Yes and again, 4.5 VRQ test patch has been updated, by adding one new commit to the -test branch after many tries to improve the interactivity based on current -test code changes.
In my test environment, with this new commit, there is no frame drop playing h264 video while 300% BATCH/NORMAL/IDLE workload in the background. Feel free to have a try and your feedback will be welcome. Next update would be happen in 4.6, :)
PS, I have forced updated the git branch, so please re-fetch them from git.
