All of this was tested using the Shareware Demo v1.01.
Around 40 frames per second at 800x600. On Linux performance is almost identical, but suffers big slowdowns when there are a lot of simultaneous sound effects.
WINDOWS: If the demo doesn't want to install, just extract the contents with 7zip and then execute the extracted Setup.exe file.
Once the demo is installed, delete the file Video_3DFx.dll. If some error messages appear ("sgl.dll file not found" and stuff) don't worry, just ignore them.
LINUX: Don't delete the Video_3DFx.dll file, instead download this Glide Wrapper and install it. Then the demo should start without any problems.
WINDOWS: Maximum details, 800x600, any 3D Card Adapter.
LINUX: 640x480. Though if you want to play at 800x600 open the "Data/config.ned" file with a text editor and change the following line:
Don't forget to configure the controls using keyboard and mouse, WASD for movement and non-inverted "Y Axis Looking".
How much I played
The whole demo.
The map doesn't show at all:
SHOULD YOU PLAY IT ON A NETBOOK?
Performance is very good (but not that good on Linux).
The most important thing, it's an awesome game.
Classic DOS Games (Download the Shareware v1.01 demo).
