still crash for me too, i wait month for fix
ASUS R9 390, win7, 15.8 beta (non strix)
Also try on 15.6beta, 15.7, 15.7.1 with hotfixes. All not work.
Sorry for bad english
Aaand this problem not in "Known issues" on driver page. Why?
Not only 390 have problem, also 280x and 290 crash on gtaV win10.
I am having the exact same issues with Sapphire 390 on Windows 10 64-bit machine. I have found that play times can vary from 2 minutes to about an hour before the AMD driver crashes and recovers itself, leaving GTA in a frozen state.
Attempted numerous 'fixes' as suggested on forums around the internet including:
-playing in safe mode
-Changing DirectX to 10.1 and 10
-Turning of FSAA and MSAA
-Lowering Mem clock speed of Graphics Card through MSI AfterBurner
-Clean install driver 15.15 instead of 15.20.
-Removing suggested applications including Firefox / Chrome / Rainmeter or programs that use Graphics accelerators.
While some of the above fixes has at times increased game stability, GTA still inevitably crashes sooner or later.
Putting GTA V on the shelf until this is resolved (fingers crossed)...
