请教，内存都去哪了?

Cocos2d-x
#1

测试用代码如下：

require "Cocos2d"
require "Cocos2dConstants"
require "scheduler"

-- cclog
cclog = function(...)
    print(string.format(...))
end

-- for CCLuaEngine traceback
function __G__TRACKBACK__(msg)
    cclog("----------------------------------------")
    cclog("LUA ERROR: " .. tostring(msg) .. "\n")
    cclog(debug.traceback())
    cclog("----------------------------------------")
end

local plists = {
    "1.plist",
    "2.plist",
    "3.plist",
    "4.plist",
    "5.plist",
    "6.plist",
    "7.plist",
    "8.plist",
    "9.plist",
}

local frameCache = cc.SpriteFrameCache:getInstance()
local textureCache = cc.TextureCache:getInstance()
local scheduler = cc.Director:getInstance():getScheduler()

function load()
    local plistLoaded = 0
    local plistCount = #plists
    
    local sche
    sche = scheduler:scheduleScriptFunc(function()
        if plistLoaded < plistCount then
            plistLoaded = plistLoaded + 1
            frameCache:addSpriteFramesWithFile(plists)
            print("plistLoaded: ", plistLoaded)
        else
            frameCache:removeUnusedSpriteFrames()
            textureCache:removeAllTextures()
            scheduler:unscheduleScriptEntry(sche)
            
            print("........................................")
            print(cc.TextureCache:getInstance():getCachedTextureInfo())
            print("........................................")
        end
    end, 1, false)
end



local function main()
    local scene = cc.Scene:create()
    local layer = cc.Layer:create()
    cc.Director:getInstance():runWithScene(scene)

    load()
end

local status, msg = xpcall(main, __G__TRACKBACK__)
if not status then
    error(msg)
end





```


情况一：
执行如上代码，getCachedTextureInfo()输出情况为： TextureCache dumpDebugInfo: 0 textures, for 0 KB (0.00 MB)
任务管理器看内存使用情况：43 340 K
而且这里我在Texture2D::~Texture2D()中GL::deleteTexture(_name);处加断点发现确实执行了，纹理应该是释放了

情况二：
注释掉 load()，getCachedTextureInfo()输出情况为： TextureCache dumpDebugInfo: 0 textures, for 0 KB (0.00 MB)
任务管理器看内存使用情况：25 312 K

情况一中加载过纹理但是已经释放，为啥内存没有降下来？

怎么没人回答

#4

不要沉。。。

#5

用XCode看， 不要用windows 任务管理器

#6

windows下opengl的对纹理有自己的一套管理，并不跟着你的释放而释放。

3ks，我试试

3ks 我研究下
