2 GPU anymore... issue still open on mesa repo, so its likely still present.
