After installing Windows XP Professional on my Asus Eee PC 900, I could finally play some games!

Isn’t it amazing, that all these games, requiring quite good computers, run on a laptop with really spare hardware?

Processor: Intel(R) Celeron(R) M processor 900MHz
Memory: 1 GB DDR2-400 DDR2 SDRAM
Graphics: Mobile Intel(R) 915GM/GMS,910GML Express Chipset 64 MB
Hard Disc: ASUS-PHISON OB SSD, 4GB + 16GB

That so many games are running is due to the fact, that the Asus hardware isn’t as weak as it seems. Normal game requirements are optimized for a Intel Pentium 4 processor, but the Celeron is a lot more powerful, so even games requiring 1.2 GHz on a P4 can run on a 900 MHz Celeron.
Then the graphics card is also quite good, just the texture memory with 64MB is a little bit short. The supported vertex and pixel shaders (V 2.0) are enough for many games, and the 4 pixel pipelines with a 300 MHz processing unit can render a lot.

See proof in the videos below (Here a playlist with all the videos on YouTube).

Garry’s Mod 9 (Half Life 2 mod):

To get it running smoothly, you should add a parameter in the launch options to use only DirectX 7.0 support: “-dxlevel 70″
Switch the resolution to 800×600, and all the other things to low. The graphics will still look quite nice, and it runs fine!
