--- Comment #1 from Roland Scheidegger <sroland@vmware.com> ---
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.
