Quoting myself from a day ago - "The problem is thinking that the product of a programmer is code. It isn't, really, the code is just the final stage. The actual valuable thing the programmer produces is the underlying mental model. Without that, the code is just tech debt"

Been a hot minute since I spoke at GCAP but I’m BACK This time talking about CPU performance on CONTROL Resonant; a mere week and a half after we launch! Stutter struggles were real so I’ll be discussing how we tried to solve some of the worst offenders Join me on Monday 5th Oct 14:00 - 14:50
A screenshot of my talk summary.

Getting Northlight Performance Under CONTROL

CONTROL Resonant is Remedy's densest game to date, with entity and component counts massively exceeding anything the engine has seen before. As a result, the Northlight Core team had to re-evaluate our approach to many of the runtime systems.

In this talk, I’ll provide a high-level overview of the different parts of Northlight and break down a series of CPU-side frames in CONTROL Resonant's "airlocks". Within these frames, I’ll detail both the attempts made and the actual solutions used to solve the ‘Stutter Struggle’ we repeatedly encountered, including discussions of world streaming, data transformation pipelines, ECS and resource management.

I have reserved this opinion for a long time but now the hater gates are open. Mario is set in 1981, a time where a New York plumber's access to guns was plentiful and based on a simple google search shows the surge of popularity around the Beretta 92 means Mario was surely carrying.
