GeForce GTX 970s seem to have an issue using all 4GB of VRAM, Nvidia looking
into it - NeoGAF
http://neogaf.com/showthread.php?t=977645
國外玩家們在最近操顯卡時發現只要遊戲吃的記憶體超過 3.5GB 時 fps 就會驟降
也有的人表示某些遊戲不經過特別的設定組合 (例如開到1440P, 反鋸齒故意開MSAA 8x)
的話就吃不過 3.5GB
原因目前眾說紛紜, 自記憶體廠牌 (三星或Hynix), driver/BIOS issue, 甚至是硬體本
身的設計有問題都有 (遮蔽單元來分等級玩壞了?)
目前國外幾個主要討論區都有討論這個問題, 官方也有表示注意到並會開始調查 (可見上
方 neogaf 討論串內的傳送門)
... 心中還在肖想開學前添購一張970, 現在先繼續抱著760過年qq
edit: 想要試試自己的顯卡有沒有問題的先說明一下 nai Benchmark
"並不能直接反映顯卡問題並作為直接證據參考"
這個程式其原理是借用CUDA函式庫來一一使用記憶體內的每個區塊並記錄頻寬大小
(所以AMD的卡不適用這個測試)
nai Benchmark 討論串 (德文注意)
