from Roland Scheidegger
There is probably a reason why the game requirements state rx4=
80 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 a=
re
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 abo=
ut
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 anyo=
ne
will ever implement it).
Albeit this is just a wild guess, it's possible there's legitimate driver b=
ugs
which cause it to misrender.
