Dolphin, the GameCube and Wii emulator - Forums

I am trying to run the newest build of Dolphin as it is faster and fixes multiple graphical issues. I am running OGL on both the official as well as the dev build. Whenever I download a new dev build I rename the folder that gets created in "Documents" that way the emulator will create a new one with a clean config and shader cache. If I switch back to the official I simply delete the dev folder and rename the official back to the right name thus ensuring my config and shader cache are still intact. Here is the issue that has been ongoing.

I noticed when using the dev build the game will slowly degrade over 45 mins until either the emulator crashes or it gets stuck at 15 fps or lower. I have tested and verified that this only occurs with dev builds and not the official. I am using all default settings and I am only running at 720p no AA or AF or any post processing at all for that matter. I have checked my temps and they are well within the normal operating range. The computer is on max performance etc. GTX 1050ti core i5 6600 8GB. Has anyone seen this behavior? If so what can I do to correct it?

Thanks in advance.

P.S. This happens with both Cube and Wii, tested with Sunshine and Galaxy 2 and also MP4.

tl;dr- The dev builds slowly crash while the official runs fine.

The best way to help is to bisect. Try older dev builds until you find the one that caused this change. If you cut the range in half every step, it shouldn't take many tries.

Considering I don't run into this, I expect it to be something silly in Dolphin...

Slottedpig - with those specs you could easily run everything at 1080p or 1440p. Even if your display is limited to 720p, there are visual improvements resulting from the way the image is scaled.

It might be worth trying just to see if it has any effect on how fast the degradation occurs.

But my question is why would the official release not have the same behavior.  Im using the exact same settings and backend.  Did anything change with the audio codecs?  I noticed the audio is the first thing to start messing up before the video slows down.  Also I did start working backwards...I know that it happened before the 3700 builds.  Im currently on 1002 and going to see if it does it then.  Only issue is i cant get that build to display the FPS.  Is anyone else having this issue though?

Please see above video...this is what happens after about an hour.  This was on 4747 from a few hours ago.  I have started the bisection process but first I am going to try and turn the resolution up and see if by some chance that solves the problem.

Resolution increase from 720 to 1080 caused it degrade faster around 38 mins instead of about an hour.  Think something with the video backend?  Im using OGL but I know it does it with all the other ones as well as I tested it.  Thoughts?

If you clear EVERYTHING on the Shader Cache folder, what happens? It still slows down?

Yes sir....its weird...however, I realized my nvidia card was set to optimal power instead of max performance, I corrected that and the dev build still degrades even with a brand new config and shader folder.  The official runs like butter though.  Im starting to believe that whatever work was done on the gfx backend is causing it.  It fixed a bunch of graphical glitches but for me seems that it broke the emulator every 45 mins...was there any major work done on the sound codecs?

No one can help unless you bisect.
