The reduction in working set has a substantial improvement on system performan= ce. However, this has been demonstrate to be buggy on older hardw= are (845-865 and 915-945, but ok on PineView and later) so on tho= se chipsets defaults to off. Default: Enabled for G33 (includes PineView), and later, class machines. Should be decided by your GPU, but might make sure. --=20 You are receiving this mail because: You are the assignee for the bug.=
