专门研究了一下，似乎输入延迟这个东西很有讲究。延迟大了对于游戏很有危害。


老外用专业硬件和软件测试的延迟，不同的机种数值相差挺大的（2013年数据）：

User Reviewed HDTV's:

An area for user reviews of HDTV's that don't have hard results, however according to the poster "feels" to have low input lag. This section was added due to the very limited number of HDTV reviews that actually test for input lag. So, these HDTV's listed might be worth trying out at a store for yourself.

各个游戏机种的输入延迟

街霸33硬核专题之各平台输入延迟对比

输入延迟对于核心33玩家来说是个关乎生死的因素。为了探究各个平台以及模拟器版本的输入延迟，升龙拳论坛玩家iostopz对各个平台进行了对比。以下是他的测试环境：

1. 通过改装摇杆，实现在按下HK键时，会有一个LED灯亮起。

2. 架设一个120fps刷新率的摄像机，来同时录制摇杆（LED）和视频屏幕。在回放时，逐帧播放视频，从LED亮起开始算起，到人物发起动作截止，计算之间的帧数差。

3. 主机和街机平台用的是CRT显示器。模拟器平台用的是Win 7和LCD屏幕 (Dell U2312HM)

4. 在各个平台上录制春丽的HK 50次，最后平均出输入延迟 （从按下HK键，到屏幕上角色开始动作所需帧数）

以下是测试结果（单位是帧）：

街机和各主机版本测试 – Spreadsheet （原始数据连接）
CPS3 – 3.6  （这个是街机）
PS2 – 4.7
PS3 (高清滤镜开启) – 3.8
PS3 (高清滤镜关闭) – 3.8
360 (高清滤镜关闭) – 4.1
360 (训练模式) – 3.9
Dreamcast – 6.

模拟器测试（不包含LCD显示延迟）
FBA (windows aero 效果开启) – 6.0
FBA (windows aero 效果关闭) – 4.6
Shmupmame (windows aero 效果开启) – 5.4
Shmupmame (windowsaero 效果开启) – 3.8
Shmupmame (全屏游戏 aero 效果关闭) – 3.7

模拟器测试（包含LCD显示延迟）
FBA (aero 效果开启) – 6.5
FBA (aero 效果关闭) – 5.1
Shmupmame (aero 效果开启) – 6.0
Shmupmame (aero 效果关闭) – 4.4
Shmupmame (全屏游戏 aero 效果关闭) – 4.3
*所有结果的误差值为正负0.5帧

通过这个结果说明，如果你不是土豪买不起街机的话，那么用PS3连接CRT显示器才能还原最接近街机的手感。
