Three things I want to share:
1)I didn't have a single CTD after saving only with the console.
2)Stutter is gone. It may have something to do with
A Quality World Map mod because I used a classic map option which is said to cause problems with generating distant objects. Since I've been using another map, distant objects are more visible again and stutter is gone. Though I haven't been to the Rift yet so I don't know whether that area is "cured" as well because it was the most problematic.
3)I also fixed the yellow flashing that was caused by turning Antialiasing on. I found the solution on Google and it said to change settings in AMD Catalyst Control Center by checking the box "Use Application Settings" regarding AA. Checking these boxes worked and my screen no longer flashes yellow when in 1st person. Hope it stays that way.
