Bad running game. (Aliens Versus Predator 2)

Wanted to play remember this masterpiece. Downloaded Assembly. Has a resolution of 1366x768. Everything is fine. BUT. In the initial cut scenes flashing white light. Vision another not working (Black screen). With the third mode of vision of a predator, too.In the first mission of the predator lag texture (Stretch across the entire map). Iron normal stalling game of 2015 and earlier at a stable fps. What to do? If you need to find a different version, throw off, I'm too lazy to look :).
