I would like to try playing in real Earth time i.e one game hour equals one real hour. I know there is a mod that does this although I can't remember the mod. Is it not also possible to do this by a console command of some sort? If so I hope there is a console command to undo it as well. Can anyone help? Thanks.

Yes you can do this with a console command. Open the console with ~ and type:

set timescale to 1

The default timescale is 30, and you can set it back any time.

One warning, according to the part where timescale is mentioned http://www.uesp.net/wiki/Oblivion:Console, it says that some issues can occur with certain quests if the timescale is changed.

Aye, "set timescale" be the answer.

The default setting of "30" bothered me almost from the start. I just couldn't buy in to time passing that quickly. It seemed unnatural. At some point during my first play-through I set it to "10". This is, for me, far more believable than the default. I've stuck with it ever since, though just recently (within the past two months or so) even "10" has occasionally seemed too rapid. "10" is not bad at all for my play style. My avatar does a LOT of road patrolling as a legionnaire for the Elder Council. We find that setting out from the Imperial City (where each assignment begins) at a reasonably early hour sees him enter Anvil during that same evening, allowing a decent night's sleep. Bear in mind that my avatar travels at a walking pace, even mounted, sprinting/galloping only for infrequent brief periods. Constant running/galloping would of course find my avatar at his destination far sooner, but such speed is unrealistic for a heavily armored warrior astride an armored mount. Besides, the slower travel pace helps conceal how small Oblivion's Cyrodiil truly is.

I sometimes think about looking for a mod that alters time scale for certain actions, reducing it to "1" for things like combat but otherwise leaving it at whatever the player has selected as default. I've also, like OP, thought of changing the default to "1". I decided against it because would tend to make me rely on "rest" too often for my liking. That, for me, is at least as immersion breaking as a too fast timescale.

-Decrepit-

Playing at 1 all the time would be far too slow. The answer would be TNO's http://www.tesnexus.com/downloads/file.php?id=27352 mod, where you can have the time scale you'd like for certain actions set automatically. Actions include when in combat, when sneaking, when in interior etc.

You could also use the http://www.tesnexus.com/downloads/file.php?id=36943 mod by Maskar.

I play with timescale = 5

I prefer slow timescales to fast ones; I find it more immersive.

Thanks for the helpful comments. On reflection, it may be best to set timescale to 10 or 5 rather than 1.

There is also this one.

Wow, what a wonderful mod idea! Every time I start to think I know all the wonderful mods out there and there can`t be anything new to discover anymore, I find a gem like this and ... I`m simply amazed. Amazed by the endless creativity of the modding community. Thank you for this link.

Is there a line in the ini file that controls the time scale?

OMG!! Thank you soo much for posting this. I've been waiting on a mod like this for the longest time! Think I started 2 topics on this previously asking for exactly this mod. Thanks again!

This topic is making me wonder how timescale = 3600 (i.e. one hour per second) would work. Probably not very well

Time scale factors over 1000 have a very high chance of crashing the game. When I was doing weather testing in Anvil, I set it to 1000. Day/night passed in mere seconds, but when I tried that in Chorrol, guaranteed to crash if I left it for more than about 10 RL seconds. Bruma hated it too. I think mainly because the AI can't keep up.

I like 10 also.

At 30, if you stop to pick a few flowers, the sun travels halfway across the sky and it's bedtime!

At 1, you can leave the IC after a late breakfast and slowly ride all the way to Anvil before lunch!

With 10, I find it takes a full sunup to sundown day of leisurely riding at a walk to go from one city to the next closest one, and that is about the scale I want for my character's Cyrodiil.

I concur. 10-12 seem to be the best timescales to match the size of Cyrodiil. Usually it means I can trek from the Imperial city to another town or clear a dungeon within an afternoon, which makes sense to me. Setting it to a 1:1 ratio feels weird. Against expectation, the world is too small / crowded for it to feel right.
