Hello!
Just a quick note about the map when spanning the desktop. I have an RTX 2070 card that runs 4 monitors. 3 along the first row and one up top. When I play RDR2 while spanning the desktop across all three monitors on the first row (very cool by the way!) the map does not span with the rest and as a result is confined to the middle monitor, but squished. So basically, it is confining what should be a 5760x1200 map into a space that is 1920x1200 so it is distorted.
If you could add this fix to your todo list, that would be great. Otherwise, it's running very nice.
