The AMD Driver Thread

[LtMatt]

Agreed!

Matt, will have a quick go with single card in mantle in a bit. It's definitely when using mantle that I get the strange judder.

As mentioned before using ddu and reinstalling had cpu and gpu usage pretty smooth, but what I see on screen is not representative of that or the fps.

It's not microstutter...

Will use your car to see what mem usage like.

Apologies for possibly asking this twice, but you don't have Raptr/Gaming Evolved APP running in the background do you?

 

[LtMatt]

Though am in Bath at moment

Edit: maybe too much info

 

[LtMatt]

Giving it a go.

Shut down the browser 10 seconds after the map starts to load too. Can save a few hundred mb of video memory.

 

[LtMatt]

Can I move the text at all?

No.

 

[LtMatt]

Was fine with crossfire disabled.

Memory usage was around 4.4GB

Actually was surprised ho well one card ran everything at 4K

Interesting.

Can you try deleting the Mantle Cache files from the My Docs/BF4 Folder.

Re-enable Crossfire.

Load up BF4 and see how it goes again.

If problems persist, try tweaking the Frostbite Mantle frame pacing option. Default is 1, but you can try option 2 as well for smoother performance at the expense of lower fps.

Bring up the console and type RenderDevice.FramePacingMethod 2 and hit enter.

 

[LtMatt]

This is what it looks like when I get the lag.

Spoiler

Do you have anything else running that could be causing it? Can you check task manager to see if anything stands out when those spikes occur?

Was going to try.... But the game down now :/

Oh well, tomorrow I guess.

Is the game being updated?

 

[LtMatt]

Task manager is open but nothing is showing. If I play in DX it's a lot better.

Can you try clearing the cache folder and then resetting the video settings to default and trying again.

It's hard to diagnose the fault as you're within video memory tolerances.

Is the Origin overlay disabled?

 

[LtMatt]

Which cache?

My Docs, BF4, Mantle pipeline cache. It's unlikely to make a difference, but worth trying.

Does it occur with one card? If not then it could be something Dice will need to fix.

I don't see this when running 1/2/3/4 cards in Mantle, so it's hard to suggest solutions. The only difference is i have 8gb cards, but as you're within tolerances it's unlikely to be that.

 

[LtMatt]

There is no set date for the driver, but as soon as it's ready I'll post it here. Back when Omega was released we set a rough estimate of February as the next release.

 

[LtMatt]

Matt, did you get any feedback with regards to SWTOR and Crossfire?

Not yet, sorry.

@ AMDMatt

My fan issue has been sorted, took the 290 apart and the fan connection wasn't connected fully. Strange how it happened out of nowhere though.

Thanks for letting me know. That's one suggestion i did not think of.

 

[LtMatt]

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

Aida64 log: https://www.sendspace.com/file/x3q95k

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.

 

[LtMatt]

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!

 

[LtMatt]

Anything on Thief Mantle Crossfire issues, Matt?

http://forums.overclockers.co.uk/showpost.php?p=27581847&postcount=424

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.

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.

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?

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

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

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.

 

[LtMatt]

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.

 

[LtMatt]

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

Thanks, I will test this myself soon.

 

[LtMatt]

Thanks for the reply.
Do you know how to solve the map flickering in Dragon age Inquisition? I am getting loads of them...

I'm afraid i think that's an issue with the game itself rather than our drivers.

 

[LtMatt]

*nix ?
Upped the opengl perf ?

I keep hoping for a response to my Q at Matt

*cough* Hint *cough*

Sorry, missed your question.

I don't know of any specific performance improvements to OprnGL.

 

[LtMatt]

I wish AMD would include voltage control into CCC as I have a 7990 and always lower my voltage but would prefer not to have to install extra software like afterburner. Or can the card voltage be permanently lowered. Thanks

That's never going to happen officially, but there will always be third party tools for advanced users to tweak these things.

@AMDMatt

Will the next driver release contain the driver level frame rate limiter?
Are AMD aware of their higher overall CPU overhead in their drivers compared to Nvidia in DX11 titles?
Are the next drivers on schedule?
Does it also contain CFX profile for Dying Light?

Thank you.

1) I cannot comment on potential unannounced software features.

2) When the drivers are ready i will post about it here.

3) It's not for me to comment on our competitors drivers.

4) The next driver should have a Crossfire profile for Dying Light.
