Unable to get higher than 1080p My full launch options:

PULSE_LATENCY_MSEC=60 WINEDLLOVERRIDES="dxgi=n,b" %command% -width 2560 -height 1440 -vulkan

. Using proton_5.0-rdr2-4

After the rockstar game launcher runs and disappears I had to type the following into terminal to get the game to launch:

PID=$(pgrep RDR2.exe | tail -n1); kill -s SIGSTOP $PID && kill -s SIGCONT $PID

I am using nvidia gtx1060, then the following message appears:

Please update your driver. Game requires version 20.2.2 or newer. Please visit AMD: http://support.amd.com/en-us/download for the latest display driver.

Pressed ok then the game starts to load.
