Lets open things up a bit.
It’s way too high res, but the bottom corner reminds me of. . .
Seaman?
Yeah, but don’t bottom corners always remind you of that?
How cheeky!
Is that TLoZ: The Wind Waker by any chance?
Subnautica?
It was not Subnautica when @AquaMafia guessed it either ;)
No, none of you have it yet.
However there is a non trivial chance I may pick this some day.
Abzu?
Sea of thieves!
My guess is that its either 'really low resolution texture for a flag (in the rain*) simulator™" or maybe Risen.
*DLC
World in Conflict?
For some reason the three trails there remind me of a scene in NieR: Automata.
Tonight, hopefully.
