    Not sure if LR Classic is using my GPU in Develop mode


      Just updated to Classic from LR 5.7 last week. In a few of the threads I've read here about GPU I see that the System Info indicates whether or not LR recognizes the GPU by stating:

      "Check OpenGL support: Passed"

      When I look at my System Info it states:

      ------------------------------------------------------------------------------------------ -------------------------------------------

      ------------------------------------------------------------------------------------------ -------------------------------------------------------------------------



      Task manager shows the GPU as not being worked when I am in Develop mode, not even when I use the Adjustment brush - even when many of the sliders are selected.

      My GPU drivers are up to date (even did a clean re-install of them v.18.1.1). Up to date LR and OS. My GPU has 4 GBs of RAM and OpenGL 4.5

      I use double monitors: BenQ SW2700 1440x2560 and a NEC 20WGMX2 1680x1050

      I've seen a few threads where it has been suggested to add the Config.lua file to the Lightroom presets root folder....would that be a solution? Or is there no problem here?
