方法：
1、steam启动项
右键你的游戏点击设置启动项，输入如下字符：-malloc=system +mat_antialias 0 window -USEALLAVAILABLECORES -sm4，最后点击确定。
2、文件设置
开始，运行，然后输入%appdata%，或者直接打开计算机打开C盘-用户-用户名文件夹-AppData-Roaming，进入相应的文件夹位置，然后逐一点开local-ShooterGame或者TSLGame-Saved-Config-WindowNoEditor，在这个文件夹中打开GameUserSettings.ini文件。

sg.ViewDistanceQuality=0
sg.AntiAliasingQuality=0
sg.ShadowQuality=0
sg.PostProcessQuality=0
sg.TextureQuality=0

将上面的这段话复制到GameUserSettings.ini最下面然后保存。
