你好像沒看清楚我的回文，GM200/GM204/GM206都達到Direct3D 12_0和12_1的feature level要求，包括你說的980。
而且能不能開通常不是遊戲玩家決定而是開發廠商設定的。
Microsoft的文件寫得很明確：
•A GPU that allows a device to be created meets or exceeds the functionality of that feature level.
•A feature level always includes the functionality of previous or lower feature levels.
•A feature level does not imply performance, only functionality. Performance is dependent on hardware implementation.

我覺得對遊戲玩家而言，benchmark才是比較有意義的判斷依據。
