Hej,
Jeg har fået en bærbar (link: http://global.acer.com/products/notebook/as5100.htm).
Grafikkort i den er en ATI Radeon Xpress 1100. Min tidligere bærbar havde et Geforce 4 420 GO som grafikkort og med den kunne jeg spille Counter-Strike Source ok. Det kan jeg så ikke med ATI Radeon Xpress 1100 uden at jeg sætter grafikken væsentligt ned. Dette undrer mig, da den umiddelbart virker hurtigere (de tekniske specs) end grafikkortet i min tidligere bærbar.
Jeg har opdateret til den nyeste driverudgave (ATIs officielle) og mystisk nok mener Steam, at jeg har forældede drivere 
Det skal siges, at jeg har sat grafikken til Highest Quality i Quake III og det er uden dårlige FPS.
