Mantle Feedback/Bugs

Good read matt, after reading, it looks like the 7 series high vram usage is needing fixed by Dice on the engine side, as it's under the developers control.

Amd driving api's forward, looking forward to DX 12 (DXMantle:p) so that Nvidia users get a slice of the pie it's too good to keep to ourselves.

Annoying as Dice will probably just say tough and it is annoying the amount of VRAM usage, if they sorted it out and it dropped to DX values, I'd be able to enable 4xMSAA... at moment I'm maxing 3GB
 
So i had to reconfigure my joystick settings earlier as it seemed like my joystick bindings for jets were a little borked. Decided to just delete the settings folder and start it over.

Now i have it set up for jets tho it probably needs some tweaking but i thought i'd give Ultra a go for some silly reason. Anyway i did a full round on Shanghai with a full server and my VRAM only maxed to 2.8GB. Did Dice do something on their end or was it me deleting the settings file? Hmm :)

Either way i'll be running Ultra/4xMSAA for a while and see how it goes. May need to drop down to 2xMSAA just for that assured smoothness on multiplayer ;)

Edit.. Oh i also deleted the cache folder (Mantlepipeline stuff) in the BF4 folder under My Docs.

Mantle vram usage is getting lower with every patch. Seems like its a work in progress.
 
Let us know how it goes mybrains. I'm running a 290 now but if someone actually sort out VRAM on 7 series I still have 2 7970s on a shelf...

What I don't understand us why AMD have said in the past they need to optimise it though?
 
Mantle is total rubbish on 4 cards in BF4 I have just tried it in a couple of quick games with the CPU @4.0 and the cards at stock max settings @1600p. In one game I was averaging about 103 fps and in another about 88 fps, the mins and maxs did not move very much which was good though.

I then switched to DX11 using the same max settings and the CPU still @4.0, what a difference. The minimums were over 140fps, the average was about 170fps and the max I don't know because the frame counter spent a lot of time @200fps.

I suspect there is no 4 card Mantle support yet from what I have seen.

Kaap you're a noob. :p

Place this config file in your BF4 game.exe folder and test again.

http://www.sendspace.com/file/v5knn0

Mantles default frame pacing method sacrifices fps to keep frame times ridiculously consistent. This config uses a more balanced frame pacing method. (mantle has three different methods)

EDIT

If you're already using my config, then i apologise and i will speak to Thracks/Warsam and ask them why four card support is not working.

I am trying to make sense of the link, I am not sure what I am supposed to be downloading.

I have downloaded a file called

setup.exe.ffoodgs

Is this the right one ?

Jesus christ man, you're killing me. :p

I have no idea what file that is. Hold on ill use a different host. What you downloaded sounds like some ad thing from sendspace, so delete it. The file im sharing is a notepad User.cfg file.

Try this one.

Got it working, average fps in Mantle is now about the same as DX11. The difference is DX11 has higher and lower maxs and mins.

Mantle also seems to be very glitchy visually where as DX11 is glitch free, maybe this is something to do with Quadfire and Mantle.

You can always try disabling frame pacing altogether as well Kaap. Type RanderDevice.FramePacingMethod 0 into console. Or open that User.cfg file and change the 1 to a 0 and click save.

Keep an eye on the vram usage. It should display near the top of the screen when running Mantle. If you exceed the limit then that could explain dips in performance. If you're just running 1600P Ultra preset you should have plenty of vram.

For me on two card Mantle is different class compared to DX.
 
i've got a few glitches in mantle since the new drivers came out - orange girders, plus white screen crashes whilst using AB and Trixx. Anyone else have mantle issues in BF4 since the 14.4 drivers?
