一、服务器配置

对于所有服务器来说，配置越高，价格也就越高。比如一台普通独立游戏服务器配置的价格月付在1000元人民币以内，中等配置的价格月付在1000到5000块钱之间，高端配置的价格月付一般在万元以上。不同配置的价格相差很大，其性能相差也很大。因此，大家要合理的进行选择，选择适合自己的即可。

二、服务器带宽

对于游戏服务器来说，带宽是器最重要的一个因素。带宽的大小与质量的高低均是影响游戏服务器的重要原因。百兆共享带宽与百兆独享带宽的价格相差非常大，至于具体的价格也都不太一样，当然，也跟机房有一定的关系。

三、安全防御性能

对于游戏服务器来说，一般都很容易受到黑客的攻击，特别是对于一些热门网络游戏。所以，选择一家能提供高防服务器的IDC商尤为重要。对于游戏服务器来说，防御能力越强，其价格也就越高。

逃离塔科夫有七个俄区服务器。
七个服务器分别是叶卡特琳堡、阿斯塔纳、莫斯科1、莫斯科2、圣彼得堡、莫斯科3、哈巴洛夫斯克。在俄区服务器前面都有三个字母RUS，你只要点击任意带有RUS的服务器就能进俄区玩儿了。
值得一提的是，因为逃离塔科夫是俄罗斯游戏，所有俄区玩家比较多，服务器也会比较卡。其中哈巴洛夫斯克的延迟更是接近500左右。所有进俄区之前一定要开加速，以尽量避免卡顿。
