I just checked and it says 13.91, opened the model and now it works fine (everything now it's pretty fluid). Did the program updated in the background and that's why it got fixed or this is something that happends from time to time?
It definitely doesn't update in the background. If you were getting a lot of lag before, it could just be that whatever other programs you had running were using up your RAM/GPU and not leaving enough space for RahiTuber to run. Running a game without a framerate limit would do that, for example.
