玩家可盡情發揮創意的風格讓《Minecraft》（當個創世神）成為史上最暢銷的遊戲，如今透過 NVIDIA 與微軟合作，終於能在《Minecraft》實現即時光線追蹤，運用光影的交錯打造嶄新的世界。
在《Minecraft》最新的 RTX Beta 版本中，引進全新基於物理特性的材質內容，讓物件具備可發光、金屬質感、粗糙表面或是半透明屬性，結合 DirextX 12 Ultimate API 光線追蹤帶來的全域照明、反射和透射效果，拓展創作可能性的同時也為遊戲畫面帶來截然不同的新面貌。
即時光線追蹤的運算非常複雜且繁重，因此 NVIDIA 在 Turing 架構 GPU 開闢了 RT Core 全責計算光線路徑。但 Turing 架構還有另一個秘密武器：Tensor Core，DLSS 技術就是透過它，運用人工智慧和深度學習建構更精細的空間畫面。
日前發表的 DLSS 2.0 更引進全新的統合型 AI 網路，不只處理速度加快，還不需要每個場景獨立訓練，這也讓 DLSS 更快導入《Minecraft》，分攤流處理器的工作負載，提高畫面精細度之餘也能提高每秒幀數，一舉兩得。
NVIDIA 這次與 6 位創作者合作，創建 6 個全新的《Minecraft》RTX 世界，讓玩家免費體驗光線追蹤之美。此外還有高解析素材包、物理基礎素材指南以及 Java To Bedrock 世界轉換指南，讓創作者更便於打造光線追蹤的世界。
實機操作
測試環境
- CPU：Intel Core i9-9900K
- 主機板：ASUS ROG Maximus XI Extreme
- 散熱：Thermalright Silver Arrow T8 with TF8
- 記憶體：Kingston HyperX Predator DDR4-3200 8GBx4
- 顯示卡：NVIDIA GeForce RTX 2080 SUPER Founders Edition
- 儲存：WD Black SN750 NVMe SSD 1TB
- 電源：Antec High Current Pro HCP-1200W
- 解析度：Full HD
《Minecraft》市集會開放 6 種 RTX 世界（筆者測試時已開放 ５ 種），進入該世界後可開啟 DirectX Ray Tracing（光線追蹤）和 Upscaling（DLSS），光線追蹤可調整渲染距離，預設最低是 8 個 chunks，最高可開到 24 個 chunks。
由於光線追蹤的運算負載相當吃重，即便有 RT Core 專責處理，遊戲 FPS 還是會大幅降低。這時只要再開啟 Upscaling（DLSS），靠著 Tensor Core 分攤流處理器的負擔，就能明顯將流暢度拉回不錯的檔位。
接下來為各位呈現 24 個 chunks 的 DirectX Ray Tracing 搭配 DLSS 的實機畫面。
《Color, Light and Shadow Showcase》
《Aquatic Adventure》
《Crystal Palace》
《Of Temples and Totems》
《Imagination Island》
俗話說：「沒有比較，就沒有傷害。」從以上畫面可以看到，各種場景開啟光線追蹤後，畫面的氛圍感更加濃厚，暗部場景尤為明顯。其中最特殊的是《Color, Light and Shadow Showcase》，加入光源和材質反射後，普通的房間搖身一變成了高級展示廳，真的很厲害。
在 DLSS 的幫助下，各場景開啟光線追蹤後的流暢度表現都不錯，普遍都來到 70 fps 以上。只有《Of Temples and Totems》因為物件密度高，且多為樹叢，反倒讓 CPU 的負載比較大，因而造成 fps 較低。
看完以上的展示，是不是心動了呢？即日起只要前往 Xbox Insider 中心註冊，就能下載《Minecraft》RTX Beta 測試版，擁有 NVIDIA GeForce RTX 顯示卡／GPU 的玩家只需搭配最新版驅動程式，都能立即徜徉在《Minecraft》RTX 世界中。
