1。关独显，一劳永逸。（这个方法很傻）
2。认准amd，至少Radeon 独显的笔记本。老amd频率，tdp都不过关，即便驱动完美，照样掉帧。
3。把Linux装入固态硬盘中。你会感受到丝般顺滑，去掉了“卡顿，掉帧”的烦恼。
4。楼主电脑i3-3120m+Radeon 5800，很垃圾的显卡，但玩3d游戏（以team fortress 2举例）仍然30-280帧

Linux, the kernel developed and distributed by Linus Torvalds et al, contains non-Free Software, i.e., software that does not respect your essential freedoms, and it induces you to install additional non-Free Software that it doesn't contain.
GNU Linux-libre is a project to maintain and publish 100% Free kernel forked from Linux, suitable for use in Free System Distributions, removing software that is included without source code, with obfuscated or obscured source code, under non-Free Software licenses, that do not permit you to change the software so that it does what you wish, and that induces or requires you to install additional pieces of non-Free Software.
For example , Linux contains RTL8723BS WiFi driver , realtek HD audio driver and so on
