Introduction.Explicit and implicit type casting is a common programming topic for almost any imperative programming language.Most C,C++,or Pascal programmers care about efficiency and speed of their code; but those who use managed programming environments,such as Java,Visual Basic,or C# rely all the optimizing tasks on the compiler and the runtime environment.casting speed Dark Souls 2 WikiAt absolute best,this puts 348 casting speed at ~6 frames faster than 120 casting speed.This comes to about 0.2 seconds.Comparing 120 casting speed to 266 is approximately 4-5 frames faster,resulting in ~0.14 seconds faster casting.This confirms diminishing returns on casting speed.More testing is needed to get exact numbers.
