FSR 4帧生成曝出Bug：一帧显示四倍时长！120帧像60帧_我的网站

一 |     Villagers in Madhya Pradesh captured a crocodile after suspecting it had swallowed a 10-year-old boy on Monday.,The missing boy, identified as Antar Singh from the village of Raghunathpur, was bathing in the Chambal River in the morning when the alleged incident occurred.,Some villagers claimed to have seen the boy getting dragged into the river and being swallowed by the reptile. They immediately called the boy's family and relatives and managed to catch the crocodile using sticks, rope, and a net.,Hoping the boy might still be alive, the people decided to cut open the crocodile's stomach to save the child.,However, they were stopped by local police and forest officials, who learned about the incident and rushed to the spot, thus preventing the villagers from killing the reptile.,In a video, hundreds of villagers can be seen gathered around the captured crocodile, which is tied with a rope, as they thrust a bamboo between its jaws to prevent it from "chewing the boy.",#MadhyaPradesh: 10-year-old boy swallowed by crocodile while bathing in Chambal river pic.twitter.com/iSzcJtWdWw— Neha Singh (@NehaSingh1912) July 12, 2022,Officials, however, believe that the child may have drowned in the river.

二 |     但这里有一个关键前提，真实帧和生成帧必须均匀交替显示，每帧在屏幕上停留的时间应该大致相同，玩家才会感受到流畅的120fps。如果两帧的显示时长不一致，画面就会出现肉眼可见的卡顿和抖动，帧率数字再高也没有意义。    Hardware Unboxed用慢动作摄像机逐帧拍摄后发现，RX 9070 XT在开启FSR 4帧生成时，真实帧和生成帧的显示时长严重不均，一帧在屏幕上停留的时间大约是相邻帧的四倍。

三 | 这意味着生成帧几乎一闪而过，玩家实际观感更接近60fps而不是120fps。    测试覆盖了多款游戏，没有一款能做到均匀的帧节奏，其中《战神：诸神黄昏》《赛博朋克2077》《四海兄弟：故乡》《刺客信条：黑旗重制版》《生化危机安魂曲》《心灵杀手2》和《红色沙漠》表现最差，《无主之地4》和《乐高蝙蝠侠：黑暗骑士遗产》情况稍好但问题依然存在。    开启垂直同步也无法解决，Hardware Unboxed在部分游戏中测试了垂直同步配合帧生成的方案，帧节奏问题没有任何改善。     而且这个问题似乎并非FSR 4独有，据报道，AMD从FSR 3引入帧生成技术时就存在同样的帧节奏缺陷，至今没有修复。
