If a picture is worth a thousand words and a video is worth ten thousand, a GE frame dump is worth a million words.

Tried to catch 3 times, the recording only started after the fps stabilized so I'm not download them. For the 4th try the debugger freezed at "Recording" now it's not connects.

What if you added this game id to ForceMax60FPS?

QrTa commented 2 years ago

@Gamemulatorer what is that? How can I add it?

Create compat.ini file in your psp/system folder. Screenshot_2022-09-16-22-31-00-82

Also on my phone :( Screenshot_2022-09-16-23-27-54-31

@Gamemulatorer I mean mine is running with full speed, but there are places where I stand and starts spinning I got these drops but only for a second or half. This is why I can't catch GE dump from the slowdown.

Both happens in OGl and VK backend? Are you using the 120hz screen refresh rate of your phone?

QrTa commented 2 years ago

Yep, OGLES and Vulkan. I'm using my screen on 60Hz.

What happen if you turn off hardware transform?

ghost commented 1 year ago

No feedback/outdated???

hrydgard commented 1 year ago

No, i think there is an actual issue in this game, timing maybe, that should be investigated

ghost commented 1 year ago

This is the same as https://github.com/hrydgard/ppsspp/issues/12313#issuecomment-903581961 I got stable fps if I overclock it.

Or this might be improve if ever sync to host is implemented https://github.com/hrydgard/ppsspp/issues/15081

unknownbrackets commented 1 year ago

An FPS drop to 50/60 can't even possibly be helped by that, no. That's a request to scale game speed to the ratio of your display speed (for example, if your display is 75 Hz, to run at 125% speed, or if your display is 59 Hz, run at 98% speed.)

In this case, the game is (sometimes) outputting less than 59.94 frames per second. Even if you fast-forwarded emulation constantly to 125% for a 75 Hz display, it would still be outputting 16% less frames than it should, so you'd still get a frame drop.

It would help if someone can check this on a real PSP, just so we're sure there aren't FPS drops in the game itself. It's probably some timing issue, though, I guess... usually we're faster than we should be, though.

@QrTa what if you set emulated psp cpu clock to 666mhz?

antipirgos commented 2 months ago

We need 30/60 fps cheat codes for this game its the only way to play normal.
