AMD Radeon RX 7900專用22.12.2驅動修復改善影片播放功率

昨天AMD發布了最新的Radeon Software Adrenalin (22.12.2) WHQL驅動，適用於Radeon RX 7900系列顯示卡。

在發布期間AMD Radeon RX 7900系列顯示卡在空閒和正常影片播放期間的功耗比競爭對手高得多。在多顯示器和影片播放中，功耗有時比NVIDIA的RTX 40系列顯示卡高4倍。此外儘管AMD聲稱能效比RDNA2提高54%，但採用RDNA3的Radeon RX 7900系列顯示卡與這個數字相去甚遠。但隨著新驅動的發布，AMD正在解決其中一些問題，並承諾在未來進一步提高效率。以下是AMD Radeon Software Adrenalin 22.12.2 WHQL驅動的更新日誌和下載：
