※ 引述《oneyear (mm)》之銘言:
: 一個的外行遊戲阿宅想問
: 如果我不想換新電腦
: 又不希望之後玩現在有的遊戲因為 CPU降效能跑不動
: 是不是應該現在把微軟的自動更新給關了
: 以免之後哪天 微軟發布更新後 造成CPU少個5~30%效能後
: 原本能跑的遊戲變成跑不動了...
: 還是說可以再觀望?
: PS. 目前的OS是WIN7
消費級的就先不用嚇自己
因為
1. user mode的計算不會變慢
壓檔跟跑分是沒有因為這樣分數洗牌的
2. I/O syscall要多花時間所以變慢
但你自己的應用會是重度I/O嗎
而且原本disk如果是機械式硬碟 那麼降低的相對比例
就很有限(一次都要花超過10ms, 軟體修正耗掉幾百個us
只拖慢一點點)
補充 現有的linux patch沒有造成遊戲性能下降
但這點並不是說證明這問題不會造成遊戲性能下降
而是因為driver架構上 這問題要等待GPU晶片商做最終確認
