HIS4850玩紅色警戒2效能低落 - 顯卡

我的配備是

CPU:720BE

MB: MA785G-UD3H

RAM:2G*2

HDD: WD640G AAKS

VGA:HIS4850 512MB

DRIVE 9.8

PSU:E80 400W 帝海代理

我玩紅色警戒2時

在捲動畫面會頓頓的

我本來以為會不會是POWERPLAY的問題

我用RIVA鎖住頻率之後

還是會頓

但好像沒這麼嚴重了(錯覺嗎@@

我用P TEST 7.0測試如下

2D Graphics Mark

Graphics 2D - Transparent Vectors

想當然我是看不出所以然來

所以特來請教

因為我原本用MSI的4830玩RA2是不會頓的

DRIVE 9.7

版子是MA780G-UD3H

是2D支援度太差還是驅動程式的問題呢?
