we have problems with a SketchUp Pro 2019 Windows version and a new RTX2080.
The checkup tool shows no video ram, but I found some hints here in the forums this might be a known bug from the checkup tool.
Anyways SketchUp is way slower than it was with the older GPU (AMD Radeon), but GPU drivers are up to date. Latest SketchUp Update is also installed and GPU benchmarking tools show the expected performance of the TX2080, just SketchUp wont work.
I tried some nvidia settings, but nothing changed.
OK, little update to this issue: We are still having trouble. We replaced the motherboard + CPU + RAM, new Window 10 Installation and the issue is still around: SketchUp seems slow, especially when opening/sending to layout, turning and zooming is awefully slow, shadows are loaded really slow etc.
Yes, we are trying to navigate with textures and shadows on. We are aware this needs more performance, but since our direct comparison with the former Radeon card looks better than the RTX2080, we think there should be another issue with SU and the specified GPU.
