      afaik there are 3 major graphics performance sinkholes.
      Range rings
      Reclaim labels (even when ctrl+shift is not pressed)
      and Level of details (visibility from zoomed out) for props\wrecks\decals on the map

      Is this a graph of ren thread CPU usage? how did you make such graph?

        This looks like a screen cap of MSI Afterburner set to capture data about the render thread. I've never used Afterburner for tracking just one thread.

          yes. it is afterburner. I reinstall graphics drivers and faf. The issue seems to have gone away, at least for a few games.
          I know it will come back when I start messing around with console commands again.

            This is extremely weird now. On ambush pass I see 100% cpu usage for ren thread. On craftius maximus I see about 30%. I am testing this back to back to back with consistency.

              fullscreen or windowed, do you limit fps? if not, ren thread will always be maxed

                @speed2 Although it is not always maxed, this is very useful so far. Thank you

                  @speed2 SC_frametimeclamp is set to 16 ms by default so limiting frame times didn't really make a difference. The issue is back once again

                    All fidelity settings on low low resolution, full screen.

                      There's nothing suspicious in the log. How much FPS do you get when it lags?
