LÖVE

I'm new to LÖVE, but out of all engines I've tried so far, i LOVE(couldn't resist, sorry) this one the most. I have an issue however, I'm starting development of a 2.5D game where Im doing whole projection math myself and therefore I have to draw all the polygons myself too.
Currently Im doing over a 1000 love.graphics.polygon calls (fill mode, convex) per DRAW cycle and so far it's all smooth. However I'll have to render more stuff eventually, and when I artificially inflate that number to 10k to test things out - FPS starts to fall.

So the question really - maybe there's a more optimal way to draw a lot of shapes than doing thousands of love.graphics.polygon calls per frame ?

Thank you all in advance !

Hey! Thanks so much for the response. To answer your question - that's because I never really programmed anything that would use hardware acceleration before, so I even didn't think of that. But that's probably what I'll go with, since I want maximum performance.

If you (or anyone reading this) have any links for beginners on using vertex shaders in LOVE - that'd be greatly appreciated! Thanks again!

vec4 position(mat4 transform_projection, vec4 vertex_position)
{
    // The order of operations matters when doing matrix multiplication.
    return transform_projection * vertex_position;
}
