Same problem here. It is definitely not a memory shortage issue, the system has 64 gigs of ram with less than 7 gigs in use and this problem occurs on new projects.
Have you found a solution?
I notice we both have GTX 1080 cards - it could be a problem with a graphics driver.
- Intel i7
- NVIDIA GTX 1080
- 64 GB DDR3 RAM
- Windows 10 Pro, x64
- Cubase 8.5.30 both x64 and x86
