Last Updates: 2/1/2014
Article Number: NA
​B​​elow are the known issues AMD has found in the first Mantle-enabled Beta driver. We are providing this driver as is to highlight the potential of Mantle and are hard at work to further enhance the user experience.
Intermittent stuttering or stability issues may occur when utilizing Mantle with AMD CrossFire™ technology in BattleField 4™
Mantle performance for the AMD Radeon™ HD 7000/HD 8000 Series GPUs and AMD Radeon™ R9 280X and R9 270X GPUs will be optimized for BattleField 4™ in future AMD Catalyst™ releases. These products will see limited gains in BattleField 4™ and AMD is currently investigating optimizations for them.
Multi-GPU support under DirectX® and Mantle will be added to StarSwarm in a future application patch
Notebooks based on AMD Enduro or PowerXpress™ technologies are currently not supported by the Mantle codepath in Battlefield 4™
AMD Eyefinity configurations utilizing portrait display orientations are currently not supported by the Mantle codepath in Battlefield 4™
Graphics hardware in the AMD A10-7850K and A10-7700K may override the presence of a discrete GPU under the Mantle codepath in Battlefield 4™
AMD testing for the AMD Catalyst™ 14.1 Beta has been concentrated on the following products: AMD Radeon™ R9 290X, R9 290, R9 280, R9 270, R7 260X, R7 260, HD 7000 Series, HD 8000 Series, A10-7850K and A10-7700K. Future AMD Catalyst™ releases will include full test coverage for all AMD products supported by Mantle.​​

Useful In Game Commands To Monitor Performance

Bring up the console in game.

FPS Monitor type - PerfOverlay.DrawFps 1

Cpu+Gpu performance overlay type - PerfOverlay.DrawGraph 1

To take a screenshot type - Render.Screenshot

To enable a FPS log type at start of bench - PerfOverlay.FrameFileLogEnable 1

To stop FPS log at end of bench type - PerfOverlay.FrameFileLogEnable 0

A little tip. Whilst the level/map is loading you can type in PerfOverlay.FrameFileLogEnable 0 and press enter. Then when you need to start logging just bring up the console, press down arrow key on your keyboard or S and that last written command comes up. Saves you retyping it each time. Just change the 0 to 1 and hit enter to start recording.

 

[LtMatt]

Yes this is for posting of benchmarks and stuff only really. I will let people post them and then try and find some way of adding them coherently to the first two posts. Sorry for the late posting of the thread. I'm amazed no one else did it. I was away last night getting drunk round a friends, came home and went straight to best. Woke up this morning with the worst hangover ever, but seeing this has cured it somewhat. Now to install the drivers.

 

[LtMatt]

I must warn you, my crossfire setup was seeing constant up and down from 30 to 20, the perfoverlay graph looked like one solid line of green! Also, if you haven't already, disable the igpu in device manager, otherwise clicking options in bf4 crashes for some reason.

Installed with no issue so far, but ill keep my eyes peeled. Using the msi afterburner overlay causes the game to crash, so keep the overlay disabled/msi afterburner shut down for now.

What are you using to test/capture those stats?

Place this file in your Battlefield 4 main directory with the exe. This will put up render graphs and an fps counter in game. It will also output render times and fps details to My documents Battlefield 4 folder.

[LtMatt]

do we have a planned bench with BF4 i.e single player with x level or Mp with x map?

I will upload one for everyone to copy. I'm working on it now. Its a very consistent and easy to bench scene.

 

[LtMatt]

According to Johan Anderson Mantle makes no changes to image quality vs DX (pulled from his twitter) so if there is a change its a bug.

 

[LtMatt]

As per my post in the other thread been a few people claiming that BF4 using mantle is clipping the far plane when rendering (so ultra long range stuff isn't rendered) and covering it up with gradually increasing density fog upto the cut off hence the loss of contrast on distant objects - it should be pretty easy to prove or dissprove that with long range views in golmund though.

Sounds like FUD or more likely a bug with the game. Remember Ultra terrain detail was actually medium terrain detail? Anyway i tweeted a link to the url to johan and will see what he says.

 

[LtMatt]

People are starting to complain that the visual quality in mantle is not as good as DirectX but I won't say I told you so on the other thread that got archived now. Ohh well AMD ... and anyone that believes it's a bug needs an eye test it's clear from screenshots now appearing on the internet that AMD are using cheap tricks to raise the frame rate. So basically sacrifice DirectX high quality visuals for faster frame rates in Mantle.

Let's hope they fix it and not do what Nvidia did in the past with their driver settings to make it look like Nvidia cards were faster than AMD/ATI and the only reason they were faster was because they lowered visual quality to achieve the faster performance. One company is just as bad as the other really.

Please don't bring crap like that to this thread. Seen plenty of that in the now locked Mantle thread.

 

[LtMatt]

You can see a difference in the mountains to be fair. I'm edging towards this is a Dice bug, but i will notify AMD as well. Lighting definitely seems a bit different. I prefer the lighting on the Mantle API but the mountains are definitely a bit more blurry.

[LtMatt]

THat is some difference Weldon, impressive.

 

[LtMatt]

Fog is a bug

Edit
Nice hunting Matt

LT taking care of business since 1981.

 

[LtMatt]

Anyway my original post about the fog issue was to discuss the point. I hate it when trolls like tommy boy come in posting silly pictures derailing the thread. There is no need for it. Whether that was aimed at me or not it was totally uncalled for.

Relax man i don't think it was aimed at you. I know Tommy well and hes a sound bloke. Its hard not to think like that sometimes with some of the FUD that gets posted here. Nonetheless its sorted now as Johan has confirmed its a bug and won't affect performance. Good for everyone all round, cept the naysayers.

 

[LtMatt]

Anyone else getting CTD's? had a few now while playing.

How do i disable AB overlay?

Theres a bug that if you enter a tank and use the gunner seat you crash to desktop lol. Its a really bad bug. Hoping that one gets fixed asap.

It's hard not to have a man-crush on LtMatt

Lol, i wish you were female.

Was that ever fixed Matt?

I believe it was.

 

[LtMatt]

Nothing personal but I have a hard time taking his word for it that it doesn't affect performance :S (not even hating on AMD - the mess BF4 is in doesn't convince me they actually know what they are talking about).

Fair enough, time will tell Rroffles. I've faith in Johan. It would look foolish to lie over something like that.

All new is well forgotten old. History repeats itself. Hard to escape your true nature.
Two years back AMD there launching 7000s with very same image quality trade offs.
It' good they fixed it, like in 5 months.

I'm going to ask to get this post deleted. Really want to keep mud slinging out of this thread. It ruined the other Mantle thread.

 

[LtMatt]

I will add this to the OP to clear up some confusion. Read the known issues.

[LtMatt]

Hmm going to need a way to benchmark BF4 with Mantle but trusty fraps doesn't work with it.

 

[LtMatt]

Am sure the latest Patch added it's own Benchmark tool.

Oh yeah? I thought that was just render times?

 

[LtMatt]

Here Matt
-Added new “PerfOverlay.FrameFileLogEnable” command that records frame times on CPU & GPU and logs out to a .csv file

I need fps minimums and averages though Shanks.

 

[LtMatt]

A senior moderator at oc.net actually posted some crossfire 290 figures. Guess what? He overclocked his i7 6 core cpu as well. This ones for andybird/Kaap.





The bottleneck of DX11 API removed.

 

[LtMatt]

Rroffles this is how im picturing you right now.
