AMD Wants Mantle In OpenGL

Tech Report says AMD's Richard Huddy has been talking Mantle, and OpenGL getting more like Mantle.

 

Huddy told us AMD has done a "great deal of work" with the Khronos Group, the stewards of the OpenGL spec, on OpenGL Next. AMD has given the organization unfettered access to Mantle and told them, in so many words, "This is how we do it. If you want to take the same approach, go ahead." Khronos is free to take as many pages as it wants out of the Mantle playbook, and AMD will impose no restrictions, nor will it charge any licensing fees.

AMD Mantle Linux Plans

PC World discusses AMD's plans for porting Mantle to Linux/SteamOS.

 

The company has received requests from developers to port Mantle to Linux, Huddy said. AMD over time will dedicate resources to the task, Huddy said. AMD hasn’t provided a time frame for when Mantle-based games for Linux will become available

AMD Catalyst 14.6 Beta Released

AMD has released Catalyst 14.6 beta.  Its mostly a Watchdogs release, but it also adds Mantle to Enduro mobile, and has some new features for Eyefinity.  Windows 8.0 users must upgrade to 8.1 for this and future Catalyst releases.

 

Feature Highlights of The AMD Catalyst™ 14.6 Beta Driver for Windows
Performance improvements
Watch Dogs performance improvements
AMD Radeon R9 290X - 1920x1080 4x MSAA – improves up to 25%
AMD Radeon R9290X - 2560x1600 4x MSAA – improves up to 28%
AMD Radeon R9290X CrossFire configuration (3840x2160 Ultra settings, MSAA = 4X) - 92% scaling
Murdered Soul Suspect performance improvements
AMD Radeon R9 290X – 2560x1600 4x MSAA – improves up to 16%
AMD Radeon R9290X CrossFire configuration (3840x2160 Ultra settings, MSAA = 4X) - 93% scaling
AMD Eyefinity enhancements:
Mixed Resolution Support
A new architecture providing brand new capabilities
Display groups can be created with monitors of different resolution (including difference sizes and shapes)
Users have a choice of how surface is created over the display group
Fill – legacy mode, best for identical monitors
Fit – create the Eyefinity surface using best available rectangular area with attached displays.
Expand – create a virtual Eyefinity surface using desktops as viewports onto the surface.
Eyefinity Display Alignment
Enables control over alignment between adjacent monitors
One-Click Setup
Driver detects layout of extended desktops
Can create Eyefinity display group using this layout in one click!
New user controls for video color and display settings
Greater control over Video Color Management:
Controls have been expanded from a single slider for controlling Boost and Hue to per color axis
Color depth control for Digital Flat Panels (available on supported HDMI and DP displays)
Allows users to select different color depths per resolution and display
AMD Mantle enhancements
Mantle now supports AMD Mobile products with Enduro technology
Battlefield 4: AMD Radeon HD 8970M (1366x768; high settings) – 21% gain
Thief: AMD Radeon HD 8970M (1920x1080; high settings) – 14% gain
Star Swarm: AMD Radeon HD 8970M (1920x1080; medium settings) – 274% gain
Enables support for Multi-GPU configurations with Thief (requires the latest Thief update)
AMD AM1 JPEG decoding acceleration
JPEG decoding acceleration was first enabled on the A10 APU Series in AMD Catalyst 14.1 beta, and has now been extended to the AMD AM1 Platform
Provides fast JPEG decompression
Provides Power Efficiency for JPEG decompression
Known Issues
Running Watch Dogs with a R9 280X CrossFire configuration may result in the application running in CrossFire software compositing mode
Enabling Temporal SMAA in the AMD Catalyst Control center under a CrossFire configuration when playing Watch Dogs will result in Flickering
AMD CrossFire configurations with Eyefinity enabled will see application stability with BattleField 4 or Thief when running Mantle
Catalyst Install Manager text is covered by Express/Custom radio button text
Express Uninstall does not remove C:\Program Files\(AMD or ATI) folder
