I have a 15 sec video that gets stuck in the solving camera stage, takes forever. the app doesn't freeze, only delays. tested same video on other pc and it was done in less than 5 minutes.
My pc (drivers up to date):
i7 3.40 GHz
32 !RAM
nvidia GeForce GTX 1060 3GB
Win 10
After effects CC 2017.1 (14.1.0.57)
