在游戏《木卫四协议》里，木卫四协议是虚幻4引擎游戏，所以这个方法可以有效的消除虚幻4引擎游戏的卡顿，玩家记得要清除direct X缓存，把里面的内容全部删除，具体的方法可以看如下。
怎么解决卡顿问题
此方法能有效消除虚幻4引擎游戏的卡顿，包括刚上市的木卫4
记得清除direct X缓存 (删除所有内容) - C:Users(你的用户名)AppDataLocalNVIDIADXCache 或者运行“磁盘清理”勾选"Direct X缓存"
1. 首先使用快捷键Win R调出运行框，复制命令进入如下文件夹
%LOCALAPPDATA蔿listoProtocolSaedConfigWindowsNoEdito
2. 用文本编辑器比如VS Code打开Engine.ini
3. 复制粘贴如下内容，保存 !
