Sorry for the poor video quality. My phone camera sucks.
Back in the day when I only had this netbook, I had been trolled by its GMA 3600 integrated graphics a lot. The processor was OK but that GMA was just a joke, not only in term of performance but also feature.
Well, I don't get why the frame rate and game performance are much stable when I limit my cores from 4 to 2. The game is not enjoyable when the frame rate strikes. Since Touhou Danmaku games are very sensitive to FPS, I will run into a bullet easily if the FPS is unstable. I don't think this is the problem of Touhou, as I can run it very well on other laptop/PC with multiple cores on it, no crap like this will happen.
Luckily, I have a new PC now, no longer have to play on that trollbook. Now I have Win8 on netbook, strictly for web browsing only, and without that silly GMA 3600 driver installed of course, as Intel states it will not provide any support if you use the driver in OS other than Win7 32-bit. And hey, Win8 is much stable without that GMA driver, seriously, so why find trouble? :)
