Frameskipping logic (while trying to rectify black screen issue in few games) in recent builds screws many games very badly such as GTA VCS.

Are you saying that Frameskipping is basically useless in the latest builds no matter what the number? Hmm.. Let me try it out, and if it is, I'll alter my guide accordingly. EDIT:- Yup. I just tested Frameskipping in GTA VCS on my rig in sig and no matter what the setting, turning it on causes the game to just display a static image which only resolves itself once you turn off Frameskipping again. I may have to try out other games too, just to confirm that this is a global phenomenon. Tested with v0.8.1-1279-g2e6f1e0 EDIT2:- It seems that the phenomenon is limited to a number of games. Will publish results later.

RE: Guide:- Maximizing the performance of PPSSPP on your Android/Windows device.
A minor update to the Frameskipping situation.
Using the Fixed Speed Toggle (` key) to accelerate speed with Frameskipping in a quite a number of games is rather buggy at the moment. Normal Tab unthrottling is fine however when combined with Frameskipping. Testing is still in progress. Only use Frameskipping if you're struggling to even hit 60 VPS (100%) in games.

RE: Guide:- Maximizing the performance of PPSSPP on your Android/Windows device.
Here are the Frameskipping test results in over 26 different games that I've tabulated in an easy to read format.
Modes tested include:- BR ON and OFF, coupled with Fixed Speed Toggle and Standard modes. (Click to enlarge the table, it's a massive one) You can sort of notice a pattern here:- 0. Most games are fine with any level of frameskipping as long as you do not unthrottle the speed, and leave it at Standard (100%). 1. Most 30 FPS games now prefer a frameskip level of 4 or 8 when Buffered Rendering Mode is set and coupled with Fixed Speed Toggle. On the other hand, when Non Buffered Mode is set with Fixed Speed Toggle, they're pretty much okay with any Even (2,4,6,8) number of frameskipping. 2. 60 FPS games are a lot less fussy when it comes to frameskipping, even with the Fixed Speed Toggle enabled, with a few exceptions. In non buffered mode, any frameskip level is fine for any 60 FPS game. 3. Frameskipping is either a hit or miss proposition now. If it works, it works perfectly, with no flickering whatsoever. If it doesn't, one of the following scenarios will occur:- a. The screen turns black. b. The screen freezes. The game is still running in the background and you can still hear your character's movements. c. The chracter's movements becomes glitchy. All of the above scenarios can be resolved by turning off Frameskipping or moving to a number(s) the game prefers. (refer to my table above) For reference, Fixed Speed Toggle = Toggled Speed Limit:- 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 |

RE: Guide:- Maximizing the performance of PPSSPP on your Android/Windows device.
As of v0.8.1-1378-g664d74a, the frameskipping algorithm has been modified again by Henrik, so the advice given with regards to Frameskipping in my guide is now obsolete until I've performed some more additional testing on my own.
All users are advised to upgrade to the latest version to take advantage of this new Frameskipping method. http://buildbot.orphis.net/ppsspp/ 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 |

You mean games like GTA VCS and Crisis Core are fine with frameskipping now? (builtbot is down and isn't opening, gotta make a build myself! How's the progress of Multithreading up till now?) |

How's the progress of Multithreading up till now?) Still pretty experimental. Best effects are seen on users with already powerful CPUs like a Quad Core i5/i7 or better. There are net gains in Core 2 CPUs like mine but the effect is much smaller. Those CPUs probably don't even need Multithreaded in the first place since one i5/i7 CPU core can bulldoze through most games. I wonder what the effect is on a P4 with Hyperthreading?

Benchmarks showed that Pentium M @ 2.0 Ghz performs faster than P4 @ 3.0 Ghz with Hyperthreading. I bet Pentium M @ 2.0 Ghz (with 2 MB of L2 cache) will perform faster than P4 of @vsub_ |
