LFC algorithms were more primitive in older monitors / older drivers, yes...christizzz wrote: ↑07 Oct 2020, 02:37thanks so this is normal that the older GSYNC acer doesnt have LFC ?
Hmmm. Then, I'm not sure why that is happening. One possibility is that the LFC is internally tuned to 60Hz instead of 48Hz in the drivers for some reason.christizzz wrote: ↑07 Oct 2020, 02:37I tsill dont undestand why also some flickers occurs in the pendulumn test when forcing the FPS tp 60...
Frame rate is constant , frame time is also constant.
To force consistent LFC behavior at 60Hz, you could try using ToastyX CRU to edit the FreeSync range higher/lower, to attempt to get the LFC window away from the 60.00fps area.
