AMD Aims To Give OpenGL A Big Boost, “API Won’t Be The Bottleneck”

lol flopper I really hope Mantle is as good as you've built your expectations for otherwise you're going to be extremely disappointed. I've learnt over the years it's best to be pessimistic about any companies initial claims. I remember before PhysX launched nvidia claimed it would change gaming, years later there's about 3 titles I've played where it's actually been beneficial to the experience.
 
OpenGL doesn't automatically mean it works on both nVidia and AMD hardware, due to the not so awesomeness of proprietary extensions :( over time these do tend to get added to the spec if they're good but it still leaves developers dealing with the specific hardware - this is one of the main reasons DX is so dominant.

Also OpenGL is not anywhere near 9* the performance of D3D - it's a significant amount faster in some situations (particularly when using hardware-specific code inevitably) but not any faster in others.

No and no.
Nvidia wont have anything close to Mantle likely ever.

John Carmack has already said that NVidia offers OpenGL extensions which are an equivalent to Mantle, if AMD can do the same then why not just do it from the beginning and get behind a truly open API (OpenGL)?

Adding Mantle to DirectX games like BF4 is just giving DirectX a lifeline at a time when it's going to come under severe assault by SteamOS/OpenGL. No games are going to be released Mantle only they will always have a backup DX support, perhaps there's more to AMD's lucrative Xbox One contract.

That's just more noise though until we actually really see proper and sustained results.

Click.
 
pcars are working closely with nvidia as well, some physx for certain aspects I think, they showed it as one of the games at the conference last week.
 
Don't forget these people know what they say gets plastered everywhere so nobody in the games industry whether they think it or not is going to bad mouth Mantle, not just yet lol.

Well, not unless you're someone like Carmack who practically breathes OGL

According to some sources they already do, AMD tout Mantle as being able to do "9X more draw calls per second than other APIs" and according to a number of devs Nvidia's latest OGL extensions have similar performance.




It isn't though, OGL is just as slow as D3D when its used as an afterthought, stuff built ground up for OGL is faster than D3D, and with hardware level extensions from AMD/Nvidia that will rise massively.




And support for every other O/S, greatly improved performance, etc, etc.




According to both Nvidia and AMD (plus lots of devs and people in the know) it will.

-----------------------

Just a thought, is it possible that this could be a case of one hand not knowing what the other is doing over at AMD?

This post is spot on. The key thing is that Open GL enables that higher level of performance over DX (potentially) when coded to do so, plug it in in a similiar manner as you would DX and you don't take advantage of that potential.

Mantle wasn't just about performance though it was just as much about making it easier for devs to tap into that performance especially while coding a game in a way that would be more portable between GCN on the desktop and consoles.
 
Let me get this right.

What people are thinking here is that Game developers would use OpenGL to improve performance on Windows in conjunction with or instead of Direct X and Mantle.
 
The way I see it is this:

NVidia have (by all reports) been working hard behind the scenes on their OpenGL Linux drivers in co-operation with Valve for SteamOS (with their own Mantle-like OGL extensions), so imagine a situation where SteamOS is released and games are 20-40% faster on SteamOS/Linux than their Windows/DirectX equivalents, there would be a mass exodus of gamers over to SteamOS/Linux and developers would be more likely to (finally) embrace OpenGL.

Perhaps it's just a coincidence that AMD (who are currently in bed with Microsoft on consoles and were up until recently strapped for cash) suddenly pop up out of nowhere with Mantle, which aims to do the same thing for Windows/DirectX based games.

AMD will presumably have to support Mantle-like OpenGL extensions if they wan't to perform well with SteamOS but given their past struggles with Linux/OpenGL what if they have decided to side with Microsoft, even if Mantle is a DirectX replacement the number of cards which support it are so few in number that any developer would have to stick with DirectX and only add Mantle as an extra.
