Ehm, I don't want to repeat something already discussed in another exchange, but don't forget that most probably he is also using the machines to play, since both his machines are really "gamer" machines, and his main machine (by his indication) is the one with the 4090, so that one is also the ones he uses to play games.
Estimated earning (let's keep it to the low end), 10k per month in the last month (

), realistic, given the indication of 4100 paid subscribers.
Actually, I am being conservative, 10k with 4100 subscribers would mean each subscriber is giving a bit less than 2.5 USD per month, while most probably the amount per person per month is bigger, not difficult to see why he wants to keep it going for as long as he can, Lara is his cash cow (evil pun on some "size", intended
:-D).
Would not be suprised if it is also a reason why, despite bestiality, Patreon has not bothered him, a creator that makes at least 10k per month and has 4100+ paid subscribers and 9100+ total subscribers (potentially meaning additiona paid ones), interest the credit card companies and Patreon as well, for the transactions and commissions fees ;-).
About the sims, actually, being fluid sims in general can mean double precision, so, no need to dedicate or buy an rtx4090 for that.
In double precision, in theory a RTX4090 does around 1.3TFLOPS on that (with slight variations between models), and RTX2080 0.314-0.42TFLOPS (depending on exact model), a good old Titan V (ca 800-900 second hand from China) does 7.45 TFLOPS, between five and six times the speed of the 4090.
I did not measure exactly, but I have seen it even in practice, running some double precision simulations, two newer RTX A5000, despite being newer etc. cannot compare with the speed of a Titan V.
If like someone had indicated, he is from former or actual (it can be a sensitive subject, that is why I put it this way) Eastern Europe, that means his earnings from Patreon put him in "criminal-level" income, but doing something that is legal (well, excluding the possibility of fiscal evasion, and unless turns out his country has a law against NSFW animations).
Though, it is not my kink, but still, since he is "milking" Lara, maybe he could add up a scene on that ?
:-D :-D
