So far, the only real world example of AMD’s new graphics API, Mantle, is some less-than-convincing performance in Battlefield 4. Now though, AMD have teamed up with Eidos and are set to release a new update to the latest Thief game, wrestling it away from the Microsoft clutches of DirectX and giving it some Mantle lovin'.

For the uninitiated Mantle is a rival graphics layer AMD have created to replace DirectX on their Graphics Core Next graphics cards. Its promise is of giving developers much closer access to the hardware they’re coding for, and reducing the processor overheads that have recently become synonymous with Microsoft’s API.

Unfortunately, while the Battlefield 4 update did offer some boosts, it did so at the cost of smooth performance. It raised the average frame rate on AMD cards, but slashed the minimum frame rate, leading to choppy war-based gaming.

While BF4 is the only real-world example of what Mantle can do so far, Oxide Games Nitrous Engine, shown via the Star Swarm demo, is a great indicator of what a game engine can do when it’s been created with Mantle in mind from the get-go.

Mantle performance in Star Swarm is far in advance of what the DirectX 11 version can do at the same system settings.
Fingers-crossed the new update to Thief leans more towards Star Swarm than Battlefield 4, and we start to see some serious improvements to Eidos’ game running on middle-order hardware.

Alongside the March 18th release of the Mantle update for Thief, AMD and Eidos are also releasing the first TrueAudio update for any game in the market. TrueAudio utilises the compute power in the graphics card to offload intensive audio effects from the CPU, which should give richer sounds to games.

In addition to making the game run quicker on AMD graphics cards with Mantle, it should also sound more realistic on them too. We'll see if this really is a game-changer tomorrow.

El 18 de marzo Eidos estaría agregando soporte Mantle para Thief, la nueva API de AMD, se espera que tenga mejores resultados que en Battlefield 4 que la diferencia no fue tan grande y se acerque mas a Star Swarm que tuvo una diferencia enorme de performance con respecto a DirectX 11 en el mismo hardware.

Mucho en la 290 y nada o casi nada en la 260 :/
Quizas dentro de un año o dos tenemos juegos optimizados al 100% para Mantle

Si, tipo la gracia sería que la mayor diferencia fuera en la gama media-baja, que es la ventaja supuestamente de utilizar una api de bajo nivel, pero bueno, como segundo juego que lo utiliza no estan tan mal los resultados, hay que seguir metiendole

Tambien hay que tener en cuenta que el juego no fue programado con Mantle en mente, el juego es DirectX y el soporte fue agregado en los drivers, probablemente esten transformando instrucciones a las equivalentes en Mantle onda como en el proyecto ToGL
