RE: Guide:- Maximizing the performance of PPSSPP on your Android/Windows device.
Updated the guide to include the newly introduced "Simulate Block Transfer" option from v0.9.8-788-g0b0e3ca onwards.

Intended to be used with normal Buffered Rendering, this unfinished feature was developed to be a lightweight alternative to the much more heavier "Read Framebuffers to Memory" modes in games that required them (e.g. Ys Seven), but still carries a noticeable performance impact in games when enabled.

Currently, the performance hierarchy for Rendering Modes is as follows, from fastest to slowest:-

1. Non Buffered Rendering*

2. Buffered Rendering*

3. Buffered Rendering with Simulate Block Transfer

4. Read Framebuffers to Memory (GPU)

5. Read Framebuffers to Memory (CPU)

(*1 and 2 are interchangeable depending on your device's native resolution and game tested. Non buffered rendering causes PPSSPP to use the native resolution of your screen if full screen is used, which may be slower than the 1x or 2x Rendering Resolution options that Buffered Rendering allows you to select. On Retina devices like Ipad 3, buffered rendering + 1x Rendering Resolution could definitely be faster than non buffered rendering.)

PPSSPP Modern Testbed:-
Intel Core i5 4690K @ 4.0 GHz
NVIDIA Geforce GTX 760 2GB GDDR5 VRAM @ 1138/6500 Mhz
16 GB DDR3 RAM @ 1600 MHz
Windows 7 x64 SP1

PPSSPP Ancient Testing Rig:-
Intel Core 2 Duo T9550 @ 2.8GHz
ATI Mobility Radeon 4670 1GB GDDR3 VRAM @ 843/882 MHz
8 GB DDR3 RAM @ 1066 MHz
Windows 7 x64 SP1
