So I decided to update to the new AMD driver 15.7. But after it finished, I cant choose 144hz anymore. There is only 120hz. My card is R9 295x2 and my screen is a Asus Rog Swifr PG278Q. Someone have the same problem?
Nope, it's there for both of my screens.
Maybe it didn't install or uninstall correctly?
A setting enabled or disabled that shouldn't be?
The only 2 things that I can think of for the cause.
hm... weird. Havent changed anything. Already tried to uninstall my drivers via DDU. It works with the Omega Driver but not 15.7
144 works for me fine. check u monitor in devices manager.
I have exactly the same problem. 14.xx drivers all allow 144hz but 15.xx drivers limit me to 120hz.
They might have limited this particular monitor to 120hz because many reported issues at 144hz. Mine worked ok with most 14.xx drivers at 144hz.
Some user which had flickering at 144hz claims to have fixed it with this method
Fix for 144Hz flickering on ROG Swift PG278Q with R9 290X
Checking the ROG swift pg278q FAQ you will find following text
"Max Refresh Rate: 144 Hz* (AMD Radeon graphics cards are currently driver limited to 120Hz)"
hope this gets fixed or i'll have to go back to the 14.xx drivers
