    Your issue and other problems with the Makefile (with suggested fix) have been reported already on github https://github.com/clbr/radeontop/pull/2

      Switching obj and LDFLAGS in the Makefile did the trick.
      Senk ju ferrie matsch.

      Great to see there is already a fix in the pipeline.

        But to get more accurate numbers, try "-t 1000" for example.
        I completely missed that parameter, thanks.

        Indeed, even increasing it slightly from 60 to 70 Hz results in a comparably steady state.
        Not sure if this can be generalized, but maybe it's not a good idea to poll registers with 60 Hz while
        your 3d app runs v-synched at 60 Hz also. Just an idea, where that "beating" might result from.

          0.5.3 tagged, with various build fixes and default ticks upped to 120. Thanks for the feedback!

            It would be nice to choose the graphic card.
            Are they the same model (pci id) or different models? Currently it just picks the first Radeon GPU it finds, I wonder what would be a good interface that would handle many cards with the same pci id.

              01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Barts XT [ATI Radeon HD 6800 Series]
              09:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV710 [Radeon HD 4550]

              I use the second one for displaying my desktop.

                OK, perhaps the first number (slot?) is the answer. I'll put it on my todo list.

                  Is all of this specific to radeon hardware?
                  It would be nice to get similar information from nouveau/intel drivers; merge it all into one tool and then we can call it "dritop"...

                      There's already a similar tool for intel, that's the inspiration for this one.
