Episode notes
How Arseny Joined Roblox
- Arseny flew in for an interview and joined Roblox in 2012 from console game studios.
- He wanted to work on engines and platforms, not just content.
Owning The Tech Stack Enables Fixes
- Roblox iterated multiple rendering engines and gradually increased ownership of the full stack.
- Owning more layers made fixing performance and quality problems easier.
Hybrid Client-Server Simulation Model
- Roblox runs simulation both server- and client-side rather than a thin video client.
- This hybrid model lets the platform trade compute, latency, and fidelity per device and context.
