這里是V社給出的heapsize的注釋：Specifies the heapsize (in kilobyte) the game will use. This no longer exists on later version of? Source 2009 and? Source Multiplayer.?大概意思是指定游戲使用的堆大?。▎挝籯b）

剛剛測試了下，在游戲里用mem_dump看內(nèi)存分配情況。

heapsize在524288(1024 * 512) -?2097151(1024 * 1024 * 2 - 1)之間指令都能正常工作，

超過524288后除WaveData（似乎是音頻文件？）外其余幾項(xiàng)（模型文件等）都達(dá)到最大值，

在2097151下WaveData達(dá)到最大值(512.00 MB)。

heapsize達(dá)到2097152時(shí)游戲似乎無法正確調(diào)用內(nèi)存，開戰(zhàn)役也會(huì)直接閃退。

按照cv22642688里的方法設(shè)置（6000000，9000000，18000000等都試過），這幾個(gè)超過2097151的值都被截?cái)嗔耍透偷闹禌]有區(qū)別。

這樣看來2097151是配置允許的情況下，能設(shè)置的極限了。

不知道524288和2097151在實(shí)際游戲中有什么區(qū)別 XD

總結(jié)

設(shè)置為524288即可

heapsize上限為2097151，實(shí)際上設(shè)置524288分配給模型文件等的內(nèi)存已經(jīng)達(dá)到最大值，再往上加也只有增加音頻文件的緩存。當(dāng)然配置允許可以直接拉滿。

以下是各個(gè)參數(shù)的情況
