现在xmb占用64M内存，32M显存，并且始终独占第7个spu；
2.0开始，xmb占用32M内存，不在占用显存；而且不在独占第7个spu；

游戏中也可以呼出xmb:有些图标会出现，有些不出现了；
游戏中切换背景音乐的功能还是没有出现，哎；



A rumor is going about the Official EU Playstation forums about what firmware 2.0 will include.

"Presently, 64MB of XDR RAM, 32MB of GDDR3 VRAM, and the entire 7th SPU are always reserved for the XMB even during games. Firmware 2.0 will reduce the memory usage to 32MB of XDR and NO GDDR3. XMB will still run on the 7th SPU but the 7th SPU wont be reserved, other things can be run on the SPU besides the XMB."

Quote:
Firmware 2.0 will have in-game XMB.

Not all of the icons will be available on the XMB during a game.

Under 'Friends' there will be 'Block List', 'Add a Freind', 'Players Met', 'Message Box', and all of your friends. Your friends' avatars will not show in-game in order to conserve memory.

Under 'Network' there will be 'Download Management'.

Under 'Game' there will be the disk icon with the title under it. Seelecting this will prompt you for quitting the game.

The 'Video' column will not appear.

Under 'Music' there will be all of your sound files. You can play any of them and they will continue to play after you exit the in-game XMB. You will not be able to delete any of your songs in-game.

The 'Photo' column will not appear.

Under 'Setteings' there will be:

-'Game Settings' wich will include 'PS/PS2 Upscaler' settings and 'PS/PS2 Smoothing' settings.

-'System Settings' wich will include a new subsetting called 'Turn Off the System'.

-'Date and Time Settings' wich will include all the normal features.

-'Accessory Settings' wich will include all the normal features.

-'Display Settings' wich will include everything except 'Video Output Settings'.

-'Sound Settings' will unclude everything except 'Audio Output Settings'.

The 'Users' column will not appear.

从表面上看，2.0的升级不如1.9的华丽啊

赶快出啊...

真能把系统占用内存减肥就功德无量了

不错啊,这样内存大一些

真能减掉的话，某些厂商的借口就没有了。

是假滴~~

快出~

果然是 2.0 不错。

啥时候PS2游戏能支持硬盘啊...........

肯定不是真的，官方不可能给出这么深入的说明

如果XMB内存占用能降下去那就是最大的进步了

是真的就好了 看来2.0是最有意义的一次升级

个人觉得这是假的，不过削减OS在游戏中呼出的功能以减少os逗留内存消耗是势在必行的

如果真的是这样就牛B了
