The AMD Mantle Thread

[Skurge]

A nice 25% gain for 7970 there.

Also, those crossfire results mean I can Max the game out and get 120fps on my 950d. Totally worth it. When the fix crossfire that is.

Performance tools

To simplify measuring performance in the game we’ve added a new tool to the in-game console to record frame times for later analysis. Simply run “PerfOverlay.FrameFileLogEnable 1″ to start saving frame times and “PerfOverlay.FrameFileLogEnable 0″ to stop. The resulting .csv file will be located in Documents/Battlefield 4 which can be opened & graphed by Excel or other applications for viewing.Another in-game tool that is useful to use is “Render.DrawScreenInfo 1″ that will now show additional on-screen information about your CPU & GPU config, resolution and as well as if Mantle or DirectX 11 is used for rendering.

its only purpose being to try and sell AMD's low end CPUs. That strategy only works if everyone makes games for Mantle and that wont happen unless it has tangible benefits without having an AMD CPU.

Games providers are not interested in a tiny market that would
require 1000$+ systems to show their production in good light,
rather they are gearing toward the PC mass market to render
games attractive for the biggest part of consumers rather than
for the usual elite that hang on enthusiasts forums.

Whoah that is nothing short of groundbreaking (if true)! :wub:

Cf is not in this release. 7970 neither. gcn 1.0 missing on first release. And in general some memory and gpu optimizations still not made yet but comming next patches. Unfortunately it seems those msaa optimizations is missing also and have to wait. Quite beta but at least we have started.

Frame pacing (Frame latency)

The first being that AMD Catalyst 14.1 is the “phase 2” frame pacing driver they announced in October of last year. It enables frame pacing support in DX10 and DX11 applications on resolutions higher than 1600p with products that don’t feature AMDs XDMA technology. Example products include the HD 7000 Series, or the R9 280X and R9 270X GPU. This driver also helps improve the frame pacing in AMD Dual Graphics configurations, such as the new “Kaveri” APU paired with an AMD Radeon R7 250 GPU! We encourage you and your readers to test our initial implementation, and provide feedback as you’re able.

This thread is for discussing Mantle, not Catalyst driver issues. Stay on topic.

Intresting that it give more advantage CF.

up to 55% dam wow for CF.

Wow that is pretty awesome. Of course no one can test crossfire since the release doesn't have it but when it comes that is well worthwhile.

The driver has stuttering in crossfire when you use mantle according to AMD.

The release has XFire JUST for 290 290X 260X and 7790

Yes. I think we are actually lucky Johan and his guys do this for the higher end stuff. It shows they are gamers themselves and care for their goals. There is only minicule incentive for EA to do that eg cf optimizations as it doesnt sell a single game extra with all that high end optimization. Doing it better on kaveri is ofcource highly important because its a new market.

Just for older XFire with good ol' bridge, not with XDMA

Test case 3: High-end single-player with multiple GPUs

CPU: Intel Core i7-3970x Extreme, 12 logical cores @ 3.5 GHz
GPU: 2x AMD Radeon R9 290x 4 GB
Settings: 1080p ULTRA 4x MSAA
OS: Windows 8 64-bit
Level: South China Sea “Broken Flight Deck”
This single-player scene is heavy on both the CPU and GPU with lots of action going on. Test was done on the highest end Intel CPU on Windows 8, which is the fastest option before Mantle thanks to DirectX 11.1. Still this CPU is not fast enough to keep the 2 290x GPUs fed at 1080p on Ultra settings so we get a significant CPU performance bottleneck which results in major performance improvement when enabling Mantle.
Result: 12.76 ms/f -> = 8.23 ms/f = 55% faster

Test case 2: Standard 64-player multiplayer

CPU: AMD FX-8350, 8 cores @ 4 GHz
GPU: AMD Radeon 7970 3 GB (AMD will add support for the AMD Radeon™ HD 7970 in a later stage of Mantle’s release schedule, learn more)
Settings: 1080p ULTRA 1x MSAA
OS: Windows 8 64-bit
Level: Siege of Shanghai
Level was tested with 64 “pseudo players” that we have for our own internal testing that simulates heavy game workload that we have in multiplayer in order to get more deterministic results compared to full real multiplayer. 64 players on the large Battlefield levels is really demanding of the CPU so this test case is primarily CPU-bound.
Result: 18.87 ms/f -> 15.08 ms/f = 25.1% faster

55% increase with the best CPU and 290x crossfire? I'm amazed.

I imagine that crossfire 290X's are pretty CPU bound @ 1080. I'll be curious to see when review sites start doing tests at more realistic resolutions for a multi card setup like that.

Also, those crossfire results mean I can Max the game out and get 120fps on my 950d. Totally worth it. When the fix crossfire that is.

Looks that way from what they are saying. We are getting mixed reports though. Some are saying very little improvement and then these look really promising.

Cf is not in this release. 7970 neither. gcn 1.0 missing on first release. And in general some memory and gpu optimizations still not made yet but comming next patches. Unfortunately it seems those msaa optimizations is missing also and have to wait. Quite beta but at least we have started.

Not like AMD to jump the gun like this. /sarc

Until I see performance comparisons for NVidia, I'm skeptical..

AMD has had issues with CPU utilization in their drivers for some time now. I'm not sure if these issues are due to Direct 3D itself, or just AMD's inability to parallelize their drivers..

Later on today I may play through that exact area and see what kind of frame rate I'm getting so I can compare.. With V-sync off I've seen frame rates at nearly 200 FPS at times, and this is on custom ultra settings with 90 FOV, and 2x MSAA @ 1440p. Everything else is maxed..

 

[Jaydip]

So it is pretty worthless for all the guys with high end cpus, it can be interesting to APU buyers though.TBH I expected more from it, as a low level api, I am not impressed so far.But then the real question arises do people really buy APUs to play BF4? because if they have other hobbies as well it will fall short.

You keep repeating this mantra, yet the AMD cards are beating the competing NV cards at the price brackets such as 290 vs. 780. Do you have any proof that this so called "inability" is anything more than an Nv marketing bulletpoint? Who cares if it means nothing in the end?

Did you miss the crossfire results? It's very useful for the highest end too.

Where do they state this mantle version isn't for crossfire? I wonder why they publish the smoking crossfire results if it's not being released today?

 

[DarkKnightDude]

Up to 55% is hard to believe. That's crazy.

He is right. AMD has said that clearly that CF will have issues when using mantle and with Mantle CF can cause and instability and stuttering.
That why u never hype rumors,PR Slides and Rumors it will always let u down specially in case of AMD.

 

[desprado]

55% with lag,instability and stutter.AMD has said clearly.

CF is waste with Mantle at the moment.

That's what betas are for. To fix things if I recall.

 

[selni]

Doesn't that DX crossfire framerate seem crazy low? 78fps at 1080p in single player on two R290s?

 

[Spjut]

As I expected, really nice gains for the slower CPUs.
I don't get why some are surprised about the differences in Crossfire reportedly being big as well, Crossfire systems especially get alot of performance gains when overclocking the CPU

 

[Silverforce11]

Clearly its a rushed job, because a lack of proper CF for R290s is ridiculous when DX11 CF works flawlessly.

EA rushed DICE in releasing a bugged BF4 way too early, then AMD/EA rush DICE to release this Mantle patch way too early again.

 

[DarkKnightDude]

That's normal for that specific mission. Its the most demanding in the singleplayer.

Do you have the minutes from the meetings to know this?

Considering AMD hasn't released the driver yet, I'm not sure if it was AMD that pushed them.

I think as of now Xfire has issues with Mantle.
