Happens with other titles I've tried as well (wii&GC) but seems to be the worst in Sonic Heroes.
In other titles they get frame dips/stutters here and there that you don't experience in the stable build so I just usually just use stable despite the obvious visual errors that are only fixed in the dev build for a few games, but nothing like what happens Sonic Heroes.
In just the main menu you get stutters when selecting options and the moment you get to live gameplay where you're controlling it becomes non stop stuttering, visual and audio (milliseconds inbetween stutters). Completely unplayable.
At first I thought maybe it's the setting that fixes the graphical glitches causing the problem (the borderline makes the game unplayable graphical glitches) so I turned Vertex Rounding Hack off, restarted the emulation and nope, still stuttering and now it looks as bad as the stable build, but running horribly.
I figured maybe I have some setting different than in the stable build? Nope everything still sitting at the default settings.
So I don't know what is causing the issue, but it's a serious one, and I guess the mild stutters I wrote off in other titles as maybe being due to graphical fixes is more major than I thought, which warranted actually making a account to report the issue.
My specs are a 8350, 16 gb of ram and a r7 360 GPU, not amazing but considering everything runs perfectly smooth in the stable build with 8x MSAA and AF at 16x, I wouldn't think any tweaks in the dev build to fix graphical errors would cause much performance loss.
