I'm definitely unable to make an AAA RTS laugh But I try to achieve an acceptable unit quantity beside enjoyable graphics quality, by simple methods, like very low poly models with close lod distances, restricted camera, and balanced function calls per frame.
Unfortunately only 3dgs Pro offers instancing, but only for sprites and particles. And I'm not planning to buy it, just upgrade to Commercial. Terrain LOD would help a lot, but I was not satisfied with it when tested with the Trial version...
