Its kinda running on 2 engines i think, unreal for sure but also its running something else that can read the old scripts and physics stuff as they didnt rewrite that much to make it work in unreal. Thats why it feels like the old games. I think unreal is just for the gfx lighting to work and few other bits. Its weird aint it.
I just cant believe that rockstar/take2 has so much money from gta games i.e billions. That they didnt put the cash were their mouth was so to speak and offer one of the best remasters anyone would have ever seen but nope they did well with some things but a lot of it was ai upscaling then human tweaking some things tho not all things were caught, and obvious engine problems etc.
I really thought better of rs to do right by those games that helped put them on the map.
Dan housen or whatever he is called got out at the right time i think. Hope his new company does well. Maybe he can make some games that rival rs, since he was the main man for the gta games, well the story and writing and maybe other things iirc.
Btw i was wondering something. Is gta trilogy now running dx12 or vulkan or something older?
