明修棧道暗渡陳倉 催化劑5.4搶先測試
顯示芯片制造業(yè)為了讓人們理解起來容易,借用了很多汽車上的名字,比如驅(qū)動汽車的“Engine”(引擎),驅(qū)動硬件的“Driver”(驅(qū)動/司機)。Driver在汽車上叫做司機,但是在電腦上叫做驅(qū)動程序,人們習(xí)慣簡稱為“驅(qū)動”。驅(qū)動程序是軟件,負(fù)責(zé)應(yīng)用軟件和硬件的連接,驅(qū)動程序的好壞能夠很大程度上影響硬件的發(fā)揮。
上周末,ATI發(fā)布了他們最新的催化劑5.4版的驅(qū)動,我們今天就來看看這版驅(qū)動的表現(xiàn)。
在ATI的官方主頁,對這款驅(qū)動的改進(jìn)的部分描述的是:
- 3DMark2001: A black screen is no longer displayed when launching 3DMark2001 after launching Aquamark3 when the CATALYST™ CONTROL CENTER is installed (解決了先運行AquaMark3后運行3DMark2001時出現(xiàn)黑屏的問題。)
- Pacific Fighters: Playing the game after playing any track for a short period of time and having the landscape detail set to perfect no longer results in the clouds becoming blocking when flying (解決了在太平洋空戰(zhàn)中云的效果的問題)
- Sail Simulator 4: Attempting to play the game under Windows XP with an ATI RADEON™ 9800 XT installed no longer results in the operating system failing to respond and rebooting (解決了使用98XT在WinXP下玩模擬航海4無響應(yīng)的問題)
- SolidWorks 2004: Display corruption is no longer noticed when setting the AA to 6X and AF to 16X (解決了SolidWorks 2004中的問題)
- Splinter Cell Chaos Theory: Depth buffer corruption noticed on the ATI RADEON™ X800 PRO is now resolved (解決了X800Pro運行分裂細(xì)胞3出現(xiàn)的深度緩沖失效的問題)
- Star Wars Knights of the Old Republic: Loading the Dantooine level of the game under Windows XP no longer results in slow game performance (解決了星球大戰(zhàn)之共和國的騎士的速度問題)
下面還有一些跟游戲無關(guān)的改進(jìn):
- Using the ATI Problem Report Wizard under Windows XP SP2 with an ATI RADEON™ X850 XT installed no longer results in an error message appearing when clicking the Finish button for the problem report
- CATALYST™ CONTROL CENTER: An option to select Yes or No to changes made in SMARTGART™ is now displayed when clicking the Apply button in SMARTGART™
- CATALYST™ CONTROL CENTER: Playing a video clip in the background and entering the Overlay page found in the Video section no longer results in the default value for the Hue not being reapplied unless the CATALYST™ CONTROL™ CENTER is closed and re-launched
- CATALYST™ CONTROL CENTER: Selecting Germany as the language no longer results in some of the text overlapping each other on the Unlock button
- CATALYST™ CONTROL CENTER: Selecting Netherlands (Dutch) as the language no longer results in some of the text in the Hotkey manager being cut off
- CATALYST™ CONTROL CENTER: The Bus setting information is now displayed in the Graphic Hardware section of the Information Center found
- CATALYST™ CONTROL CENTER: The Display Manager Wizard no longer contains a Component Video single display setting message, when multi-display desktop mode is selected
- CATALYST™ CONTROL CENTER: Custom modes can only be applied if the display device can support the mode selected
- Attempting to apply a higher refresh rate to a non-DDC monitor no longer results in the refresh rate reverting to 60hz.
- SXGA+ LCD panel flicker is no longer noticed when the frame buffer (UMA size) is set to 32MB or 64MB
由于是正式版的驅(qū)動,所以我們看出ATI還是用了很多心思的,這也正是消費者需要的,因為對于顯示芯片廠商,驅(qū)動程序幾乎是唯一的售后服務(wù)形式。
驅(qū)動程序?qū)τ谛阅艿挠绊懖⒉粫貏e大,這是我們都知道的,就像是舒馬赫開奧托肯定比一個二流車手開跑車慢,何況驅(qū)動之間的差別并不一定像舒馬赫和二流車手那么大。
所以我們的測試就要求環(huán)境非常嚴(yán)謹(jǐn),我們使用GHOST備份了一個干凈的操作系統(tǒng),每次測試都重新安裝驅(qū)動和軟件。
硬件系統(tǒng) | |
處 理 器 | AMD Athlon64 3800+ |
主 板 | 華碩 A8NSLI |

為了盡可能體現(xiàn)出驅(qū)動的差別,所以我們采用了最好的跑車,也就是Radeon X850 XT。










1、用WinRAR打開Doom3 pak000.pk4壓縮包,在WinRAR文件瀏覽框當(dāng)中找到interaction.vfp文件,用記事本打開interaction.vfp文件;
2、在interaction.vfp當(dāng)中找到以下代碼:
PARAM subOne = { -1, -1, -1, -1 };
PARAM scaleTwo = { 2, 2, 2, 2 };
在這段代碼下面加上PARAM specExp = { 16, 0, 0, 0 }; ,現(xiàn)在這段代碼應(yīng)該是:
PARAM subOne = { -1, -1, -1, -1 };
PARAM scaleTwo = { 2, 2, 2, 2 };
PARAM specExp = { 16, 0, 0, 0 };
3、將以下代碼:
# perform a dependent table read for the specular falloff
TEX R1, specular, texture[6], 2D;
修改為:
# perform a dependent table read for the specular falloff
# TEX R1, specular, texture[6], 2D;
POW R1, specular.x, specExp.x;
4、保存interaction.vfp文件,WinRAR會詢問是否更新Doom3 pak000.pk4壓縮包當(dāng)中的文件,選擇“是”。至此修改完成。
根據(jù)Humus自己測試,在1280×1024分辨率下,修改前的fps是34fps,修改之后的fps是48fps。
今天我們的測試過程并沒有發(fā)現(xiàn)成績有大幅的提升,說明ATI并沒有在這個版本的驅(qū)動中采用這種方法,而是真的在挖掘顯示芯片性能的方面下了功夫。
在文章的前面我們看到ATI對這款驅(qū)動的描述中沒有提及Doom3的性能提升,看來這是一個“明修棧道,暗渡陳倉”之計。
PCPOP建議:
如果您是一般的用戶,可以說沒有升級這款驅(qū)動的意義,因為對于性能這款驅(qū)動并沒有很明顯的提高,即使是提到最大的Doom3也幾乎讓人察覺不到。
如果您是一個游戲玩家,不妨換這版驅(qū)動試試,因為在催化劑Control Center方面,ATI還是做了不少的改進(jìn)的,另外對幾款游戲的兼容性的改進(jìn)也是十分有必要的。
