Guitar Hero 3 randomly slows down during songs
0%
Description
Game Name?
Guitar Hero 3
Game ID?
RGHE52
What's the problem? Describe what went wrong in few words.
Sometimes the framerate randomly drops by as much as 50% during songs, which makes it very hard to play.
What did you expect to happen instead?
I expect it to not slow down.
What steps will reproduce the problem?
- Turn on the game
- Play a song (it happened to me on both welcome to the jungle and paint it black, I didn't try any others)
Dolphin 3.5 and 3.5-367 are old versions of Dolphin that have
known issues and bugs, so don't report issues about them and test the
latest Dolphin version first.
Which versions of Dolphin did you test on?
4.0-3917
Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?
I don't know, and I'm not at my desktop at the moment, so I can't try it.
What are your PC specifications? (including, but not limited to: Operating
System, CPU and GPU)
Windows 8.1
i5 4690k @ 4.5ghz
gtx 780 @ 1100mhz
Is there any other relevant information? (e.g. logs, screenshots,
configuration files)
Not that I can think of.

We normally don't accept performance bug reports unless they're a regression or there is a particular problem in the emulator.
Regardless, try turning off vsync in the driver settings and Dolphin's Graphics Configuration and seeing if that helps
If not, please find out if this is a regression or not, and if you can narrow down when the behavior changed, someone will look at it.

Okay, I'll do that when I get back to my desktop, and then I'll try earlier stable/development versions if it doesn't help. I'll let you know what happens.

Vsync doesn't appear to have been on. I tried some earlier versions, and they don't work much better, so I guess it's not a regression.

So, it's very possible that a few things are happening.
1: The songs are just slow, a graphical feature in them is very slow. Maybe try checking disable EFB Access to CPU?
2: Something in the JIT/Interpreter is extremely slow?
3: The game is just demanding/uses a feature that we can't emulate well.
Maybe someone with a profiler can check it out?

- I tried disabling efb copy, and that didn't seem to help much if at all, plus it caused big black boxes to cover parts the screen occasionally.
2 and 3. Guitar hero Metallica runs perfectly, and I would think that it should be equally or more demanding, but I don't know.

Have you tried the GPU part of the Laptop Performance Guide? This might just be GPU throttling bullshit as usual. https://forums.dolphin-emu.org/Thread-unofficial-laptop-performance-guide

No, that's not it. It's a desktop, and it only uses the gtx 780.

Is there some kind of hack that would prevent dolphin from rendering the animation of the stage and band in the background, and only do the notes? That might be worth a shot.

The thing that bothers me is that this is a Core i5 4690K; so it shouldn't be slowing down... I've thought about this, and I'm marking it new for now. Try using the Emulated CPU CLock OVerride feature to see if that can fix it. Turn it up or down.

I have Guitar Hero III - Legends of Rock now and tested through the game. I'm unable to reproduce any kind of slowdown throughout the song. There are camera angles that are more demanding due to EFB Copies being used for effects, but that would come down to a CPU performance issues.
I'd like to make sure I have the right version of the game before proceeding forward and doing more research though.

No response plus certain camera angles use EFB Copies to RAM for effects. It's just the game being more demanding at points.
