Play online eSports on Linux! We could hack it more cool! - masafumi_ohta === ###### tags: `COSCUP2020` `入門` `TR412-2` {%hackmd 7CD4pdKQTa2p6Y3VqH3VrQ %} > 請從這裡開始 ## Why gaming on Linux? online game business are growing under the COVID-19 Linux is more lightwight OS than Windows ~~(哭哭 Window update)~~ 使用 windows 有時候會藍屏,跟很多問題,所以使用 Linux 靠遊戲賺錢的市場因為 COVID-19 疫情的關係而擴大 ## Linux could be gamed? * super lighttweight * easy manage with CPU speed * easy hack * still Windows libs related (32bit libraries) * still DirectX related [DirectX is coming to the Windows Subsystem for Linux ](https://devblogs.microsoft.com/directx/directx-heart-linux/) [Wine](https://www.winehq.org/) ### Online games vs Offline games Online 在硬體上的使用框架非常舊 很多硬體功能都不支援 ### Wifi or 網路線? Intel Wifi 6 AX200 adapter 比使用網路線還好(如果你有 Wifi 6 router) 畢竟網路速度在玩網路遊戲時非常重要 ~~遊戲不會使人暴力,LAG 才會~~ ### Main Memory cache is the best Linux 文件系統都用 cache 了,玩遊戲有理由不用嗎?? ### CPU/GPU usage ### Discrete or Non-discrete ### Still 32bit and Wine ## Loading testing - GPD Pocket 2 - GPD Win Max 2 - Thinkpad E945 使用 [Secondlife](https://secondlife.com/) 這款遊戲做測試 ## Summary * eSports 使用 linux 可以 tune 很多 resources * Memory * CPU * Cache * 即使是最新的線上遊戲,依然不太需要CPU/GPU效能 * Still using on 32bit libraries and Wibdow libraries... ## Q & A 1. SteamOS 使用經驗 有使用過,但大部分的遊戲在 SteamOS 上都不太行,但少數遊戲的確不錯。 不過大致上還是很難用,所以才自己另外作環境去 test 2. 在 Linux 發展遊戲相關原生生態係的可能性? 他們也想做生態系,但不太行,他們是 CPU and GPU 堆疊作外部虛擬(?),目前透過 wine 模擬可達到 Windows 原生約70%的效能表現,跑在 Linux 上只有 30%,效能很低 3. 如果使用 Vulkan api 去實作,效能會變好嗎? 他們也想做,Vulkan 支援還不是很多,目前跨平台應用上還是 OpenGL 較多 4.
