I managed to limit the internal FPS of both GoW games to a fixed/stable 60 or 30 FPS (your choice) by inserting vblanks (1 for 60FPS and 2 for 30FPS).

At this point, it's clear why I said the option is not perfect.Īs alternative workarounds for 'better' performance, people use PPSSPP frameskip option, which is not a good idea in practice others just decrease the CPU speed in PPSSPP to ridiculous values (66, 33, even 15mhz ) to make the game 'playable', but the end result is just sad: a game randomly jumping anywhere from 10+ to 50+ FPS.īut… I didn't write this post as a complain, this is all about information and, of course, posting a solution.

If you want to check this by yourself, you can change the PSP CPU speed to some value where the game stays close to 60 FPS but not higher (50+FPS, according to the green FPS counter in PPSSPP) and you will see that the game feels a lot better than the 'fixed' 60 FPS you get with a higher CPU speed using normal settings. This is the forced frameskip I complained above. So for example, when you play the same scene at 65 vs 85 internal FPS, the games run a lot smoother at the lower speed. But there is more, while playing the game with the Prevent FPS option enabled, the higher the internal FPS (the one I found) value is over 60 FPS, the choppier the game runs. The internal FPS you get depends on the CPU speed you have configured in PPSSPP options when you booted the game. If you disable the Prevent FPS… option the game can run anywhere from 150+ FPS (ingame) to over 2000+ FPS!! (menus), which causes the bad performance I explained above if you enable the option, the game is still running at 90+ FPS (ingame) and 300+ FPS (menus), so it is still rendering more frames than it should.

Then I wrote a simple assembly code to show the internal FPS value instead of the ingame red orbs indicator, and while playing the game and monitoring the value I noticed some things: So while playing any GoW game on PPSSPP, I have always noticed that even when the emulator shows the game to be running at '60 FPS', the game feels like it's running at 40+ or 50+ FPS (like using some kind of forced frameskip), depending on what is happening in gameplay.Īfter some research about this, I found an address in RAM for both games where a continuously calculated internal FPS value gets stored as a float the addresses are (in CW Cheat format): I can easily tell the difference between different FPS in games, that is why I like so much to play them at 60FPS when possible. The problem is that this option is not perfect. This is why the option ' Prevent FPS from exceeding 60 (speeds up GoW)' was implemented by PPSSPP devs, a workaround to avoid rendering useless frames above 60 FPS, so we can get much better emulation performance.

PPSSPP runs PSP games with a lot better internal performance than a real PSP, even while using the same PSP CPU speed, so both GoW games are almost always running at higher than 60 FPS in PPSSPP even if you see its green FPS counter always showing 60 FPS as max (this is a PPSSPP limitation). GoW PSP games had been very CPU demanding with emulators since the beginning, and this behavior is the main culprit.

This is the same situation that happens when, for example, you play a PC game at 100FPS using a monitor with a refresh rate of 60 HZ: you will not see any visual difference (you may only get better input response) because the refresh rate is lower than your actual FPS and you will be just burning processing power. They always try to render the maximum number of frames possible, even when the game is already running at over 60 FPS.įor a real PSP this is not a problem, as the hardware can not actually reach 60FPS anywhere, but even if at some point it can do it, you wouldn't feel the extra frames because the PSP screen has a 60 HZ refresh rate. īoth God of War games are very special in how they run on a real PSP, and therefore on PPSSPP too. I have made some great performance improvements to God of War Chains of Olympus and Ghost of Sparta, something that was long needed for these games, but let's write some background info first, if you're interested to read them.
