Thief: Mantle Performance
A few months ago AMD and Dice released a patch (and driver) which enabled the first real world example of Mantle. For those who haven’t heard Mantle is a platform which replaces DirectX when using AMD cards, allowing game developers better access to the GPU with the benefit, in many scenarios, of enhancing performance.
Today AMD and Square Enix release an updated driver and patch for Thief which adds support for Mantle. Here we take a quick look at some performance figures.
Our test rig for this quick test was based on an i7-4960X and XFX R9 290X Black Edition (with 16 GB DDR3-2133, 1TB SSD, ASRock X79 Motherboard, Corsair 1200w PSU and Windows 8.1)
The first thing that we need to note about our testing with Thief is that these results are based on a beta driver and beta build of the game. Additionally, performance testing of Thief is limited to the in-game benchmark rather than actual gameplay. Finally, with the Mantle patch installed of the three systems we tested, two had issues with the driver/game which could not be resolved before publishing. When we did get everything running the results at 4K were not great for Mantle but the 1920×1080 results were much more promising, giving us up to 6fps better performance on a 290X.
Also worth noting is that this patch for Thief, and the new AMD 14.3 beta driver, enable support for AMD TrueAudio which we will cover in a future article once we have had more time with the tech.
So, that is two games now on Mantle. What do we hope to see next? First we would like to see AMD work out a way to get Mantle support on an application such as FRAPS so we can fully test the tech in real world scenarios. Following that, it will be good to see an implementation at launch on a big title, rather than weeks (or months) after release.
In the mean time, here are AMDs own results from the Thief benchmark on a selection of processors and cards.
