As you can see using Mantle there is a major issue with overlapping images, almost like a transparent glossy glass reflection problem, and it happens all the time and can become much worse looking, however if you switch to low/medium/high graphics settings it goes away. But as soon as you switch to ultra or custom (even if you change all to what high gives) triggers the display issue.
Using DX11 there is NO such problem. This is clearly a problem with Mantle of BF4 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 and this game. 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. However in regards to the 270x of my wifes PC she gets much higher fps using DX11 than Mantle with the same i7 4770k, motherboard etc etc.
It happens in every resolution, full screen, windowed, borderless etc. To easily see the problem go 25 seconds in to roughly 1min 23. I then end game and switch to DX11 as can be seen mid way through the video at 1:24 and repeat similar motion and NO graphical problem.
