Yeah, unfortunately to render at any decent speed requires some pretty crazy hardware. And the reason I am raffling the 4090 is I'll be replacing all cards with liquid cooled cards, and I'd rather buy it with the block then void the warranty considering how vital the cards are for me to continue this, kind of need those warranties.
and worse case scenario, the day I release to steam, I'll do a dump of all purchases made here before that day, and just email everyone the keys, not the preferred option, but its an option.
