Hello everyone,
大家嚎， 

once again, Storm is asking, whether players suffer from a very specific issue. This time, it’s freezes (lags) connected with the first shot in battle (the game “lags” a bit when you shoot) and the destruction of tanks in your visibility range (the game “lags” when the tank dies and the explosion/fire gets rendered). This happened before as well, but Storm states that asks because there are reports of this being especially bad in 9.0 – and I can confirm that, it is worse for me.
Storm又在询问玩家们有没有遇到过一个非常特别的问题。这一次是在每一局第一次开火时的“卡顿”（游戏会在你开火的时候卡一下下）以及在你可视范围中坦克被毁的时候（游戏会在在你的渲染范围中有坦克被摧毁是卡一下） 。这事以前也发生过，但是Storm表示他特意要问的原因是在9.0中反馈这个情况的数量太多了—我个人也能确定这个问题，的确是比以前差。

Storm also asks for Dx Dialog and screenies of your settings, but it’s kinda pointless to post them in comments, he doesn’t come around here.
Storm同时还在向大家索取DX的log文件以及你的设置的截图，但是在评论中发是没啥意义的，因为他不怎么过来。 

From the discussion:
讨论区的内容： 

– there is a myth going around that when you switch to sniper mode, the landscape quality gets redrawn to “maximum quality” in order for you not to shoot into the ground – thus, having lower landscape (terrain) quality than maximum can cause lags. Storm states that this is just urban legend.
有谣言说，你在切换到开镜模式后，景观质量会重新以“最高质量”进行作画，为的是不让你射到地上—因此，选择比最高设置地的地形质量会导致卡顿。Storm表示说这就是都市传说罢了。

– apparently, lags when switching to and from sniper mode (especially often) are caused by re-loading of terrain LOD
在切换开镜与外瞄模式的时候产生的卡顿（经常会出现的卡顿）是由重新读取地形细节级别引起的
