So, I decided to play this game after, maybe 10 years of not playing it or more. Got it from moddb, where it was as a free game with free installer and stuff. I installed it and... well, the game itself runs badly. It has some stutters and lags during the gameplay, and video cutscenes lag so much that it is impossible to watch them.
I tried to install that fan made patch that should help to play the game on modern OS without lag and stutters, but after I install that patch, it gives me error that says that, it can't launch because my system does not support Vulkan. And so yeah, I had to re-install the game, install official patches and play with lags, and there is no other way around for me.
But, as I remember, this wasn't the case back in the days in Windows XP era. I played this game last time before this maybe in 2013 or so, when I still had Windows XP, and it worked fine. But now it lags like hell on Windows 10. And sucks that the solution for it works only for those who has modern systems.
