I've recently updated to the latest version of After Effects because in the previous version the "V" hotkey didn't work... Now the viewport doesn't work. If I load up a small template new project, the viewport will work maybe 60% of the time, but if I load a project, it works maybe 10% of the time.
I've checked my graphics card driver- it is up to date. I have an NVIDIA Quadro P4000.
Is anyone else having this issue? Any recommendations?
