隨著《NBA 2K27》上市，NVIDIA DLSS 5 實測正式解禁，一起來看看實際遊戲畫面表現吧。
實機畫面
從實際畫面可以看到，未開啟 DLSS 5 時，球員皮膚與肌肉線條較為平淡，光影效果也比較死板。
開啟 DLSS 5 後，球員肌肉與衣物的紋理更細緻，汗水與皮膚的交互更明顯，光影與次表面散射讓整體畫面看起來更立體。而且不只球員，連後方看台觀眾的臉部輪廓也更清晰立體。
效能分析
在 4K 2160p 解析度環境下畫面特效全開，原生畫面在 GeForce RTX 5090 可跑出 215 fps 左右，但若開啟 DLSS 5 Neural Rendering 神經渲染，畫面流暢度會降至 86 fps，顯然神經渲染需要動用大量的 GPU 算力。
還好神經渲染可以連同 DLSS 超解析度和補幀功能一起開。神經渲染搭配 DLSS 超解析度畫質模式再加上 4 倍補幀，畫面流暢度可達 274 fps，若開啟 6 倍補幀，畫面流暢度甚至可以突破 380 fps。
用同樣的畫質與神經渲染設定來看其他 GPU 表現，4 倍補幀的設定下，4K 解析度 RTX 5080 可跑出接近 180 fps、RTX 5070 Ti 可跑出接近 150 fps、RTX 5070 近 110 fps，RTX 5060 也還有 77 fps。
若改用 6 倍補幀，RTX 5080 接近 240 fps、RTX 5070 Ti 有 200 fps、RTX 5070 有 150 fps、RTX 5060 Ti 也有106 fps。
總結
從畫面效果來看，DLSS 5 確實沒有改變遊戲畫風，它能呈現更寫實且細緻的畫面。更重要的是，DLSS 5 的畫面風格其實是遊戲開發者想要呈現的效果，玩家們不必擔心畫風詭異突變。
效能方面，DLSS 5 使用的神經渲染雖然會動用大量算力，但它用更有效率的方式免除傳統材質渲染可能吞噬的大量記憶空間與頻寬。隨著演算法不斷進化，也許未來 DLSS 5 的會有更好的性能成長，我們就拭目以待囉！
你喜歡哪些 NVIDIA DLSS 帶來的畫面改動？
- DLSS 1 / 2：超解析度放大
- DLSS 3 / 4 / 4.5：補幀、4x / 6x 多畫格生成
- DLSS 3.5 / 4.5：光線重建
- DLSS 5 神經渲染畫面更寫實
- 只要有改畫面的我都不喜歡啦
