Once again, I think I have fixed judder

This will be the third time I believe my judder is fixed. It has always happened after 20-30 minutes of play. The first time I thought I fixed it was when I more firmly secured the Lighthouses. But then after playing a couple times it was back, if it ever really left. Second time I put an extra fan in my MiniXT case and it came back. This time I have played 3-4 times and it seems gone. Unfortunately, I did several things at once so I don't know for sure which one actually fixed it. I installed Process Lasso set it to Gaming Mode, added a USB 3.1 card, and then I noticed Display Mirror wasn't checked so I checked it. Of the three things, it could have been any or all but so far it is working with only minor judder when loading and none noticed during game play. If it stays fixed I'll update.
