Fusion 360 was complaining about my outdated graphics driver, so I updated it (via Nvidia Geforce Experience). Since then, the live view of Keyshot doesn't update anymore.
Operating System: Windows 10 (64bit)
Graphics card: Nvidia GeForce GT 740M
Graphics driver: 425.31
Processor: Intel Core i7-3632QM (2.20GHz)
I am trying to resolve this issue by re-installing the graphics driver. Will update this post if that has resolved this issue.
