CO2 bug?

[Lokisaga]

Hello,
I might be wrong, but I remember hearing about a bug with the CO2 levels if you alt-tab out of SHIII. As I recall, minimizing the window that SHIII is running in while submerged can cause the CO2 level to "stick" at it's current value even after you surface the boat. This bug can be fixed by repeatedly saving, exiting, and reloading the game.

I have noticed, in my days of stock SH3, my CO2 gauge would take about 5-10 minutes of running on the surface before the air throughout the boat would be refreshed. Makes sense, it takes time to ventilate the entire thing, not seconds after the hatch is opened. And if the waves are too high, and keep breaking over the conning tower, forcing the watch crew to hold their breaths, it can delay the whole procedure.
I'd be concerned if the air does not refresh within 1 hour of normal surface running with calm, flat seas. As I've said, I rarely have to wait longer than 15 minutes, with the worst weather.

Sticking CO2 values when alt+tabbing?

I do that probably thousands of times during one patrol and have had no problems. I do use the CO2 changing h.sie v16 and Stiebler 4c patches, though.

I stand corrected.

SH3 is such a quirky thing that I would not be surprised at all if the CO2 really got stuck with some players. I meant to say that, that does not happen to me, but it might still happen to other players.

Yes, your information is quite correct. The CO2 problem after ALT-Tabbing and the work-around have both been thoroughly discussed on the SubSim forums. But only in SH4, not SH3. AFAIK, that problem has has never been confirmed in SH3.

@kvbrock82: If you are experiencing such a problem, please first post your mod list, because it it not common in SH3, and second, try the work-around of saving, exiting the game, and restarting. It does work in SH4. It might work for you.

Alright. Well, it's good to know I'm just confused, and I'm not completely imagining things.

The oxygen in the air in the boat is a different story. Once you return to the surface and the hatches are opened, the oxygen is quickly replaced by exchange with the outside air. Takes a couple of minutes. Then you can dive again, but only until the oxygen level goes down to 17%. At that point, the crew has to get more oxygen, either from the tanks or from the atmosphere.

Though it should be noted that in real life renewing the boat internal atmosphere would typically take quite a bit more than the "couple of minutes" the game often displays. For realism sake I would suggest at least a quarter of an hour.
