@tijmens , is there a chance you are using a very large ground plane, or that the project in and of itself is rather big? If so, can you try reducing either or both just for troubleshooting purposes to see if that helps?
Please also ensure that your graphics card drivers are up to date, by acquiring the latest ones via the NVIDIA or AMD homepage directly, and not installing/checking them through Windows.
Should that not do the trick, please let me know and also send us a Feedback Report with your log files so that we can hopefully further identify the cause behind this. If not through the report, we may have to receive and have a look at the project ourselves if you’re able to share it. (I’ll then provide you with a safe and confidential way to upload the file)
Hi Demian, Thank you for your reply!
I moved the whole model to a new rhino file and placed it on the origin there. The old design was placed on the origin but somehow still had huge coordinates in the model itself. Now it works like a charm!
Happy to hear that @tijmens , and glad you were able to resolve it.
