Hello everyone,
大家嚎， 

9.0 issue post spam continues – this time, Storm posts about triple buffering. He states that the theory about positive effects (less microlags and more FPS on average and weak computers) of disabling the triple buffering in WoT was confirmed, but this ONLY works if Vsync is disabled as well.
9.0问题刷屏贴再开—这次，Storm发的是关于三倍缓冲的。他表示说关于在WOT中关闭三倍缓冲对游戏的表现有正面效果（卡顿更少，平均帧数更高，老爷机什么）这个理论被证明有效，但是这仅仅在垂直同步也被关掉的情况下才会生效。

In order to do that, you have to edit the file “preferences.xml” (usually in this folder: c:\Users\___username___\AppData\Roaming\wargaming.net\WorldOfTanks\) by setting its value to “false” like this:
想要这么做的话，你需要编辑“preferences.xml”（通常路径为：c:\Users(用户)\当前用户名\AppData\Roaming\wargaming.net\WorldOfTanks\） ，把它的值设为False。像这样：

Once again, in order for this to work, Storm emphasizes that Vsync (vertical synchronization) needs to be turned off. With it turned on, it’s better to leave it as it is. He adds that 9.0 has a TON of issues.
再说一次，为了让这个机制正常工作，Storm强调说垂直同步一定要关掉。如果垂直同步是开的话，那就别改了。他补充说9.0有特别多的问题。 

From the discussion:
讨论区的内容： 

– this setting was supposed to be turned off by default, but someone at WG screwed it up
这个设定默认应该是关闭的，但是WG有人好像玩脱了

– this will NOT be fixed by the Friday hotfix (SS: this bug was discovered today, while the micropatch is ready for download since yesterday or so), it’s possible however that this will be changed by another micropatch
这个在周五推送的hotfix中不会被修复（SS：这个Bug是今天才发现的，而hotfix好像是昨天就开放下载了的样子），然而这个bug有可能会通过另一个hotfix再次进行修复。
