Wizardry 8 is hard by design and people that make easy mods are missing the point imo but you can find anything you want to know
https://www.zimlab.com/wizardry/recovered/flamestryke/wizardry8/flamestrykes_w8.html or of course the wiz 8 forum here on gog
https://www.gog.com/forum/wizardry_series#1673760687 if you install Wiz8 to Windows 10 then you will NOT get the sample files but others have posted them in the forum if you want those
p.s, yes of course BG3 runs best on Windows 10 because that is the system its designed to run on... it can run on 11 or 8.1 but 8.1 is now finished
if you are looking to upgrade a system from 8.1 to 10 then its free but your Gpu is prob too old to play BG3 as its EA and needs a 1/2 decent card
the forum for bg3 on Gog is
