optimize ram usage

[[Unknown]]

Masato: you can download Microsoft Visual Studio 2012 for Desktop (you'll probably also need Microsoft Visual C++ 2010 though.) This would allow you to compile. You'll also need to download and install the DirectX SDK. Luckily these things are all free.

With that, you can open the Windows/PPSSPP.sln file, and select "Debug" and run. It'll be a lot slower, and the log file will be huge, but it'll give a lot more information too.

xsacha: I don't know about all mobile devices, but anything running Linux and desktops should use memory committing. For example, even though we allocate 8MB for kernel ram (which is used only for savedata icons iirc), most of that is never used, and so it is never committed and takes nothing but address space (it is essentially free.) Depending on the tool, it won't even be counted (which is correct.)

Same with the jit cache, it's probably only reporting the committed pages.

Reading/writing memory still isn't free, though. For example, we could keep full doubles of all textures (to detect changes) - which would fix a bunch of texture bugs - but this would also make it a lot slower. More ram doesn't always equal more faster.
