Sacado de un foro guiri:
I must say my friend has a Sony Viao, and he has the GMA 945, and it is a piece of CRAP!!!! You can say that it can run CS:Source, but it can only play aim_ or fy_ maps. And if you play any other map, you get like 7 FPS (based on cs_assault, and being inside the building. When we tried to play Dust we got 6, and Aztec we got 2. And he had his res on like 480X600 and all the graphics were low. So i guess the low end games can run fine, but these new games will kill your computer. Just a matter of opinion. link
Asi que yo no diria con tanta rapidez que NO se puede jugar al source con el.
Por ahi leí no se que de DX7, ¿Has probado con Dx8 o 7? Alomejor no soporta dx9 :S:S (No creo).

Ok, I'm gonna probably get a "zomg your laptop sux0rz" response out of this but...
I've been trying to run CS:S on my Vaio VGN-FE550G. The laptop isn't even a year old now (got it in march 06), core duo, integrated intel gma 945/950 video card, gig of ram.
I can manage 56fps with or without tweak, but I'm running -soft and -dxlevel 70 because I get absolutely no display at -8x or -90.
I changed to -gl and got a 1fps boost (woot), but that's only in the video stress test.
Lo mismo que tuvo que hacerlo funcionar en dx7...Asi que prueba eso, jugaras mal y poco, pero poderse, se puede.
