not sure, because, ok I explain:
I were gonna do the Jazz FPS with Gamemaker 5.3 with one engine, but now the engine is corrupting my textures in exe and I have either get new gfx card and Gamemaker 6.0 because it can do easily 3D games or use the old one but first ask help from the maker of that engine.. but I prefer buying new gfx card because it is also useful in other cases, too
