24 fps lock on OpenGl and Vulkan

[Jelektronik]

Hi, on my machine i see 24 fps lock on OpenGl and Vulkan with 1920*1080. If i switch on lower resolution all good. Reinstall windows not helping me. Win10 + AMD R9 290.

And DirectX 11?

[Jelektronik]

Direct X11 - OK.

The problem is still there...

There were other reports related to wrong timing with some AMD drivers on 1920x1080 resolution.

Now i am using 17.1.2

Same for me (used 17.1.2 and today with the newest 17.3.2). It seems like to be a
"24 hz lock with Vulkan & FreeSync" as my monitor states it's running at only 24hz .
Disabling VSync while leaving FreeSync activated does not help.

For any reason, disabling FreeSync (in the Monitor Options) removes that bug for me - then I get "normal" 80-110 fps & 144Hz (again VSync doesn't matter).
Reenabling FreeSync while still being ingame changes nothing - so then I still have 80-110 fps & 144Hz (but I don't now, if FreeSync is really activated, or if the game did just override it)
However, if I restart the game (with FreeSync still enabled) the 24hz-lock is again there!!

Edit: With DirectX 11 & FreeSync, I get "normal" 80-110 fps & 144Hz. So this Bug only occures on Vulkan (or OpenGL) AND FreeSync


My System:
Windows 10 x64
Intel Core i5-6500 3,2 GHz
Radeon RX 480 8 GB GDDR5
16 GB RAM
Monitor ViewSonic XG2401 (144Hz with FullHD, FreeSync)

We are shipping a patch which requests refresh rate explicitly, as when we leave it up to the driver, it seems to select minimum possible, instead of maximum supported. It should be in the next patch, I think.

Thank you very much for the fast answer :)
