I was sweeping the forum looking for a topic that gathers AMD user´s first impressions on Mantle API. Either it is hiding somewhere or it´s not yet created, but surely it should have a significant attention considering all the hype and promises made by it´s developers.

So, things we should consider are performance (FPS and gameplay smoothness) of Mantle API Vs DirectX 11. Make a reference of your setup: hardware description and setup (display resolution: 1 screen or 3 screen; refresh rates; operating system).

Core i7 4770k; 16 GB RAM; SSD; 7970 Xfire (R9280X); 5760x1080x60 Hz - 3x24´. OS - Windows 8.1

Mantle performance in Battlefield was very bad... much much worst than DirectX (a 40 to 60 FPS drop). In maps like Dawnbreaker I get 70-100 FPS running DX11 (Cat 13.12) and with Mantle, on Cat14.1 and 14.2, I get 20-35 FPS.

Some friends of mine running it on a single screen res were having better performance with Cat14.1 - they complaint about FPS drops after a few minutes of BF4 play. They are all using DX11 now...

Don't forget..the people who see the benefits more, are the people with middle-to-lower spec computers.

Yes, however Mantle was designed to be used with all GCN cards.  I myself have had a horrible experience with Mantle in BF4.  Though I must say I saw a 60% increase in performance over DX11 in the Star Swarm benchmark.  It's too early to tell where the blame lies.  It could be Dice's end or AMD's.  But I get severe stuttering and screen freezes when playing BF4 with Mantle.  DX11 with settings set to Ultra at 1080p single monitor and vsync I'm getting 60fps solid.

Had problems and poor performance initially but now have about a 10% plus improvement in framerate and smooth gameplay.   Crossfired on a higher specced system.  Unable to utilize Supersampling resolution "in game" with Mantle, however, but it works beautifully when engaged in CCC.

Exceeded my expectations!

Mantle is designed for consoles. They only made it available for PCs to make some hype. It will probably end up like PhysX. Some extra feature a lot of people cannot use because of lack of hardware support. I don't really think mantle performance matters, especially now at the start. DirectX works as it always used to. I don't think if someone has weak hardware, mantle will magically save them especially that it's not designed for old hardware (most of what can be called weak).

Perhaps there are limitations to future DirectX improvements and the "Law of Diminishing Returns" prompted designers to begin looking in new directions to improve tangible performance increases.

@ Sandcracka

The problem probably lies on DICE´s side then xD I noticed you are still running Win7... give 8.1 a try, you´ll be surprised...!

W9 will be even worse probably. Tablets won't just disappear. It makes more sense waiting for linux to get into gaming a little bit more.
