In this series we’ll be looking at the benefits of AMD’s Mantle API over Microsoft’s DirectX 11.
This is a five part series; in part 1 we’ll be looking at the performance of AMD’s flagship single GPU the Radeon R9 290X.
Clearly Mantle offers current Radeon R9 290X owners an easy way to boost the performance of their hardware for free. That’s good news for those users that purchased their hardware with the belief that Mantle enabled games would eventually come this far into the mainstream. It’s also good news for AMD and its partners in the video game industry who have stacked up quite a bit of support for this API.
Highlights of AMD Catalyst 14.11.2 Windows Beta Driver Performance Improvements:
- Dragon Age: Inquisition performance optimizations
- Up to 5% performance increase over Catalyst™ 14.11.1 beta in single GPU scenarios with Anti-Aliasing enabled.
- Optimized AMD CrossFire™ profile
- Far Cry 4 performance optimizations
- Up to 50% performance increase over Catalyst™ 14.11.1 beta in single GPU scenarios with Anti-Aliasing enabled.
