The only problem is the 4Story's engine, which doesn't support shaders(or it does, but it is in the very old standart, and the textures and not working correctly with it), This causes all the problems like low perfomance, windows 10 lag problems, and more. Also the game could look much better with working shaders (who knows what shaders are knows why.) Luckily Araz4Story team is currently working very hard on restoring the shaders, and we already have a progress. If this will end up working, we can revive the game.
