Mobius is a 3D game engine being constructed by William Herrera, which will be used in the Mythic project.
To run Mobius on a laptop, you should have NVIDIA GeForce Go 8200M graphics or other NVIDEA system that supports PhysX.
Mobius utilizes PhysX for physics simulations, which uses recent Nvidea graphics cards for calculations. Mobius also utilizes SDL in order to run under Windows, Linux and Mac.
It's not clear yet the degree to which client/server communication will be separated from Mobius or built into it. In any case, there will be a single executable that will have a command line switch to indicate whether the program runs strictly as a server, strictly as a client, or as both client and server. The client/server mode of operation is convenient for development because developers will be able to test the system on a single computer. It's not possible to run 2 separate instances of Mobius on a single computer, because they will both try to control the graphics card.
