Strange tearing issue

05-14-2010, 05:32 AM #1

Dolphin used to work perfectly fine for me, but all of a sudden I'm experiencing a strange issue with screen tearing. It is most visible when playing 60fps games like Metroid Prime. The tearing is almost permanently there, running in horizontal lines from the bottom of my screen to the top. I have no clue what could have caused this. I already tried different GPU driver versions and display settings, but to no avail. According to various benchmarks, my system performance is as good as ever.

Revision: any, even the older ones that definitely used to work.
Dolphin settings: Frame Limit Auto, VSync Off, Audio Throttle Off.
My system: i5 750 @4GHz, HD 5770, 4GB Ram.
Screen: 1080p TV connected via HDMI.

If I turn VSync on, the tearing is gone, but Metroid Prime will constantly drop to 45-50fps. I'm certain that I never used to have VSync turned on but there was never any of this horrible tearing and it was running at 60fps.

Anyone have a clue as to what might have happened? I would be very grateful for any tips.

Strange o.O, try to update drivers? Try everything that's related to drivers, maybe it helps Smile

Thanks! But I feel like I have tried everything already. I'm starting to think I was hallucinating when everything still worked.

In theory, there shouldn't be any tearing when Frame Limit is On and Dolphin is running at 100% speed, right?

Set framelimit off and Vsync on,Vsync does the same way like framelimit.

Not really, if I do that then it becomes super fast most of the time. The result looks similar to selecting the "Use FPS for Limiting" option next to Framelimit.

Use Framelimit - Auto so your game won't run faster than it's supposed to, and Vsync On to avoid tearing.

PS. Most of this settings have to be tweaked as a per game basis.

Download Rivatuner, and use D3D overrider that comes with it.
You can use this to enable triple buffering and v-sync in D3D games, never had a problem with tearing or mouse lag(almost) since i've used this.

I use D3D Overrider for most games, but it doesn't work with Dolphin. I guess it can't detect x64 applications. But you're right, I could give the x86 version of Dolphin a try.
