BF4 + Mantle, Performance?

Hellsrage · May 7, 2014

So I had not bothered with Mantle until CCC 14.4 dropped and my initial install saw no performance difference from DirectX 11 and Mantle, heck my FPS seemed to be 10-15 frames lower than normal. I was actually having a hard time keeping above 40FPS and on top of that I was getting weird stutters. I didn't know if this was the drivers or BF4 because honestly BF4 has so many issues it's hard to tell where the fault lies, either way a few days ago I did the standard uninstall and reinstall to see if maybe something in the command for the install went very wrong last time. Well. Something was definitely wrong on that first install because when I switched to mantle and put everything on Ultra this time around...oh boy did things start flying real fast.

I went from having a mix of mostly high and medium settings with 2xMSAA(@1080p) @40-60FPS using DirectX 11 to all Ultra with 2xMSAA(@1080p) @704w-80FPS with Mantle and the best part is the lowest I've seen so far is 60FPS. There are some issues in the menus where the FPS will tank down to 40 but never actually while playing, no idea what's causing that. Honestly I was not expecting that large of a performance boost, I just hoped I could play at mid/high settings without dipping below 60FPS. I am very surprised by the performance bump I've seen.

Has anyone else capable of using Mantle seen the same performance increase or better?

the fps dramatically increases, it triples for me but thats due to my inferior i3 bottlenecking everything, anyways the fps is higher however there are parts where it will stutter a lot and its hard to play with it like that, also it sometimes randomly freezes for a few seconds, it also becomes reactive, it never crashes on dx11 but it does on mantle.

Looks up some benchmarks. The performance increases are there, but it really depends on your setup.

Mantle has generally seen much more benefit from lower end hardware, you tend to see much lower performance increases from high end hardware. For example, my FX-8350 and R9 290X only get ~20% performance increase in BF4.
