cocos2d-x3.0开发游戏部分机型（显卡类型）闪退问题
拓展cocos2d-x3.0底层支持etc图片格式，把游戏中的模型使用etc格式的图片替换。
原先可以运行在联想（lenovo S880，显卡类型是PowerVP SGX 531）的机器上，但是换成etc图片之后进入游戏加载模型的时候就闪退了。
目前大部分其他机型上都没不存在这个问题，只有部分机器会闪退。初步判断有可能是显卡的问题，这个机器的显卡类型是PowerVR SGX 531。不知道各位大大有遇到相同或类似的问题没？

总结出可能导致游戏闪退的原因：
目前大部分其他机型上都没不存在这个问题，只有部分机器会闪退。初步判断有可能是显卡的问题，这个机器的显卡类型是PowerVR SGX 531。不知道各位大大有遇到相同或类似的问题没？

总结出可能导致游戏闪退的原因：
1.资源没有优化好，导致占用太多内存，被系统强制退出；
2.资源太大撑爆显存导致闪退；
3.图片太大（一些低端的机型显卡只支持最大图片大小是1024，那么这个时候就要注意了）；
4.图片不是2的幂次方，有些显卡是不支持非2的幂次方的图片（这次闪退的原因就是因为使用etc材质，显卡不支持etc图片非2的幂次方导致，但是支持png为非2的幂次方，所以找了好久才发现这个问题）。
