Tasked with improving performance of large architectural asset having over a million polys.
Lighting approach is hybrid with ray traced shadows and precomputed lighting and also using approx 100 stationary spotlights.
I was wondering if I should continue to focus on improving performance further by reducing the polycount of the mesh, or perhaps using instancing?
Or should I instead be focusing on reducing the number of lights being used etc?
stat unit shows that GPU is still the main bottleneck.
