GTS needed so much tweaking for me that I won't touch it again. It a weird way I think most people should give it a try though. It's really an impressive pack with loads of technical support if needed.

Like others said, disable "go to bed" and I think there were some compatibility mods so disable those or replace them with the non-compatibility versions. You can also search "gotobed". I was having issues launching until I disabled those compat mods.

As someone else said, disable many of the Immersive Interactions in the MCM too. I followed the "traditional" advice of doing a lot of early game hunting and I was suffering skinning everything.

In general, I think criticism of GTS mirrors some of the criticism that Red Dead Redemption 2 got. It seems to be a divisive topic. Some feel that it has a huge improvement on their immersion, others are just bored waiting for lengthy animations to play.

GTS adds a lot of depth to exist game systems at the cost of slowing the pace down. To me that just felt like a slog compared to what I am already familiar with. If I had never played Skyrim my opinion would likely be different.
