There's also the branches of our multiverse where we simply don't experience heat death due to being on the unlikely side of the 2nd law of thermodynamics. Infinite simulations in those branches could account for a lot of "normal" experience. I haven't done the math but it seems intuitively like a simulation that keeps running in 10^-M branches (effectively quantum immortality) due to avoidance of entropy increase are more frequent than the 10^-N occurrence of boltzman brains where N>>M.
