matlab slow start after installing R2017b and configuring opengl

Hello. Several months ago, after upgrading from R2014a to to R2017b, I discovered that my complex graphics had poor resolution. I was informed about the changes in the graphics language and ran the opengl utility to configure the graphics options for hardware support. After doing that, I noticed that matlab started slowly, sometimes taking 2 minutes or more. I could not find a solution to the slow starts anywhere. Then, recently, after a matlab crash, matlab started very quickly, but I saw a warning that the graphics language had been updated in R2014b, and that I should configure opengl. Now, having specified opengl options for full hardware support, I find that it again starts slowly, as before. Am I doing something wrong with the configuration of my graphics language options? Below, I enclose the opengl.data results:
Version: '3.1.0 - Build 9.17.10.4229'

Thank you for your advice and assistance.

Thanks for posting the question here. I have encountered the same issue as you. After searching a while, I found the reason. It looks Matlab has selected the integrated GPU card for rendering OpenGL, not the dedicated GPU card. This can be changed through Nvidia Control panel, which allows the user to select GPU for specific programs. Hope this helps someone have the same issue.
