And this from GB member GamingPhreak who tried it.
It uses whatever Windows desktop resolution you are using, which for most people nowadays is 1920x1080. That's a big improvement since the original game runs at 640x480 only. Other than resolution, character models look much smoother than the blocky ones in the original game. Background graphics and cut scenes are also more detailed, but to a lesser extent since upscaling them doesn't work as well on them. But the biggest improvement is that the game is now less prone to crashes and other compatibility issues on modern PCs.
