on bug 104744
from Roland Scheidegger
There is probably a reason why the game requirements state rx480 as a minimum... Even on macs its says amd cards newer than 2014, which excludes everything pre-gcn. I wouldn't be surprised at all if it actually fails due to the number of supported texture units, there are definitely games out there which require more than what pre-gcn hw can do. (With d3d10 apps can use 16 samplers and 128 resources, but with GL since resources and samplers aren't separated they are restricted to whatever the hw can do for samplers for resources too, which is 32 for newer hw (actually there's no hw limit but that's the limit just about every gl driver from any vendor will support), but pre-gcn chips can only do 18.) This would be mostly unfixable (well technically it would be fixable using some real ugly and complex hacks trying to deduplicate samplers but I doubt anyone will ever implement it). Albeit this is just a wild guess, it's possible there's legitimate driver bugs which cause it to misrender.
