***Official AMD Mantle Thread***

[tommybhoy]

Mantle is a low-level rendering API targeted at 3D video games.

Mantle was originally developed by AMD in cooperation with DICE starting in 2013.

Mantle was designed as an alternative to Direct3D and OpenGL, primarily for use on personal computers, although suitable hardware is fully available in the Wii U, PlayStation 4 and the Xbox One.

Gamebryo Engine(Fallout 3, Skyrim, Rift, Defense Grid: The Awakening)

Spoiler

We asked if AMD Mantle integration is on its way to Gamebryo or whether DX12 would be capable enough to provide low level access. “Our engineers have been testing Mantle. Mantle enables us to share many rendering code for Xbox One and PS4 and brings many benefits even on PC like explicit Multi-GPU management. Also Mantle exposes more low-level features than DX12 as extensions. Although we are going to inevitably support DX12 as well, Mantle is definitely the key technology that we’d like to adopt for consoles and high-end PCs.”

Unfortunately it isn't free, it's a capture/broadcast app, there is a trial available so you can try it out.

Steam Overlay now supported in Mantle games with the October 22 client update. Spread the word! Mantle support rolls on!

You need to enable Steam Beta:



Then select:

AfterBurner OSD- Unfortunately AfterBurner currently has no Mantle support, however you can install and run AfterBurner remote server and you can get almost all your OSD info displayed on your phone/tablet minus FPS and Vram usage.

DirectX vs Mantle performance comparison.

Some DirectX vs Mantle performance comparisons.

All Game Graphics settings and CPU / GPU clocks are what i run everyday.

A Side by Side video run of DirectX 11.1 vs Mantle on BF4 Shanghai, settings used: Ultra IQ with 2x MSAA, CPU FX-8350 @ 4.5Ghz, GPU: Powercolor PCS+ R9 290 @ 1125/1400.

Some parts in all BF4 Maps i find there are huge CPU bottleneck, i find that my FPS can be up and down erratically, Mantle keeps a far higher Minimum FPS resulting in a more consistent experience, i actually lock my Frame Rates to 90 FPS, it almost invariably sticks solid to exactly that.
The Shanghai main road is one of the worst for CPU Bottlenecking in DirectX.

I used Mirillis Action to record this as its the only thing that will record Mantle (Boarderless mode) unfortunately there is at least a 20% drop off in performance with it.


The actual performance difference in BF4 Shanghai, this benchmark uses the same methodology you see in the video.




Sniper Elite III

It doesn't make a huge difference, but again the frame rates are more consistent with higher Minimums, its a much smoother experience.



Thief

This uses Nvidia CPU PhysX, some parts can really tank the FPS in DirectX, its horrid, Mantle just powers through that and keeps nice high FPS.

I don't want to see any trolling, off topic rubbish, talk about how one card is hotter than the other etc etc.

I will just do what I said I would do here.

Any news on when DICE are going to get Mantle working for BF4? BF4 stutters like mad on my 7990 uses all my system ram and then crashes. As this was the launch game for Mantle and the reason I bought my 7990 add in it's the only game I play I'm not that impressed.

 

[shankly1985]

Nice thread
This a Good watch also. He explains about how multi-GPUs when running Mantle can each do there own work loads. I remember reading a while back, Mantle could combined the Vram on GPU's or you could have one GPU rendering a scene while another GPU is doing something more demanding.

Typical bloody Dice, the whole release of bf4 was a fiasco. took virtually a year to get it into proper playable state and they're still working on things that should have been fixed long ago. There was an update the other day saying they managed to replicate the memory leak and are working on a fix for it, many months after everyone was swinging from the rafters shouting about it.

Good idea to have it all under one thread imo. Surprised it hasn't been done already. Nice videos there, chaps.

With this in mind, could (in the future) mantle offer cross architecture crossfire support or running of a 'slave' card? As each card would do its own work perhaps the requirement for architecture specific multi card setups could be a thing of the past.

Think of it like running a dedicated physx card, only useful in more then a handful of situations.

You could say, run a 290 as a main rendering card with a 270x running as a slave to it.

Just a thought

Without sounding stupid, is Mantle working correctly at the moment? It seemed like in BF 4 using Mantle would make me stutter more than DX11 would. Also I couldn't monitor my temps/clock speeds with Mantle like I could in DX11 using MSI Afterburner, is there another way or different program I can use to do this?

I'd recommend using DirectX for now in Battlefield 4. Work is ongoing to address the memory leak issue with Mantle. Don't worry, I'm absolutely doing everything within my power to ensure this bug gets fixed.

No osd monitoring programs via Mantle yet, but you could use AB remote server on your phone/tablet for everything outwith fps/vram usage for info.

On that note it's possible to get an fps overlay working with Mantle games. D3DGear (free trial 15 days) currently has basic (fps counter only) on screen display support for Mantle. Check out my Sniper Elite V3 screenshot. (fps counter top left)

Yeah that's the thought. Very interesting idea when you start to think of the possibility of the things you could do.

I use hwinfo64 it runs in the background. Bf4 and mantle has worked very well for me.

True Audio is the one that I'm really interested in, but yes, mantle may be something I'll use as time goes on.
