gt好像是模拟器的选项

其实是核心显卡

核显超频，打开之后下面有频率和电压选项，但是目前我拿平板电脑测试没啥效果，电压暂时不敢乱动。
戴尔论坛里找到的：
I asked Chris M from Dell last year this is his reply
"Although the Aurora-R3 does not use the GT engine, Intel found that if you overclock it along with the CPU you can achieve slightly higher core speeds. We tested this feature with and without CPU overclocking and found it had no impact on stability."
得到的信息 大概就是需要GT引擎，并且和CPU一起超频有潜在效果，并且没有太大稳定性影响。
