NVIDIA 於昨天發布了新版本驅動程式 GeForce 456.55 WHQL,據稱提高 RTX 30 系列顯卡的穩定性,因為之前有部分 RTX 3090、RTX 3080 顯卡用戶表示遊戲時會閃退回桌面,有多數媒體直指是電容用料的鍋,不過似乎全配置 POSCAP 或全 MLCC 或其他搭配都有災情傳出。

比較令人好奇的是這個 456.55 較為穩定的版本驅動是否影響效能,以下來實測一下與之前第一版正式版 456.38 的差異。
測試平台
CPU: Intel Core i9-10900K 無超頻
CPU Cooler: MSI MAG CoreLaquid 360R
RAM: HyperX DDR4-3466 8GBx2
MB: GIGABYTE Z490 AORUS ELITE AC
VGA: GIGABYTE RTX 3080 Gaming OC 10G
VGA Driver:456.55 & 456.38
HDD: KLEVV N610 1TB、Seagate 2TB
PSU: GIGABYTE P750GM
OS: Windows 10 64bit
3DMark Fire Strike Extreme

3DMark DLSS
456.38
DLSS off:54.19 FPS
DLSS on:75.70 FPS

456.55
DLSS off:53.88 FPS
DLSS on:75.34 FPS

《刺客教條:奧德賽》
解析度刻意拉低到1920×1080,張數多差異自然會比較明顯一點。畫面套用最高設定。
456.38:96

456.55:94

效能上大致上可以看到,3DMark 的部分圖形分數似乎差異不大,有差異的 Time Spy 、DLSS 只在0.4~0.6%效能損失,遊戲《刺客教條:奧德賽》差兩張,大約是2%。
至於這版驅動改變了甚麼?在測試《刺客教條:奧德賽》時開啟 GPU-Z 監測了一下,大致上時脈似乎在多數時間沒太大改變,較有差異的部分在於 GPU 電壓,新版本的驅動 456.55 似乎降低了一些電壓,測試時為1.068V,偶爾掉到1.062V,而舊版 456.38,測試時電壓1.075V,偶爾拉高至1.081V。
