I have older Mac (mini intel core duo 2). The game run very well in low, middle or high resolution. But I have a big unplayable graphic bug. All numbers card and 90% text in game dont rendering…
I now this bug is on PC too… maybe older with old graphic card.
Hope will be resolve quick, like I say game really run good with old computer; and I now Blizzard doing game for the most of gamers and "low" config too.
