《鐵血聯(lián)盟：卷土重來》在安裝了最新版本v1.11的升級補(bǔ)丁后，在高難度的城市巷戰(zhàn)地圖下，會非常卡，已經(jīng)無法正常游戲了，要解決這個問題的話，不妨看看下面的分析與解決辦法吧。

藍(lán)曰補(bǔ)丁自帶三種難度的perception文件，用高難度，一路無事，但打到肯布亞（第一個大量建筑的地圖）時忽然非�？�。堅(jiān)持清掉肯布亞后一路正常直到圣莫娜時再次出現(xiàn)卡頓情況。如無意外，應(yīng)該有很多同學(xué)遭遇了這種問題�？�頓導(dǎo)致的情況是操作丟失而不是延遲，遂推測為運(yùn)算卡而不是畫面卡。于是開始排查問題。

對三種難度的補(bǔ)丁分項(xiàng)測試結(jié)果是敵人視野半徑過大導(dǎo)致卡頓  個人推測應(yīng)該是每一個敵人太大的視野范圍涉及到過多建筑物的障礙運(yùn)算時形成了太多冗余運(yùn)算,因?yàn)閷?shí)測中將地圖中的敵人清到只剩十來個時照卡不誤，顯然不會單純是CPU力不從心的問題。具體如下，摘出不同難度MOD文件以示：

HARD難度的敵人屬性比例：

MinHearDistance 100.0 // was 50.0
MaxHearDistance 450.0 // was 400.0
MinViewDistance 150.0 // was 50.0
MaxViewDistance 750.0 // was 400.0
MinHalfViewAngle 60.0 // was 20.0
MaxHalfViewAngle 180.0 // was 110.0
UnalertedViewDistanceFactor 0.75 // was 0.5
UnalertedViewAngleFactor 0.75 // was 0.5
SilencerFactor 0.085 // was 0.25
DefaultMercHalfViewAngle 140.0 // was 110.0, used for human non-guarding players. Always overrides perception calculated values to avoid hassle with detecting items etc.
DefaultMercViewDistanceFactor 0.6 // was 0.5, used for human non-guarding players
GuardingMercViewAngleFactor 0.7 // was 0.5, used for human guarding players
OccludedHearability 0.2 // was 1.0 (well okay it didn't exist at all)

Normal難度的敵人屬性比例：

MinHearDistance 55.0 // was 50.0
MaxHearDistance 300.0 // was 400.0
MinViewDistance 65.0 // was 50.0
MaxViewDistance 600.0 // was 400.0
MinHalfViewAngle 50.0 // was 20.0
MaxHalfViewAngle 120.0 // was 110.0
UnalertedViewDistanceFactor 0.45 // was 0.5
UnalertedViewAngleFactor 0.55 // was 0.5
SilencerFactor 0.125 // was 0.25
DefaultMercHalfViewAngle 130.0 // was 110.0, used for human non-guarding players. Always overrides perception calculated values to avoid hassle with detecting items etc.
DefaultMercViewDistanceFactor 0.6 // was 0.5, used for human non-guarding players
GuardingMercViewAngleFactor 0.7 // was 0.5, used for human guarding players
OccludedHearability 0.6 // was 1.0 (well okay it didn't exist at all)

可見hard難度的視野數(shù)據(jù)基本都增加了三分之一左右，而這體現(xiàn)在圓周面積上大了可遠(yuǎn)不止三分之一。文件里其它數(shù)據(jù)也都已對比排查過了，結(jié)論卡頓情況與視野直接相關(guān)且只與視野相關(guān)。以上述情況說，將視野改為Normal難度的數(shù)據(jù)，即游戲運(yùn)算速度恢復(fù)正常。

綜上，如果你也遭遇了巷戰(zhàn)場景卡吐血的情況，同時你的機(jī)器也不夠牛逼，你可能只有一個選擇：降低Hard難度下敵人的視野半徑數(shù)值。

補(bǔ)充：如果你是個純英文盲，甚至連字典都不會查，那么推薦你用上面摘出的Normal文件數(shù)據(jù)復(fù)制替換掉Hard文件里的相同部分。

降低難度雖然減少了游戲的樂趣，但總比卡得無法游戲要強(qiáng)，希望這些能解決你的問題喲。
