Nvidia drivers and R20 viewport issues

Recommended Posts

Anybody else having viewport issues with Nvidia driver (390 series) and R20?


Basically my viewport lags like crazy on R20 with the 390 series drivers. I had to downgrade to 380 series to get rid of the issue. This sucks because I can't use the latest Redshift version 2.6.


I contacted MAXON tech support but they are kinda opaque saying they are working with Nvidia to resolve the issue. It seems MAXON doesn't have a public issue tracker so I have no idea how many people are facing this issue or if there are any updates. How does MAXON tracks bugs? Is it all over email?


This is the first time I have had a issue with C4D stability and I was always impressed by how stable the software is and now that I am forced to downgrade to R19 I am having a bad taste in my mouth...
