Submission + - LibreOffice 4.2 with GPU mantle support is out (libreoffice.org) 4
Also of particular interest is AMD/ATI is expecting to finally release Mantle in the next coming hours for games like Battlefield 4. Surprisingly LibreOffice also supports mantle as well according to the release notes. However you will need the 14.1 driver which is being compiled and uploaded at the time of this writing to utilize this feature. Mantle will accelerate lower end cpus by up to 300% in some tasks while having modest improvements for those with more recent powerful CPUs. A real niceties for those like myself on AMD phenom II's with the later 7000 series cards.
The only issue (some on slashdot may say benefit ) is the lack of a ribbon UI. However, for recent articles about governments considering openoffice this release addresses shortcomings with the new active directory and GPO support.
