I do not know how you are doing this, but if you are scattering single grass blades (one grass blade is selected as the scattered object), then it will definitely work much better if you create a simple object consisting of multiple grass blades, and then scatter those. So the rule is not 1 blade x 1000, but 100 blades x 10.

Not sure what your scene is like... but you can also apply this trick [fifth post down ( https://forum.corona-renderer.com/index.php/topic,9728.0.html )] to only scatter on surfaces your camera sees.
