'''[[GeForce Now]]'''是由[[NVIDIA]]所运营的遊戲（[[雲遊戲]]）品牌。[[GeForce Now]]的前身为'''[[NVIDIA GRID]]'''，GeForce Now的[[Nvidia Shield]]版本于2013年投入测试，2015年12月30日，GeForce Now這一名稱正式啟用。

[[GeForce Now]]透過[[订阅]]向用户提供寄存于[[NVIDIA]][[服务器]]上的[[游戏库]]的无限制使用服务并透过[[串流]]传输给订阅者。特定游戏可通过“[[雲端遊玩]]([[即買即用]])”（[[Buy & Play]]）进行体验。此服务早期仅限[[Shield Portable]]、[[Shield Tablet]]和[[SHIELD TV]]设备的用户使用。<ref name="anandtech-gridnow">{{cite web|title=NVIDIA's GeForce NOW - GRID Cloud Gaming Service Goes the Subscription Way|url=http://www.anandtech.com/show/9673/nvidias-geforce-now-grid-cloud-gaming-service-goes-the-subscription-way|website=Anandtech|publisher=Purch, Inc.|accessdate=2017-05-04|archive-date=2017-03-10|archive-url=https://web.archive.org/web/20170310060410/http://www.anandtech.com/show/9673/nvidias-geforce-now-grid-cloud-gaming-service-goes-the-subscription-way|dead-url=no}}</ref><ref>{{Cite web|url=https://venturebeat.com/2015/09/30/nvidia-finally-launches-geforce-now-cloud-gaming-for-shield-set-top-console/|title=Nvidia finally launches GeForce Now cloud gaming for Shield set-top console|website=VentureBeat|access-date=2016-07-18|archive-date=2016-08-31|archive-url=https://web.archive.org/web/20160831011253/http://venturebeat.com/2015/09/30/nvidia-finally-launches-geforce-now-cloud-gaming-for-shield-set-top-console/|dead-url=no}}</ref><ref name="#1">{{Cite web |url=https://udn.com/news/story/10222/4781634 |title=存档副本 |accessdate=2020-10-15 |archive-date=2020-10-18 |archive-url=https://web.archive.org/web/20201018200308/https://udn.com/news/story/10222/4781634 |dead-url=no }}</ref>

2017年1月，[[NVIDIA]]透露了同样称为[[GeForce Now]]的[[个人电脑|PC]]、[[MacOS|Mac]][[云端游戏服务]]。这是一款使用[[远程桌面软件|远程桌面]]技术向用户提供虚拟机租赁的服务，用户可以从数位发行平台上安装PC游戏并远程游玩。与Shield版本一样，虚拟桌面从英伟达服务器中通过[[流媒体]]传输给用户。

Geforce Now現在可以在[[个人电脑|PC]]([[Windows]])、[[MacOS|Mac]]、[[Android]]上遊玩，而[[iOS]]因為需要通過[[蘋果]]審查平台提供的遊戲內容，故暫無上架[[App Store]]，但能夠透過[[Safari]]進行串流。<ref>https://www.nvidia.com/en-us/geforce/forums/gfn-general-chat/20/340263/geforce-now-on-ios/</ref><ref>{{Cite web |url=https://udn.com/news/story/10222/4855938|title=存檔副本|accessdate=2020-10-15 |archive-date=2020-11-17 |archive-url=https://web.archive.org/web/20201117072841/https://udn.com/news/story/10222/4855938 |dead-url=yes }}</ref>

[[GeForce Now]]在[[台灣]]的合作夥伴為[[台灣大哥大]]，由[[台灣大哥大]]代理運營伺服器、金流服務、客服、推廣等各項事務。<ref>{{Cite web|title=台灣大哥大 GeForce NOW 官網|url=https://gfn.taiwanmobile.com/portal/index|accessdate=2023-03-14 |archive-date=2021-01-30 |archive-url=https://web.archive.org/web/20210130010724/https://gfn.taiwanmobile.com/portal/index |dead-url=no }}</ref>

== 特性 ==

GeForce Now由位于[[北美洲]]与[[欧洲]]的数据中心服务器网络组成并向这些地区的用户提供GeForce Now游戏库服务。<ref>{{Cite web|url=http://www.pcworld.com/article/2986766/home-players/nvidia-geforce-now-aims-to-be-the-netflix-of-games-for-just-8-bucks.html|title=Nvidia GeForce Now aims to be the 'Netflix of games' for just 8 bucks a month|access-date=2016-07-18|archive-date=2017-12-15|archive-url=https://web.archive.org/web/20171215011051/https://www.pcworld.com/article/2986766/home-players/nvidia-geforce-now-aims-to-be-the-netflix-of-games-for-just-8-bucks.html|dead-url=no}}</ref>这些服务器使用[[GeForce]][[显示卡|显卡]]，串流游戏最多可达到60帧每秒的[[1080p]]分辨率输出。英伟达对于1080p/60fps的串流推荐50 Mbps的网络连接速度，但服务器也可在720p/60fps每秒的情况下以25 Mbps的速度传输，而720p/30fps每秒的串流仅需10 Mbps。服务器使用[[自適性串流]]技术根据頻寬平衡画面品質。<ref name="polygon-warnersega" /><ref>{{Cite web|url=http://www.androidpolice.com/2015/10/01/hands-on-with-nvidias-geforce-now-streaming-service-is-the-world-finally-ready-for-a-game-streaming-service/|title=Hands-On With NVIDIA GeForce Now: Is The World Finally Ready For A Game Streaming Service?|date=2015-10-01|website=Android Police|access-date=2016-07-18|archive-date=2020-12-12|archive-url=https://web.archive.org/web/20201212055033/https://www.androidpolice.com/2015/10/01/hands-on-with-nvidias-geforce-now-streaming-service-is-the-world-finally-ready-for-a-game-streaming-service/|dead-url=no}}</ref>随着时间变化，服务器端硬件将更新以提高串流品質。<ref name="anandtech-gridnow" /><ref>{{Cite web|url=http://www.tomsguide.com/us/geforce-now-game-streaming,review-3113.html|title=GeForce Now Review: Game Streaming Done (Mostly) Right - GeForce Now Review: Game Streaming Done (Mostly) Right|date=2015-10-09|access-date=2016-07-18|archive-date=2020-12-13|archive-url=https://web.archive.org/web/20201213050433/https://www.tomsguide.com/us/geforce-now-game-streaming,review-3113.html|dead-url=no}}</ref>

== 游戏库 ==

截止2016年3月，GeForce Now库内包含了超过80个游戏；在2016年的[[游戏开发者大会]]上，英伟达宣布与[[世嘉]]和[[華納兄弟互動娛樂]]达成授权协议。游戏库中的大量游戏都可在已订阅的情况下进行串流。然而部分游戏仅能通过“支付游玩”（Buy & Play），即用户必须购买此游戏才能进行游玩。<ref name="polygon-warnersega">{{Cite web|url=http://www.polygon.com/2016/3/15/11222650/nvidia-geforce-now-sega-warner-bros-developer-program|title=GeForce Now, Nvidia's 'Netflix for games,' expands with Sega and Warner Bros.|last=Sarkar|first=Samit|date=2016-03-15|website=Polygon|language=en-US|access-date=2016-07-18|archive-date=2020-11-08|archive-url=https://web.archive.org/web/20201108161302/http://www.polygon.com/2016/3/15/11222650/nvidia-geforce-now-sega-warner-bros-developer-program|dead-url=no}}</ref><ref name="anandtech-gridnow" />

== GeForce Now桌面版 ==

在2017年1月的[[消費電子展]]上，英伟达发布了GeForce Now的PC版与麦金塔版本。不像适用于英伟达Shield版本（此版本中英伟达将云游戏服务像[[Netflix]]一样宣传），<ref name="polygon-warnersega" />这是一款独立发售的服务，用户可以租赁连接到搭载GeForce GTX显卡的[[Microsoft Windows]]桌面环境的[[远程桌面程式|远程桌面]]权限。用户可以安装诸如[[Steam]]和[[Origin (电子游戏平台)|Origin]]的数位发行客户端至远程桌面下载并允许已支付的或免费的游戏。此服务以游玩分钟扣除服务点数计费；共有两个价位，分别是[[NVIDIA GeForce 10系列]]性能和[[GTX 1080]]级性能的价格。英伟达将此服务的目标受众定为欲游玩不兼容他们所拥有电脑的游戏的玩家，比如笔记本电脑和低端电脑用户。<ref name="extech-geforcenowpc">{{cite web|title=Nvidia announces GeForce Now streaming service for PCs with pay-per-minute gaming|url=https://www.extremetech.com/gaming/242165-nvidia-announced-geforce-now-streaming-service-pcs-pay-per-minute-gaming|website=ExtremeTech|accessdate=2017-05-05|archive-date=2021-01-13|archive-url=https://web.archive.org/web/20210113085043/https://www.extremetech.com/gaming/242165-nvidia-announced-geforce-now-streaming-service-pcs-pay-per-minute-gaming|dead-url=no}}</ref><ref name="ars-geforcenowpc">{{cite web|title=Nvidia brings GeForce Now game streaming to any PC or Mac|url=https://arstechnica.com/gaming/2017/01/nvidia-geforce-now-streaming-pc-mac-price-release-date/|website=Ars Technica|accessdate=2017-05-05|archive-date=2021-01-13|archive-url=https://web.archive.org/web/20210113121000/https://arstechnica.com/gaming/2017/01/nvidia-geforce-now-streaming-pc-mac-price-release-date/|dead-url=no}}</ref><ref name="cnet-geforcenow17">{{cite web|title=Did Nvidia just fix the biggest issue with its GeForce Now cloud gaming service?|url=https://www.cnet.com/news/nvidia-geforce-now-relaunch-steam-ces-2017/|website=CNET|accessdate=2017-05-05|archive-date=2021-02-02|archive-url=https://web.archive.org/web/20210202015046/https://www.cnet.com/news/nvidia-geforce-now-relaunch-steam-ces-2017/|dead-url=no}}</ref>

英伟达宣布于2017年3月开始测试服务，但随后便悄悄地取消了这一计划。在2017年5月的财报中，英伟达CEO[[黃仁勳]]透露测试版将“很快”可用，但英伟达“仍需要数年才能在支出与服务品質和虚拟化游戏主机的普遍性间找到正确的平衡”。<ref name="pcw-nonow">{{cite web|title=GeForce Now, only later: Nvidia game streaming will need 'several years' to scale|url=http://www.pcworld.com/article/3195890/gaming/geforce-now-only-later-nvidia-game-streaming-will-need-several-years-to-scale.html|website=PC World|accessdate=2017-05-26|archive-date=2017-08-15|archive-url=https://web.archive.org/web/20170815164044/http://www.pcworld.com/article/3195890/gaming/geforce-now-only-later-nvidia-game-streaming-will-need-several-years-to-scale.html|dead-url=no}}</ref>2017年10月末，英伟达发布了免费的公测版本，仅限北美和欧洲的麦金塔英语用户。<ref name="bit-net-geforcenow-macbeta-launch">{{cite web|title=Nvidia launches GeForce Now macOS beta|url=https://www.bit-tech.net/news/gaming/apple/nvidia-launches-geforce-now-macos-beta/1/|website=bit-net|accessdate=2017-11-15|archive-date=2020-10-27|archive-url=https://web.archive.org/web/20201027225756/https://www.bit-tech.net/news/gaming/apple/nvidia-launches-geforce-now-macos-beta/1/|dead-url=no}}</ref><ref>{{cite web|title=GeForce NOW for Mac FAQs|url=https://www.nvidia.com/en-us/geforce/products/geforce-now/mac-pc/faq/|website=Nvidia|accessdate=2017-11-15|archive-date=2018-07-13|archive-url=https://web.archive.org/web/20180713031547/https://www.nvidia.com/en-us/geforce/products/geforce-now/mac-pc/faq/|dead-url=no}}</ref>2018年1月，英伟达将PC用户加入了英伟达GeForce Now服务中。<ref>{{Cite news|url=https://www.theverge.com/2018/1/8/16865480/nvidia-geforce-now-windows-beta-app-gaming-pc-ces-2018|title=This app can transform your cheap laptop into a gaming PC|work=The Verge|access-date=2018-02-27|archive-date=2020-11-30|archive-url=https://web.archive.org/web/20201130171754/https://www.theverge.com/2018/1/8/16865480/nvidia-geforce-now-windows-beta-app-gaming-pc-ces-2018|dead-url=no}}</ref>。2020年8月18日，英伟达GeForce Now在ChromeOS上开启beta测试<ref>{{cite web |author1=Andrew Fear |title=GeForce NOW on Chromebook: Bring Your Games with You |url=https://blogs.nvidia.com/blog/2020/08/18/geforce-now-open-a-chromebook/ |website=The Official NVIDIA Blog |accessdate=2020-08-19 |language=en |date=2020-08-18 |archive-date=2020-12-20 |archive-url=https://web.archive.org/web/20201220081230/https://blogs.nvidia.com/blog/2020/08/18/geforce-now-open-a-chromebook/ |dead-url=no }}</ref>。

2021年1月30日，[[XDA]]发现GeForce Now 2.0.27可以在Windows和macOS上的Chrome浏览器運行，不過仍舊為beta版<ref>{{cite news |title=GeForce Now 可以直接在 Chrome 浏览器里游玩了 |url=https://cn.engadget.com/geforce-now-browser-cloud-gaming-071337959.html |accessdate=2021-01-30 |archive-date=2021-04-13 |archive-url=https://web.archive.org/web/20210413115024/https://cn.engadget.com/geforce-now-browser-cloud-gaming-071337959.html }}</ref>。

2021年3月，GeForce NOW升級，不限制平台、不需要高性能显卡情況下每月9.99美元就可以體驗1100多款游戏。不過截至11月，GeForce NOW游戏帧率有所下調，多款游戏不到60fps，甚至只有45fps<ref>{{cite news |title=NVIDIA确认限制部分GeForce NOW游戏性能：最高不超55fps |url=https://news.mydrivers.com/1/796/796190.htm |accessdate=2021-11-15 |archive-date=2021-11-24 |archive-url=https://web.archive.org/web/20211124135346/https://news.mydrivers.com/1/796/796190.htm }}</ref>。
