Hi!

I just bought myself my new PC and as the title says, it has an A10-7700K and an R7 250 in Dual Graphics mode in it.

In Full Screen Mode no matter what resolution or refresh rate I run the games, I get screen tearing and stuttering all the time in the game and even it's menu's.

Windowed mode stops it, but I guess it stops the discrete card working with the APU too.

I have tried to do Dual Graphics with the monitor plugged into the graphics card and the motherboard, but I get the same results.

I've tried all kinds of drivers, from ASRock (motherboard) to MSI (discrete graphics card), with no success.

Keep crossfire disabled or lower in-game settings.

Do you have tearing and stutter in a stable framerate or do you get lots of fps spikes during gaming, especially in low settings ?

Do you get tear with v-sync on ?

Is it a specific game causing trouble ?

 

Monitor fps, cpu and gpu temps during gaming with a monitoring software like msi afterburner and make sure you can get a stable framerate and your laptop isn't overheating.

 

Make sure you have clean installed the latest drivers.

 

Test and post back.

Thanks.

Well. I bought an R7 250 and a high-end APU only for the Dual Graphics, so it would not be an option for me to simply disable it. I want to get it to work.

I have a constant framerate with no drops or spikes. I get fewer stutters in lower settings, but screen tearing still exist even with V-Sync On.

I've tried 3 different games: Sleeping Dogs, Dirt 2 and FarCry 3. The problems exist in all of them.

My temps are normal, or even lower than normal, and I've installed the latest drivers (WHQL).

I've managed to reduce the stutter by changing the monitor cable from analog to HDMI, but it didn't fully eliminate it.

 

Thanks for the reply!

Do you mind trying RadeonPro to force v-sync, triple buffering or, even better, force limit your framerate to your average fps that you get in-game ?

You may have to create a game profile for each game, but if you get it right, you won't regret it.

 

Just a suggestion that works for me as well.

Try it.

 

 

EDIT:    "Keep crossfire disabled or lower in-game settings."

yes, that was not helpful at all wasn't it now ?

Disabling Crossfire solves the problem but with it, I get 2x more fps

Yes i can relate to that mate.

I believe the drivers need more optimization for this kind of set-ups, but try my previous suggestion anyway.
