My laptop screen, brightness can be adjusted. Usually a moderate amount of daylight, or just my lights. My room isn't extremely bright, but making it brighter or darker doesn't really make the maps any more pleasant to look at. I only have this issue with mapgen snow maps, by the way, other snow maps are fine
this is with fog of war disabled, and its quite difficult to see the mexes, especially if i have my laptop brightness down. i tend to up my brightness a lot when playing snow maps, when i'd rather not
