Without profiling, such statements carry little weight. In particular, for optimal performance unless you use data oriented design and structure using SoA vs AoS. However for a 2d top-down game where you have extremely good culling and layering, it’s possible you might be IO and GPU bound than anything else. Still, without profiling it’s hard to say.
