I got ya bro - For me the issue is also very annoying. But what I cant undersand is why more than 2 years later the issue still persists...
As of today the issue still persists. On the battlemap the dynamic shadows are flickering - at least on my system: I12900k, 3080ti, 32GB DDR5
Are there any updates on this yet? Today I started the game and there were those flickering shadows on the battle map again...
