Wanted to provide a quick update. I have looked over the log on the chromium.org ticket and based on the information in Comment 10 I did the following:
Updated drivers for Intel UHD Graphics 630 GPU to latest driver provided by Dell, the computer manufacturer. Version now installed is 188.8.131.5235.
Updated NVIDIA drivers for the NVIDIA 1070 to latest driver from NVIDIA. Version now installed is 461.40
Attempted to run Chrome from command line with the parameters provided and received message “Google Chrome cannot read and write to its data directory”
After these attempts the SF interface still unresponsive for 10+seconds before model starts to load. Rechecked Edge and Firefox and responsiveness and model loading is nearly instantaneous.
Computer is a Dell Alienware 17 R5 laptop.
As stated earlier, this machine has not had the problem until about a week before my original post date.
There is also a 12 second delay of unresponsiveness when attempting to change 3D Settings on a model. This delay includes none of the settings options on the left to load until after the delay.
Thank you again for all the help and your continued efforts to solve the issue.
