Mantle Feedback/Bugs

chief barker · 2 Feb 2014 at 14:59

Am I the only one getting crashes with 7970/7970 crossfire?

Matt you couldn't tweet AMD about the issue please mate.

Jasonst888 · 2 Feb 2014 at 15:00

I gain about 10fps on bf4 and the graphs are a lot smoother. One issue is a giant CPU spike every now and then. Causes a miny stutter in game which is normally so small as to be no issue but i have had one instance of a freeze that almost convinced me the game had broken then it came back.

Have an i5 2500k, 290x

the crashes I was getting in Mantle were resolved by disabling crossfire.

I switched server, and it was fine. I then went back to that server and it was broken again. Odd!

There are reports of sound issues in maps apart from Conquest.

P.S gone back to DX, game seems better without Mantle.

Just to remind people.. Mantle is not actually working with 7000 series cards in battlefield yet.. so the gains your seeing there are most likely just driver improvements no?

I saw a big increase going to these new drivers in BF on my 7990 but im pretty sure thats only the Driver just being better since mantle isnt supported yet in BF on my 7990.

Also Crossfire doesn't work yet in Star Swarm so all your seeing there are single card results.

When I tried to deploy to a tank, bf4.exe has crashed so they need to fix this bug, LtMatt did you report this too?

Also for StarSwarm, I realized that used VRam size increased by 61.2% by looking at gpu-z, I will try BF4 next but can you also take a look at Dx vs Mantle VRam size?

There is no way I can get the new driver to worked, even trying to run Starswarm with Mantle Crashes. Done driver sweep and reinstall multiple times, out of ideas now.

Remember Ultra terrain detail was actually medium terrain detail?

Was that ever fixed Matt?

LtMatt said:
I believe it was.

It was never fixed, retested Jan 30th after patch.

Am seeing gains in Mantle with BF4 on my system. The frame rate is much higher and less drops.

Besty · 2 Feb 2014 at 15:08

Have created a CPU limited scenario using just 2 CPU cores on paracel storm, cannot see a difference in frame rates between Mantle and DX11. Conclusion is that yes you can switch mantle on for the 7970/7990/280x series of cards, just don't expect to see any difference yet.

Do you have a secondary graphic card like an onboard intel HD chip in your system? If so I have read on some forums that disabling it resolved people crashing problems with Mantle.

I had the same problem, fixed it by disabling the intel onboard Gpu in device manager.

Had a few issues with BF4 crashing after a few seconds but I rebooted and it was all fine after that

I am too...But is that just a driver improvement? AMD have stated that its not implemented yet on the 7000 series...maybe it is.. i don't know.
Im just going by what AMD have said.

Hi, nope no integrated graphics card, have an AMD FX 8120.
Been waiting all weekend and now this.

So what Ultra terrain detail is still actually medium terrain detail? What do we have to do to get Ultra terrain detail? Can you prove the continuation of this problem with ss?

No because if I was just using DirectX and only seeing boost in that api then I would say yeah. But I getting better performance when running Mantle so therefore it sure is working on 7000 series.

I'm getting constant Accessing to the Drive with Mantle, its causing stuttering.

I don't know why it would be accessing the drive and i don't understand how that causes stuttering as i have an SSD.

Dirkscooby · 2 Feb 2014 at 15:16

I'm getting crashes too using 290x in crossfire. No intel hd in device manager.

I'm getting the same mate, seems like my HDD starts thrashing then it crashes 'Bf4 has stopped working'

Memory leak?

so empty server screenshots to show my cpu bottleneck even on an empty 64 man server. I cant figure out how to screenshot in mantle so its taken with phone.
Mantle usage graph is also much smoother. I have briefly played full 64 man server but will further test it this evening much smoother though and minimums seem to stay above 60.
this is just a base test so dont respond with " but its an empty server"

Added fullscreen images,
going to try stand in the same spot on a full server lol
