Dolphin, the GameCube and Wii emulator - Forums

So, after I updated Dolphin to 3.0-362, I started to get a lot of errors like this on Dolphin's log, not a big issue, however, I noted that the emulation starts to get progressively slower, on my tests with Zelda Wind Waker, it was running constant and stable at 30 FPS when I booted the game on Dolphin and after around 20 minutes of playing, the max FPS that I get (in the same area that I was running at 30 FPS) was something like 13-15 FPS...

All my settings are the default, except audio backend (XAudio2), and some video settings (OpenMP Enabled, EFB Copies to Texture, fast mipmaps disabled)
< my computer specs are on my signature, issue occurring with 3.0-362 >

The errors that keep repeating forever on error log are these: (I would attach the log, but it is 50 MB in size)

Do you remember which revision the slowdown started in?

I'll try to discover the exact revision because I just updated from 3.0-232 to the latest, so I can't confirm it now...
______________________________________________

The last working revision is 3.0-319, any revision after the Gecko branch merge (3.0-323) have this issue. Also, this is occurring only with GC games, Wii and WiiWare games are working fine...

I took a look at the code changed in that revision and nothing should have changed unless "Enable Cheats" is used. Do you have cheats enabled?

Yes I have (now I'm asking me why? I didn't use cheats). Disabling "Enable Cheats" fix the issue (however it's a workaround)... Should I open an issue on Google Code?

Do you have logging enabled? If you turn off logging and enable cheats, does the game still progressively slow down?

Yes, but the slowdown reduces a bit (dropped only 5 FPS during 15 minutes of gameplay, with logging enabled it drop around 15-17 FPS)...
