遊戲開發商 CD Projekt RED (CDPR) 的遊戲開發商 CD Projekt RED (CDPR) 重新構思了《The Witcher 3》中的迷你遊戲《GWENT: The Witcher Card Game》，2020 年 3 月在 Google Play 推出免付費的獨立遊戲。初始檔案大小較大，並需要額外裝置儲存空間的定期更新，使用者通常需要重新安裝完整遊戲，才能取得更新版本。這是遊戲社群最容易感到挫折的地方。為協助差異化修補作業，CDPR 已導入 Play Asset Delivery 獲得不錯的成果。

具體措施
CDPR 是導入 Play Asset Delivery (PAD) 的早期合作夥伴。該公司提供三種不同的提供模式，一開始是以隨選方式實作，以便在遊戲執行時安裝資產包。隨後，CDPR 卻採用快速追蹤提供功能，並在遊戲安裝後，自動提供超過 40 MB 的資產包，每個大小的範圍從 4 MB 到 160 MB。使用快速追蹤的好處在於，即使使用者未開啟遊戲，系統仍會在背景執行下載作業。下次開啟時，遊戲會更新並可立即暢玩。首席生產者 Maciej Włodarkiewicz 表示：「這是唯一可靠的解決方案，能為我們提供所有主要功能：差異修補、遊戲內下載和動態更新，以及動態更新。
成果
CDPR 特別滿意 PAD 簡化應用程式更新流程的方式。藉助 Play Asset Delivery 自動更新和差異修補，更新率大幅提升並減少重新安裝。這樣就能將更新大小縮減 90%。過去需要下載以及超過 2 GB 的額外儲存空間，現在只需要幾百 MB。

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)."]]
