--- Comment #3 from François Gouget fgouget@codeweavers.com --- Created attachment 73905 --> https://bugs.winehq.org/attachment.cgi?id=73905 No refresh rate shown for QXL
I have looked into the configuration and this confirmed that neither w11pro64_amd nor w11pro64_nv support Variable Refresh Rate. Their refresh rate is set to 60 Hz.
Also note that when I said the values change "a bit" from one run to the next it's really just a bit. Whereas they should be 166667 for 60Hz the test gets 166653, 166671, 166674, 166686, 166703, etc. So I think the driver is somehow 'measuring' the refresh rate and getting minor timing variance.
Another interesting point is that with QXL the Windows 11 parameters dialog does not report a refresh rate. But when checking the display adapter properties one can see that "List All Modes" shows all refresh rates as 64Hz which matches the 156250/10000000 value reported by the test, but also matches the duration of a standard timer tick!
