What will the system requirements be for JK2? Will it be like Elite Force (A P2 233 with 64 Mb RAM and a 8Mb video card minimal) or will it be more?
It's the Q3 engine, so the least thing you need is OpenGL support.
Quite simply, you can't say yet, although I would expect them to be marginally higher than elite force. Not in video card stakes, but a higher processor speed, as the entry level/average machine will have moved up by the time of release.
