I am getting terrible stuttering in Thief using Mantle Crossfire. Here are some logs and a youtube vid showing the issue.

290X 4GB cards at 4K? You need to lower supersampling or use 8GB cards. The game needs more than 4gb at 4K maximum settings. Even using DirectX i get better minimums with the 8gb cards.

Am glad to see it not just me having issues with mantle and crossfire.

That quite different to my judder problem though.

No. I'm not using 290X's and i'm not using 4k

. I'm trying to get a benchmark for the Thief benchmarking thread, so far failing miserably.

Matt or others

Am I right in thinking a blank red screen of death is a memory issue? just had a few of them with my faithful 7970

Red screen usually = cpu vcore needs a bump, or two, or three. Can sometimes be Dram voltage/timings too. Not gpu!

Nutella33 · 4 Feb 2015 at 17:23

you piece of hot stuff you. I'll go fiddle with the vcore.

That 7970 needs to last until the 3xx comes out.

Anything on Thief Mantle Crossfire issues, Matt?

I'm not sure benny. Can you try altering the quality setting to see if it improves things?

@AMDMatt

Currently Far Cry 4 shows negative crossfire scaling only when entering some towns. These towns are often populated. This could be a factor. I've had various 290X CFX and 295x2 owners test this over at overclock.net. They all got the same result. SMAA also causes a screen burn effect after sleeping or looking at the world map. Have AMD been able to replicate and fix these issues? If yes, are these issues fixed under the new FC4 CFX profile?

I also spotted that Core #2 is pegged at 99 usage. Disabling and enabling that core via the affinity options in task manager resolves that, and boosts fps in these populated towns. Will the FC4 profile bring any efficiency improvements to the overhead and latency in this game?

1080p, Vsync OFF, Ultra, AFR Friendly, HBAO+, SMAA, God Rays Enhanced, Tree and Fur OFF, Soft Shadows OFF.

Thank you.

Hey Matt,

Somehow when I run the Thief benchmark with Mantle Crossfire, the game freezes and the driver crashes with the 'the display driver has stopped responding' error.

This was at 1080p.

Any ideas?

HI Matt,

I just tried to use Mantle in Dragon Age, however mantle causes very very long loading time. When I change it back to DX11 then everything is back to normal. And mantle stops msi afterburner showing the fps / other info as well.
Why is this happening?
Cheers

It's happening because it only works with Direct X. You need a FPS counter that is compatible with Mantle.

I'm afraid i don't know, but what i do know is we have a proper Crossfire profile and improved performance for this title in our next driver update. If these issues still occur after that, then please let me know and I'll pass it on.

Sounds like an unstable gpu overclock. Does it occur with both gpus at stock clocks?

Try my User.Cfg file from Battlefield 4. This should enable an on screen display for Mantle and allow monitoring of Fps and cpu+gpu frame times. Simply place it in the Dragon Age.exe folder.

I've noticed and reported the longer loading times too, but this may have something to do with all the caching that Mantle does before the map loads. This is not present in DX which is why it loads much quicker, but is not always so smooth.

Does anyone know if were going to see crossfire scaling for elite dangerous at 4k. would love these.

Yes we're going to add Crossfire support for this game, but as of yet i don't know which driver this will be in. As soon as that changes, I'll let you know.

Try turning SSAA down and you didn't say whether you are getting the same issue in DX11 at the same settings.

The benchmark thread wants those settings. I have the same issue ... crashes on start with Mantle, it's fine in DX11.

Works fine for me in Mantle

I even took a photo of my TV because the thread says you can't screenshot Mantle stuff, but that has changed now apparently...

Edit - That's the 2160p (4k) benchmark, by the way.
