I get horrendous stuttering using Mantle in BF4. Works fine in DX11.

Sounds like the video memory over subscription issue. What settings are you using?

Will AMD launch some drivers such as nvidia. that let play 4k@60hz through hdmi 1.4 witch chroma 4:2:0?

I'm using the "Ultra" preset. Running it in DX11 works without any problems, always maintains 60FPS. Mantle however, stutters all over the place.

That'll be why then, using the ultra preset under Mantle uses more video memory than your graphics cards have available. Either use DX11, or lower AA to x2 or x0 and Mantle will not stutter.

Sounds like vram. I am pretty sure only the r9 290/x were able to run ultra as they have 4gb vram. You certainly have enough gpu power to run ultra but due to the frostbite engine on mantle the vram overhead is to much for the 3gb cards.

What i find odd is how it didn't stutter at all until about a month ago when DICE released an "update". So i hope the issue is fixed soon. Is it a memory leak or something?

Hi Matt, still got issues with Omegas and LOTR: SoM, to get CF working have to alt-tab out of the game, after a few hours of gaming, frame rate stutters then CTD.
Get a speech bubble saying VGA driver stopped responding, but has now recovered. It was OK with the 14.11.2 betas before. Also get a green flickering bar, sometimes during cut scenes!
Any news on VSR availability, for my GCN1.0 cards? Also CAP working for FC 4? Is there an official release date in place for the 380X, and will it be hybrid cooling only. Looking to move to one GPU!

Did you manage to get to the bottom of this Matt? Is he just behind the times? Or do we have even better performance to look forward to?

Yes i did Dave.

Actually a memory leak was found recently. It's a bit different from the well known Mantle (system memory) leak. This memory leak was in the base kernel mode display driver.

The developer was only tracking the memory allocations itself and noticed that they weren't being released properly. This case mainly happens in Multiplayer mode when changing maps so it's not as easily reproduced as the previous memory leak issue.

I would expect this to be fixed in a future driver update.

Cool cool

Well just spoke to AMD Roy via twitter and he asked me to send feedback to his email address about Raptr, Was very polite honest feedback, Basically yes it works but it needs to be on the same level as Shadowplay in the quality department and functionality, It was a rather lengthy email but that's the jist of it, I hope we see progress sooner rather than later

Raptr isn't really anything to do with AMD though. Any fixes or add-on come from the raptr team.
But am sure Roy can pass messages on.

Feels like its been centuries since we had a driver update lol

thebennyboy · 25 Jan 2015 at 22:43

Matt, it seems that the Crossfire profile on the 280X for Catzilla is not working. Had to force a custom profile to get it working.

ChrisD. · 25 Jan 2015 at 23:07

Hi Matt, any chance of some SWTOR attention?

There's been a memory leak like this on and off for the HD5 series since BF3. Was always fixed, then broken then fixed then broken etc. BF4 however never got fixed, although last time I played I didn't actually get the leak. Occurs only on map change though not all the time, always consumes ram like the cookie monster eats cookies, and of course since W8 does a hybrid shutdown you need to either do a full shutdown or a restart to clear it.
