Trying several WINEDEBUG options I found these wined3d error:
15982.773:01ec:warn:d3d_perf:texture_resource_sub_resource_map Mapping a dynamic texture without WINED3D_MAP_DISCARD. 15982.773:01ec:warn:d3d:wined3d_context_gl_bind_shader_resources No resource view bound at index 0, X.
With the last of two repeated for 7 times with various X values.
The reference to "d3d_perf", also looking the comments for spawning lines in the code, would seem quite clearly the cause of the performance degradation.
