One of the most important parts of developing a high-quality ROBLOX experience for the iPad is ensuring smooth, stable, steady game-play performance. iPads are not as powerful as almost any modern-day desktop computer or laptop, which means our developers have to dig deep into ROBLOX’s code, uncover problem areas and tune them to run more efficiently, while keeping game-play quality in mind. The end goal is to have quality and performance exist in harmony; the challenge is pushing performance optimization to its limit without noticeably degrading the experience.

For the past month, the Client Team has been neck-deep in ROBLOX’s source code, identifying inefficiencies and re-engineering them in exchange for quantifiable and positive impacts on performance. One of the best benchmarks for illustrating their collective progress is Crossroads, a classic level the team has been using as an iPad testing ground since September. When we first launched the ROBLOX code stack on an iPad, Crossroads with eight players ran at an unplayable five frames per second (FPS). Today, it runs at a cool 30+ FPS.
