Unwinder said:Happy New Year, guys! Beta 18 will be submitted to MSI today. Changes list includes:
• Added low-level I2C access driver for AMD Bonaire, Curacao and Hawaii graphics processors. Low-level I2C access driver provides much faster access to I2C bus than ineffective native AMD ADL I2C access interface and addresses issues with GPU clock throttling when enabling voltage monitoring on AMD RADEON R9 290 series graphics cards
• Improved AMD ADL access layer with Overdrive 6 support to provide compatibility with future AMD GPUs
• Regular and SE versions of MSI Afterburner are now merged into single installer. Added voltage control mode selection option to the “Compatibility properties” section in “General” tab. Now you can toggle between reference design, standard MSI and extended MSI voltage control modes
• Added “boost edition” / ”GHz edition” GPU type selection option for reference design AMD RADEON 7970 and AMD RADEON 7950 based graphics cards to “AMD compatibility properties” section in “General” tab
• Added GPU usage averaging algorithm for Overdrive 6 capable AMD GPUs. Now displayed GPU usage is being averaged by sliding window to smooth GPU usage artifacts occurring due to bug in AMD ADL API on AMD Sea Islands GPU family
• Added optional unified GPU usage monitoring path via D3DKMT performance counters. Power users may enable it via configuration file as a workaround to replace native vendor’s GPU usage monitoring if it is working improperly (e.g. broken GPU usage monitoring in AMD ADL API for AMD Sea Islands GPU family)
• Added “Use dedicated encoder server” option to “Videocapture” tab
• RivaTuner Statistics Server has been upgraded to version 6.0.0
I guess it will be launched publicly on 30-31 Dec or in the first days of 2014 if MSI are already on Holidays.
