Game or games this happens in

GTA VCS LCS

What area of the game / PPSSPP

The game doesn't run at 60 fps normally. Are you using some cheat to get to that framerate? The slowdowns may be related to that, rather than PPSSPP itself, and if so it may help to do stuff like increasing the CPU frequency on the System tab.

so that's the thing, I set an exorbitant frequency and it didn't help, it still seems to me that you need to work with something so that the game doesn't slip, even with skipping frames, the game farts sound at 60 fps. 30 fps is the last century

although gta 5 goes 60 fps at high settings and this is a 2006 game farts sound strange

@Gamer123dsg what CPU are you using? and did you use the 60 FPS cheat?

xeon x5450 but this game 2006 year and gta 5 hugh settings , but I will say that it used to be worse on this emulator, before the sound was very hoarse and now not so often

Both GTA games are capped at 30 FPS where the most PSP games also runs at 30 FPS.

Unfortunately your CPU is too old and weak single thread performance, A recent CPU is recommended for good single thread performance.

Gamer123dsg commented 1 year ago

most likely , it is not my processor that is weak , but the emulator itself , because gta 5 goes at high settings with 60 fps

hrydgard commented 1 year ago

The game is written to run at 30fps, and that's what the logic inside the game expects. Likely, your 60fps patch that you are using is missing something that needs to be changed, and it's thus a question of game logic, not performance.

60fps patches are not guaranteed to be perfect in any way.

Lol widescreenifx fixes 60 fps or cleo

Gamer123dsg commented 1 year ago

most likely , you did not make the game work with such fps , because there is no fart sound at 30

You seem to fundamentally misunderstand how an emulator works. We run games as-is, that were written for a soon 20-year old console (the PSP). If the game runs at 30fps (syncs to the display twice per frame) on the real hardware, it will also do so in PPSSPP. We don't always get the exact emulated performance right, but it's about being as close as possible to the real hardware, in order to ensure compatibility with the maximum number of PSP games.

Now, some people have made hacks that disable frame syncing and maybe change some parameter for the game to run at a framerate it was not designed for. These hacks are often incomplete and don't change everything that needs to be changed.

Thus, the problem is with the 60fps cheat/hack, not the emulator.
