    Performance improvements? All i see is juggling around algorithms that perform better in different scenarios.

        Many thanks, starting comparison tonight with Haswell and hope to get to 3.x or 3.0... Forgot exact timing with Haswell support off the top of my head. Didn't start with Skylake since can't get back too far, as what was it like Linux 4.3 when Skylake graphics were finally in good shape? Haswell had great support at launch-time so should be able to go back far. Hope to have tests done by Friday or Monday.

          Thanks! I think an even older chip from the sandy or ivy bridge generation would be even more interesting to see, since the driver support for those should be more mature in the older kernel releases, and you could go back even farther.
