Acer E11(E3-111) 可以玩 SC2？
1. 可以裝 SC2 HotS： 當然可以！
2. 可以玩： 特效開最低，1 vs 1 小圖勉強可以玩!
只是...部隊 200 vs 200 會戰 frame rate(FPS) 會掉很多，活像是投影片放映。
若，想玩電動（3D）還是買有獨顯的一般筆電比較實在。小筆電就好好當小筆電吧！
粗略評估方式：
=> 2008 年「前」的 3D 遊戲，也許都 OK
=> 2008 年「後」的 3D 遊戲，應該都灌的起來，開最低特效吧！但...不要過份勉強這台小筆電！
=> 純 2D 的遊戲，這台應該是綽綽有餘。

Array size = 2000000, Offset = 0
Total memory required = 45.8 MB.
Each test is run 10 times, but only
the *best* time for each is used.

Your clock granularity/precision appears to be 1 microseconds.
Each test below will take on the order of 9145 microseconds.
(= 9145 clock ticks)
Increase the size of the arrays if this shows that
you are not getting at least 20 clock ticks per test.
