Venus might lose the runaway greenhouse effect,and who knows? But Mars would just likely be a warmer dead rock than it is now.

This doens't make the slightest sense.
It doesn't matter how many universes there are, physical vs virtual.
What matters is whether you're more likely to be born into one kind or the other, based on the relative populations of each.

Lets's not forget, no matter how strange any given universe might be, 2 plus 2 will always equal 4.
Similarly, the precepts of math in general, and CS in particular will still hold true.
Any computing device in a simulated universe has actual computing power, and that computing power must be a subset of the computing power of the parent simulator.
You can't just magically add more computing power just because "it's a new universe".
That means that whoever built the outermost simulator(s) had to decide how powerful to make them, and they decided how much of their univeres's complexity (potential computing power) to dedicate to simulation, and how much to leave themselves to live in.
If they chose to limit the computing hardware enough, they may have left more potential reality outside the box than inside.
That would mean more people live in the outermost physical universe than within the simulation.

And yes, they could run twice as many virtual people at half speed, but there's still only so many people-hours the outermost simulator can run per hour of real-time.

There's NO reason to believe virtual people outnumber physical people.
