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

老千

一 |     8月24日消息,Hardware Unboxed近日使用慢动作摄像机对AMD FSR 4帧生成技术进行了帧节奏测试,结果显示FSR 4存在严重的画面抖动问题。     帧生成技术的原理是在两个真实渲染帧之间插入一个AI生成的中间帧,从而把帧率翻倍,比如基础帧率60fps,开启帧生成后输出120fps。    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。    

As physicians who care for children and families, our mission is to keep our patients healthy and help them thrive.
With many students heading back to school soon (and some having already started classes), we know all too well what it’s like for families to navigate this changing season – and importantly, to try to stay healthy. Along with the excitement and energy that each new school year brings, this is also a time of exposure to all the viruses that we typically see during the colder months. This year, that includes colds, the flu, respiratory syncytial virus (or RSV) and COVID-19.
As families prepare for the year ahead, it’s important that children’s immune systems are also prepared to detect and resist viruses so that they can stay healthy and thrive. Just like how software updates to your phone or computer keep things in working order, vaccines help your body’s immune system work better. We also know that when everyone can access recommended immunizations on time, it stops preventable diseases from spreading through our communities.
Vaccines are one of the greatest medical advances in history. Thanks to widespread immunization, we have eradicated or controlled many diseases that once caused pain, suffering and even death for countless children – from smallpox and polio to tetanus and measles. Plus, when children stay healthy and free of such debilitating diseases, they can succeed by staying in school and safely participating in activities like sports and other after-school programs. This continuity helps improve children’s social and emotional development and their entire quality of life.
Unfortunately, parents must currently try to find guidance about their child’s health in a sea of mis- and disinformation. In the age of social media, misinformation about many topics is rampant, and vaccines are no exception. We encourage everyone to seek information from a trusted source, like their family physician or pediatrician – the same way that we work together with parents to offer guidance on other important topics like healthy nutrition, injury prevention and so much more.
At that same time, we do need better ways to talk about vaccines, along with ways to help parents identify accurate sources of information that they can trust. We must also ensure that vaccines are widely available, easy to find and affordable to everyone.
Right now, the U.S. is lagging behind. In 2022, only 45.9% of children received a flu shot, down from 53.1% in 2019, according to data from the Centers for Disease Control and Prevention. This is compounded by research that showed a two-year decline in children receiving routine vaccinations during the COVID-19 pandemic.
Also concerning is CDC research showing that 8% of children had not had a well-child checkup within the last year – and that 6% didn’t have a doctor’s visit at all. A recent UNICEF report also shows 67 million children across the world missed out on one or more vaccinations over the last three years. These children are missing opportunities for immunizations as well as vital guidance on mental health, nutrition and other areas of child health and development.
These statistics are even more reason for parents, physicians and policymakers to ramp up vaccine education and ensure that children and their families can access vaccines and other routine medical care.
As physicians who care for families and who watch children grow up over many years, pediatricians and family physicians are well-positioned to help patients and their parents navigate challenges in getting vaccines. In addition to helping overcome barriers like lack of insurance or transportation, we can also serve as sources of accurate information. We can be a backstop against the rampant misinformation parents encounter in social media and a sounding board for their questions.
But physicians cannot do this alone. Policymakers must recognize the need to help families who qualify stay enrolled in Medicaid and to protect programs like the Children’s Health Insurance Program, which offers coverage for those who might not be eligible for Medicaid. We must expand the number of hospitals and clinicians who participate in the federally funded Vaccines for Children program, which today offers vaccines to nearly half the nation’s children. This program is critical because it helps ensure vaccine and health equity. And we must also ensure that physicians have the support they need to continue physically storing, administering and counseling families on vaccines.
In the end, we all share a collective responsibility to safeguard the health of our nation’s children and the health of the public. As your doctors, we know that we are all healthier when everyone is vaccinated.
。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。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。
