RE: Guide:- Maximizing the performance of PPSSPP on your Android/Windows device.
As the Simulate Block Transfers option gets perfected (thanks [Unknown]!) and the number of games it works for grows daily, I am now inclined to recommend that users keep it enabled at all times (plus Buffered Rendering of course) in the newest dev versions, since the speed hit with it on is almost non-existant if a game doesn't use the feature at all.

This is in contrast to the Read Framebuffer to Memory modes which incur a massive global speed hit on all games regardless of whether games need it or not. These options are actually due for removal in the near feature once we've dealt with the remaining stragglers that still require those options, which have now been substituted with the performance friendly Simulate Block Transfers option.

See this github thread for more details.

TL;DR:- Keep Simulate Block Transfers enabled unless you're really hurting for speed (e.g. on a low end Android mobile device.)

EDIT:- Updated the guide to reflect the re-instatement of the "Disable Alpha Test" speedhack for PowerVR users.
