In this video I try to showcase a comparison between C++ performance, regular Blueprints, and Nativized BPs.

The test spawns a large number of actors (10,000-30,000) with each actor executing small math calculations in its tick event. There is no visual component to the actors (as this alone would kill performance) but engine stats are displayed for each test to show more details.

The amount of actors goes up from 10,000 in the first round to 20,000 in the second and 30,000 in the final (regular BP has been excluded at the last test). The first test is heavily GPU bound for the most part as the scene features a lot of volumetric lights to create a less sterile scenario.

As a bonus, the very last two tests feature C++ and Nativized BP with  bRunOnAnyThread enabled (i.e.…
