r100 and r200 drivers does not have it implemented, so there is nothing to disable .Last edited by dungeon; 08 April 2014, 02:01 AM.

. So it is known for ~15 years , but seems not 100% known to the opensource radeon developers to make stable implementation, so that it can deserve to be enabled by default .
For Unigine Heaven, yes some engines may use similar tehnics so hyperz does nothing there to improve performance .

I added the statement on its own, it may be a co-incidence though
R600_DEBUG=hyperz
^
that one. And now i have slower performance. It would seem my FPS is capped at 50. Yet I have a 60hz monitor? GLX gears is 50 and CounterStrike fps is locked at 50fps.. this is presenting a slowed down / juddering motion as its not vsync'd properly.
could that command have caused this? if so how to i turn it off?
also how do i change my refresh? Im using cinnamon 2.0 and there isn't a refresh control option, so i changed to 1280 x 780 and that is running glxgears at 60fps .. so im thinking some of the weird performance here is that 1920 x 1080 is somehow now running at 50hz ..
such pains running FOSS and AMD, not being able to easily select refresh ratesLast edited by ForkedPython; 08 April 2014, 05:11 PM.
