BTW I've tried running multiple large mods that specifically list dsound.dll as a requirement, but if I'm not totally mistaken (I'm pretty new to modding GTAV, like 5 days into my journey) everything seems to run correctly WITHOUT dsound.dll but WITH xinput. Should I discover I'm mistaken (if you know for sure, let me know) then I guess I could still inverse the choice - throw out xinput and re-activate dsound.dll.
But for now, I guess "if it ain't broke don't fix it" HAHAHA
Will try my luck with a few smaller, "single" mods by V8Enthusiast next, they come in .dll format which seems a bit odd to a noob like me, but based on their recent updates these mods - like "Garages & Dealerships", to name one, should all work with both Legacy and Enhanced...
I guess things could still crash in countless spots on the map, so I will have to further sacrifice myself with some actual GTA V Enhanced GAMING too! I know, it's a hard knock life.... My learning of the day (listen up, other noobs!): Make "snap shot backups" when a nice setup has come together. Also: Backup of vanilla. And backup only with modtools, but no mods.
Not hard to screw up smth small - and I found troubleshooting the latest problem is much more painful than just going back 2 steps to a fine-working setup that ran fine (even if it's a >100 GB large snapshot). All hail SSDs! <3
