I've found a widescreen fix that lets me play the game. https://github.com/ThirteenAG/WidescreenFixesPack/releases/tag/gta3
Can I use it during runs or is it prohibited?
Thanks for the response, I've had widescreen off but couldnt play game without a fix but with DXWnd after few painful battles with the program I've managed to get it to work. Thanks for the fast response <3
