We here at www.half-life2.org.uk have made this simple test to help you work out how well your computer will run the Half-Life 2 game, please note that this is unofficial and as accurate as humanly possible. This is not a guarantee that it will work, only an indication of its likelihood. Don't forget the Official Valve benchmark tool will be a much more accurate test of how your computer will run the Half-Life 2 game when its available
pos eso, es para haceros una idea. Si pones que tu targeta tiene 128mb te dice que para jugar a 1024x768 tiene q tener una grafika superior a geforce3 ti, por lo que con geforce 4 mx se podra jugar a 800x600 supongo.

teneis ke daros cuenta de ke el juego adaptara los detalles dependiendo de los FPS ke tengais. esto significa ke si teneis una GF4 MX por ej, dependiendo de como vaya el juego, los detalles subiran y bajaran para ke puedas jugar al juego suavemente. estos cambios seran casi invisibles para nosotros.
