Heroes of Might and Magic V [Game Discussion]

Hello. I felt nostalgic and installed Heroes 5 Gold, but I immediately encountered a familiar problem that I couldn't solve a couple of years ago, and I gave up: in the in-game cutscenes, the movement of trees has about 5 FPS, and the circle under the hero on the map also has such a low FPS, which prevents me from enjoying the game. Everything else seems to work normally, except that in TotE, the menu battle with the cyclops is displayed incorrectly, but that's a minor issue.
I tried various compatibility settings in the properties, and other solutions found online, but nothing helped.
Maybe someone here knows something, thanks.
