Help, my planet is glitchy

I am trying to make a planet that is supposed to be of the arid hot with a dense atmosphere kind, like Venus.

My planet has 27,3 Earth masses and 3 times the Earth's radius.

Its current average temperature is at 493 Celsius (469-527). Its surface pressure is currently 16.8 atm (but it should have been a lot more).

Composition:
2.11 Earth masses of iron
25.1 Earth masses of silicate
6.67 Earth atm masses of sulfur dioxide
821 Earth atm masses of carbon dioxide

The problem:
1) Most of the sulfur dioxide and carbon dioxide is turned into a liquid. Part of the carbon dioxide in fact is rendered as ice for some reason.
2) When I click "vaporize all", atmosphere mass catapults to 827 Earth atmospheres, yet it is not rendered so. A few seconds later, the planet bubbles up and these two materials once again liquify into a global ocean.

Sometimes, I try replacing it with another planet with a rendered atmosphere haze, but when I scale the planet up to the size of the one I want, the atmosphere disappears and I have the same error again.

So what do I do?

FYI: My computer has 2178 MB of video memory and I am always warned that I need 4096 MB for the game to play properly. If that's the issue I guess I just can't solve it now.

Try disabling geostrophic wind in the planet's surface tab, it often causes glitches like this with high-mass planets

It wasn't totally solved. The liquid is gone but now it refuses to render the atmosphere even when I delete the gases and ad them again.

Go into visuals and manually set atmosphere opacity

How many stars are in your simulation? We're aware of an issue where, if there are more than 8 stars within a certain distance in a simulation atmospheres and clouds may not be rendered correctly.

However, it's also possible that the issue is related to the lack of video memory. It's a little difficult to know exactly what's happening without looking at the simulation itself. Are you able to share your saved simulation with us on the Steam Workshop so we can take a look at it?

It's a binary. Admittedly though a pretty unstable one and I assume this has to do with the lack of hierarchy between the barycenters. Or the overall complexity and low performance of my computer.

Thanks for sharing the simulation. Is the planet in question Atropos? That's the only one I saw that matched the description of what you shared above.

If so, I see that, for some reason, the simulated opacity of the planet's atmosphere is showing up as NaN, and I'm not entirely sure why. We'll try to take a look at this and see if we can figure out what's happening.

Update may break sim or object.

Correct. It's Atropos.
