Hello, I am currently working on a laptop with pretty good CPU, but equipped with only integrated GPU, what makes the renderings pretty slow and difficult to follow. I tried out all the different 'visual/quality' XML settings from http://www.mujoco.org/book/XMLreference.html#quality, but I am not able to get higher FPS than 20. Would you have any recommendation for setting the visualization setting to allow the renderings to run smoothly on slow GPU?
