Sdar: I thought Mantle was only on AMD gpus for now, how could you compare it to OpenGL on nVidia GPUs? Even then, comparing APIs can be somewhat difficult if you aren't familiar with all the API specific optimizations.

Originally posted by dungeon View PostThey say several times they will not drop Catalyst driver for Linux because they have enterprise customers who use it, the same goes with the opensource driver, etc... so workers will have what to do: like supporting next generation hardware, Mantle maybe, etc. But OK i guess they can manage some devs time for the opensource driver if help is wanted/needed .
Ok, will not drop Catalyst but need freeze.

I remember there being talk of merging as much code as possible into the open source AMD driver and then anything else would be an optional closed-source module or something, any word on that? I'll try finding the article.

Mantle: It's faster than DX but only works on WINDOWS using AMD GCN hardware, is not open and even the documentation is under nda.
Opengl: Open, works on almost everything (Operating systems and hardware from desktop to mobile devices) is as fast as Mantle on Nvidia cards but too slow on Intel and AMD hardware.
Metal: Not enough information yet...
And sadly the more "reliable" api for AMD, Intel and Nvidia hardware is DirectX.
In all those implementation and APIs you mentioned something is fast, something is slow and something is unavailable (and there are bugs of course, in diferent implementation bugs are in different areas - that happens all the time) . Question about which most users care: is it supported, and if it is - is it smooth, and in the and is it working acceptible fast on my chip in scenario I need to use .Last edited by dungeon; 17 June 2014, 12:02 PM.

AMD is a big supporter and developer in Khronos Group. Their driver tries to closely follow the standard (although with not much success) and has promoted a lot of ARB extensions.
OpenGL 5 "Mantle profile" and that profile currently has some engines supporting it.

But it's a graphical api as dx is even if they don't support all the Operating systems or hardware.

Originally posted by sarmad View PostAre you making an informed comment here, or an educated guess? What Mantle profile are you talking about?
AMD will get this API tested with some games and could end being standardized as a new version of OpenGL once it's mature enough.

I am not a programmer, but Mr. "Moneyrich" is starting to sound pretty profane.
They are "implementations", per definition they will differ. Throw any other, especially closed source, API performing via, especially closed source, driver, on a, especially proprietary hardware - they will outcome with different quality.
I never heard AMD and Nvidia has joined effort to make their driver peform at equal speed, why the heck they even make hidden micro-optimizations/shortcuts.......
