Ppsspp Emulator has its interactive for emulating games, games peeps in the house will surely know what I mean by that statement. Each games in ppsspp has it own settings but I will teaching you on how to make it fast on PES 2013, 2014, 2015, 2016 but I only tested it on 2013.
PES 2013 seems slow on some phones with low RAM or some phones with large ram also. So go to each settings that i will drop below and set them up.
Rendering Mode - Non Buffered
Rendering Mipmapping - Checked
Hardware Transform - Checked
Software Skinning - Checked
Vertex Cache - Checked
Fastmemory - Checked
Multithreaded - Checked
I/0 on Thread - Checked
PSP CPU Clock Speed - 222Mhz (Important!!)
Dynarec - Checked
Enable debug Logging - Unchecked
However the fastness of the game depends on the RAM of Your Device. It works perfectly on Tecno F7 but lags on tecno M3 sometimes.
I hope is helpful? If you have any questions or don't know how to set this up kindly drop your requests at the comment box below.
