HoMM3 HD bug reports.

Hmm, I have a fast SSD and few folders/saves for testing, and everything runs smoothly, without any freezes. I'll try to optimize the code.

I don't have an SSD. Just a regular HDD. I tried xBRZ, and it's just soooooooo sloooooow. It's hard to describe. I even went into a game and started playing with someone, but in 2 minutes, I bought heroes, upgraded one level, transferred the army to the second hero, and that's basically all I could do.
It's impossible to play with it; what's the point of having it so slow?

In tactical mode. When I attacked someone and immediately selected the right stack to move, the battle dialogue would crash. That is, it was as if I hadn't even attacked yet, but the moves were still spent.
