Where are the old ppsspp dev builds

Just wanted to add a little something to the MT discussion that's most probably already covered elsewhere, and with much better detail and fluency by [Unknown] and the other devs.

To begin with, PPSSPP's gaming performance for your system is ultimately decided by two components, in the following order (simplified to a rather basic degree):-

1) CPU - Feeds intructions to the GPU

2) GPU - Produces the end result seen on your screen. Relies on the CPU for directions.

Here are situations where MT helps:-

1. User has a crap multicore CPU (e.g. Pentium D, Core 2, Atom etc) but combined with a supreme GPU (NVIDIA GTX 580,680, Titan etc) in comparison. As a result, the GPU is being severely underfed (low usage as seen in GPUz) as the CPU can't keep up with the GPU's demands for the emulator. MT will help out tremendously in this situation since more cores will feed the GPU better leading to a direct increase in overall performance. This is the best case scenario.

2. User has a "balanced" system but decides to run at lower rendering resolutions (1x), which effectively makes it a CPU-limited situation. MT will help, but to a lower extent, assuming again that GPU usage isn't maxed out.

Here are situations where MT will do next to nothing:-

1. User has a great multicore Intel CPU coupled with a mediocre Intel Integrated GPU (i5 combined with HD 3000 for example), and is running PPSSPP at a higher rendering resolution (e.g. 4x and above), effectively making it a GPU-limited situation (GPUz reports 100% GPU usage). No gains will be seen here.

2. User decides to jack up all emulator settings to maximum (10x Rendering Resolution, FXAA enabled, Texture Scaling set to 5x Bicubic etc.) on a great system (e.g. i7 2600k + NVIDIA Geforce GTX 680), making it another GPU-limited situation. No gains will be seen here.

The above scenarios all assume that you're unthrottling the speed/set Alternative Speed to Unlimited in PPSSPP. It's stupidly easy to get 100% speed for most games on the desktop if you're using one made in the past 5 years, so you won't see any performance changes if you don't uncap the Speed/Framerate.

TL; DR
Is your GPU satisfied by your multicore CPU and being fully utilized (100%) as a result?

Yes = No gains from MT.

No = Gains from MT.

As long as there is more headroom for the GPU, MT will help.
