提速60%！《Doom3》終極Config優化

　　今年的超重量級第一人稱射擊游戲Doom 3正式版發售至今已經有3個多月了，PCPOP在第一時間奉獻的【雙豪華平臺17款顯卡，車輪大戰DOOM3】讓我們領略到了這款“硬件殺手”級游戲的恐怖，不少玩家都在感嘆：又要為了游戲而升級機器了。

　　記得當年Quake 3發售的時候，大家也曾經為其絢麗的效果而折服。但時至今日，電子競技玩家們已經用config文件把游戲效果修改的面目全非了：

 高畫質設置下的截圖

 經過“改造”之后的效果，注意右上角fps的對比

　　這樣做的目的一是提升游戲的幀速率，另外就是令對手的模型更加醒目，便于中遠距離的對抗。由于Doom 3目前也有加入電子競技項目的趨勢，因此config文件馬上要再次派上用場了。

　　和Quake 3類似，通過更改config文件降低畫質對于Doom 3中幀速率的提升非常明顯，接下來我們就一起通過4款玩家能夠接受的主流平臺進行測試，對比config修改前后的游戲幀速率。

　　在本次測試中Doom 3游戲分辨率統一使用640×480，config文件我們使用的是Rocketboy提供的優化配置，在【Q3ACN論壇】可以【下載】。在文章的后面還會有更加詳細的config文件參數說明，讓大家可以打造適合自己的配置。另外，由于目前版本的Doom 3在游戲中有60fps的幀速率上限，因此如果測試成績達到70-80fps的話說明完全能夠達到連線對戰的基本要求了。<

◎ 測試平臺

◎ 測試成績

　　通過測試我們看到，經過config調整之后幀速率提高了60％之多，幾乎快要達到60fps的上限了。可以想象如果我們對CPU或顯卡稍加超頻的話，“一步登天”應該是輕而易舉的事情。<

◎ 測試平臺

◎ 測試成績

　　在賽揚D平臺上面，config文件對幀速率的提升也是很明顯的，將近50fps的速度已經令我們能夠流暢運行游戲了。<

◎ 測試平臺

◎ 測試成績

　　P4平臺經過config修改之后也達到了80fps以上的幀速率，相信在對戰游戲中已經能夠滿足電子競技的要求了。<

◎ 測試平臺

◎ 測試成績

　　我想購買AthlonXP 2500+的玩家不少都要進行超頻，所以小編也干脆將CPU外頻調到了200MHz并把顯卡換成了Radeon 9800SE，結果幀速率達到了82.8fps，成為了今天測試中最具性價比的解決方案。<

　　config文件對于幀速率的提升作用這么大，它的工作原理又是怎樣的呢？下面小編就轉貼一篇Q3ACN論壇的精華帖，其中詳細說明了各個參數的作用，大家可以參照做出適合自己的配置文件，感謝【Punk[D.M]的翻譯】

image_anisotropy
Sets the maximum texture anisotropy if
available in the renderer. Set between 0 and 16 with the lower number being faster and the higher number being slower
設置各項異性紋理大小,取值在0-16之間,越小的數值越快.
image_filter

"GL_LINEAR_MIPMAP_LINEAR" (slower)
改變紋理映射的的過濾方式.
"GL_LINEAR_MIPMAP_NEAREST" (快)
"GL_LINEAR_MIPMAP_LINEAR" (慢)
這個和Q3里面的也是一樣的,但是感覺圖像變化沒有Q3那么明顯.
r_shadows
Enables or disables shadows, very high FPS gain with the drawback losing shadows generated by enemies and objects.
Set to 0(faster) or 1(slower)
開啟或者關閉陰影.0為關閉.可以大大提高速度但是DOOM3的氣氛也沒了...
r_useOptimizedShadows
Determines if static shadow volumes are used
Set to 1(faster) or 0(slower)
是否使用模板陰影.1為使用,可以提高速度.
r_useTurboShadow
Use a faster technique for generating dynamic shadows. This may cause loss of shadows on systems with older display drivers.
Set to 1(faster) or 0(slower)
使用更加快速的方法生成動態光影.但是在老的顯卡驅動上可能會大量丟失陰影.
1為開啟,提高速度.
r_useDepthBoundsTest
Specific to Nvidia hardware and may not be available in the current drivers. Enables UltraShadow II? depth bounds test feature for 5x00/6x00 cards.
Set to 1(faster) or 0(slower)
只有NVIDIA顯卡可以使用的參數,但是在當前驅動可能不能工作.在5X00/6X00這些顯卡上使用UltraShadow II技術.
1為使用,可以提高速度...未來...
r_Multisamples

image_roundDown
Controls how incorrectly sized textures are resized so they are close to a power of two. The default setting of 1 means that textures will be reduced in size possibly losing some detail, a setting of 0 means that textures will be increased in size.
Set to 1(resize down/faster) or 0(resize ip/slower)
控制對不正確的紋理是增大還是縮小來接近真實情況.默認選項1意味著減小紋理尺寸這樣可能會丟失細節.0就是增大圖像尺寸.

r_skipBump
Controls bump mapping, can be set so that Doom 3 uses a flat surface instead of bump maps

Uses black for specular lighting. Specular lighting adds texture to each object and adds additional lighting to their surface. Not worth the minor FPS gain in singleplayer
Set to 1(faster / uglier) or 0 (slower)

Set between 1 and 1.5, adjust r_lightscale for settings high than 1.5
這個和速度沒什么關系,是用來調整亮度的,不要設得太高,否則畫面看起來泛白.而且本身DOOM3這個游戲就是比較暗的.
取值1到1.5,大于1.5的值需要調整r_lightscale這個參數.
r_brightness
Does not affect FPS, helps with brightness.
Set between 1 and 2, if brightness is still a problem use r_gamma and/or r_lightscale
亮度調節,與速度沒關.
r_lightscale
Does not affect FPS, helps with brightness and raises the intensity of all colours.
Set between 2(default) and 4, only use when you feel r_gamma and r_brightness have not helped.

　　電子競技的玩家們為什么要想方設法提升幀速率？首先的目的自然是追求流暢，如果幀速率很低的話頭暈就在所難免了。然而還有一個原因就不是所有人都知道的了，那就是較高的幀速率能夠加快自己的移動速度。

　　這個觀點的解釋至今仍然存在一些爭議，小編的一個朋友閱讀過部分Quake 3的源代碼，其中有關人物移動的物理特性是這樣的，在單位時間內：

移動距離 = 每幀移動距離×幀數

　　由于Quake 3的物理引擎在計算每幀移動距離的時候存在某種誤差，導致在幀速率較低的情況下這個移動距離會偏小，表現出來的結果就是某些距離較遠的平臺怎么也跳不過去，而換成配置較高的機器之后就能成功。

 　　目前已知受到這種特性影響的游戲是Quake 3，雖然我們還不太清楚Doom 3中是否也存在這一現象，但Doom 3引擎中繼承了不少Quake 3中的特性，接下來將會加以說明。

　　說了半天，為什么移動速度如此重要？原來除了移動速度與幀速率有關這一現象外，Quake 3和Doom 3的引擎中還隱藏著一些非常Cool的特性，它們為游戲帶來了無窮的魅力。不相信？那就請繼續往下看……<

　　與CS不同，傳統FPS游戲中移動的重要性就在于搶奪地圖中的資源（武器，盔甲等等）。由于頂尖高手們的槍法不會相差太多，身體的“強壯程度”和手中的武器就成了對抗中勝負的關鍵。大家可以想想，兩個水平相當的選手相遇時，一個是生命值200＋盔甲200并擁有重型武器，令一個僅有100生命值且只有輕機槍，結果會是怎樣？

　　玩過Q3的朋友會驚喜的發現Doom 3中保留了螺旋跳和平移跳這兩種魅力無窮的移動方式（也有人認為平移跳的效果被削弱了），還沒有體驗過的朋友們下面就聽小編我來忽悠忽悠吧。

　　國內FPS玩家群體中，人數最多的恐怕要數CS的愛好者了，但是只鐘情CS的玩家一定體會不到Q3中那飛翔一般的移動方式。Q3有如此魅力主要得益于其引擎中的兩個特性：旋轉加速與累積加速（事實上前者在CS的引擎中也存在）。

　　下面小編就在一幅愛好者自制的Q3地圖：Drjump II Pro中簡要說明一下這兩種跳躍。這幅地圖的作者ID是愛雨（Loverains），這位溫和的東北人也是小編的朋友，小編正是在這幅地圖中學會了跳躍技巧。

 雙眼平視前方，預備——跳！

 暈，怎么差這么遠啊？

　　我們看到如果面向正前方奔跑之后起跳的話，在距離目的地很遠的地方就要掉落，但是如果在起跳的同時“甩”一下鼠標，就完全不同了：

 斜著前進，起跳瞬間鼠標往左甩

 過來了！此時頭已經面向左邊

　　螺旋跳的作用就是在第一跳的時候加速，后面如果想累積加速的話，就需要平移跳了，向左邊看的時候同時按左方向鍵，然后換往右邊看，同時按右方向鍵：

 小黑哥也沒我飛的遠！

　　我們看到第二個跳躍距離比第一個還要長不少，但是通過平移跳的累積加速就能輕松飛躍過去。

　　更具體的技巧小編就不班門弄斧了，感興趣的朋友們可以去【Q3ACN】看看，而且那里也有很多Doom 3相關的內容。<

　　最后我想說的是，今天的測試是在一種極端的條件下進行的，完全從追求幀速率的角度出發，如果您想要享受Doom 3的畫面的話就不要考慮這種做法了：

 Low Quality 640×480畫面截圖

 運行優化幀速率的config文件之后……

　　目前不少電子競技大賽都已經將Doom 3列入了比賽項目，在這種背景下，CPU/顯卡超頻、修改config都是配置不高的FPS玩家的必經之路。今天小編就是希望通過本篇文章，讓條件有限的朋友們也一樣能夠走入Doom 3的競技玩家行列，像Rocketboy一樣為中國的玩家爭光。<
