As you can see using Mantle there is a major issue with overlapping images, almost like a mirror reflection problem, and it happens all the time, however if you switch to low graphics settings or medium sometimes it can go away. Using DX11 there is NO such problem. This is clearly a problem with Mantle and I've suffered with it for over a year. What is it? I'm using an MSI R9 290 Gaming card, but the same issue exists on my wifes PC with an R9 270X, so the problem lies with Mantle. It's happened throughout all drivers/beta/official too. Surely others have had this? Or maybe they are playing small TD maps and don't notice it.

 

Recorded at 1440p resolution and 30fps due to youtube maximum limit of 30fps at 1440p and higher resolutions. Re-encoded at 120,000 kbps x264. I have merged 2 separate files together into the one video. Before I switch to DX11 I obviously quit the game entirely and re-load the game.

 

Playing small scale maps you cant see or at-least don't have time to notice the problem as there is no massive distances to see like on conquest/large. It cant just be me having the issue with Mantle API.

 

DX11 maxes out at 2.9 - 3.2GBish Vram with these settings, Mantle maxes out at 3.2 - 3.5GB usually. Textures and distant objects are shown faster using Mantle and a 10% performance increase, but there is clearly a problem with either Mantle API or BF4 use of it. Tried searching for things like Mantle graphics glitches and other lines but nothing like it came up.

 

Selecting High/medium/low presets this problem doesn't happen, but selecting ultra it does. Even selecting custom and then putting settings to same as what high preset gives triggers the problem. What is it? Also switching to lower resolutions still shows it. There is obviously something triggering it through ultra or custom presets.

 

This EXACT problem happens with my wifes PC which is almost identical to mine except 1080p and a 270X.

Where exactly does it occur? Maybe I just am looking in the wrong spot, but I don't see it.

 

It could be a texture issue that Mantle can't handle properly. If it only occurs when using Mantle and not DX, would make me think along those lines.

Look to the area where the aerial towers are which is what I'm looking at with the chopper, look for them weird transparent glossy lines smearing over the image or replacing it wrongly. Do you not see it?

 

Anyway, iv'e went through the graphic options 1 by 1 and found the culprit!
 
MSAA x2 or x4 activates this problem! Iv'e reported it back to AMD on facebook and on EA. Dice better credit me for the heads up... :P

Ive had weird effects like that before with anti aliasing with older DX graphics cards. I'm not sure what I would call that, it's just a "texture that gets all weird" is the technical term I believe.
