游戏开发商 CD Projekt RED (CDPR) 位于波兰华沙,他们重新构思了自己的迷你游戏《巫师 3》、《巫师之昆特牌》,并于 2020 年 3 月在 Google Play 上以独立的免费畅玩形式发布。由于初始文件较大,且定期更新需要额外的设备存储空间,用户通常必须重新安装完整版游戏,才能获得更新的版本。这是游戏社区中最突出的挫败点。为了帮助进行差分修补,CDPR 通过实现 Play Asset Delivery 取得了巨大的成功。

策略
CDPR 是实现 Play Asset Delivery (PAD) 的早期合作伙伴。提供三种不同的分发模式后,CDPR 最初实现了按需分发,可在游戏运行期间安装资源包。CDPR 随后采用了快速跟进式分发方法,在游戏安装完成后,自动分发 40 多个资源包,每个资源包的大小介于 4 MB 到 160 MB 之间。使用快速跟进式分发方法的好处是,它支持后台下载,即使用户尚未打开游戏也是如此。因此,在用户下次打开游戏时,游戏已更新完毕,用户可以立即进入游戏。“这是唯一能够为我们提供所有关键功能的可靠解决方案:增量修补、游戏内和商店内下载以及动态更新。”首席制作人 Maciej Włodarkiewicz 说道。
成果
CDPR 特别满意 PAD 帮助简化应用更新的方式。得益于 Play Asset Delivery 的自动更新和增量修补,CDPR 发现游戏更新频率显著提高,而重新安装量呈减少趋势。鉴于此,CDPR 得以将其更新大小缩减 90%。以前需要下载和额外存储空间超过 2GB 的更新,现在只需几百 MB 即可。

This was the most prominent point of frustration among the\ngame's community. In an effort to help with differential patching,\nCDPR has seen great success by implementing Play Asset Delivery.\n**GWENT: The Witcher Card Game by CD Projekt RED**\n\nWhat they did\n-------------\n\nCDPR was an early partner to implement Play Asset Delivery (PAD). With three\ndifferent delivery modes available, they initially implemented on-demand,\nallowing for asset packs to be installed while the game is running. CDPR then\nadopted fast-follow delivery, automatically serving over 40 asset packs that\nrange in size from 4 MB to 160 MB each, as soon as the game was installed.\nThe benefit of using fast-follow is it permits downloads to happen in the\nbackground, even if the user has not opened the game. Upon the next open, the\ngame is updated and ready to be played right away. \"It's the only reliable\nsolution that provides us with all key features: delta patching, in-game and\nin-store downloading, and dynamic updates,\" said Maciej Włodarkiewicz,\nLead Producer.\n\nResults\n-------\n\nCDPR was particularly pleased with the way PAD helped streamline app updates.\nThey saw major improvement in update rates and reduction in reinstalls thanks\nto Play Asset Delivery auto-updates and delta patching. With this, CDPR was\nable to reduce their update size by 90%. An update that used to require download\nand extra storage space of more than 2GB now only takes a couple hundred MB.\n\nAlmost immediately after implementing PAD, CDPR saw a reduction of reinstalls\nand an increase in the speed of players updating to the latest app version.\nBetween app versions 7.0 to 7.1, they saw almost a 10% lift in the percentage of\nactive devices updated to the latest app version and a 4.8x reduction in\nuninstalls on day 1 of the new version release. Using fast-follow and background\ndownloads, GWENT was able to save users an average of 8 minutes of idle wait\ntime, compared to using a content delivery network.\n\nGet started\n-----------\n\nGet started today by learning more about [Play Asset Delivery](/guide/app-bundle/asset-delivery)."]]
