Figured I’d throw this out there: does anyone know the fastest way to *conservatively* rasterize lines on GPU? I’ve tried: (1) drawing instanced thin quads; (2) drawing thin quads w/o instancing (~15% faster); (3) glLineWidth(2.0) (fastest on NVIDIA, but deprecated)

Yeah, the problem is the spec doesn’t require glLineWidth to be supported with anything greater than 1. ANGLE supports only 1. Metal and D3D don’t support line width at all, though D3D does support antialiased lines so that might be an alternative.
