Inside Virtuos' Switch Ports: How BioShock, XCOM 2 and Borderlands Were Optimized for Nintendo Switch

2K Games leaned on third-party partners in 2020 to bring major collections to the Nintendo Switch, including BioShock: The Collection, XCOM 2 Collection and Borderlands Legendary Collection.

Those ports were handled by Virtuos, a studio with a strong reputation for platform conversions and co-development.

In an interview with Automaton Media, Virtuos engineers outlined the systematic approach they used to adapt these AAA titles to the Switch’s hardware constraints and gameplay expectations.

Virtuos described a methodical, hardware-first workflow.

They began by playing the builds directly on Nintendo Switch hardware to identify specific performance hotspots—places where frame rate or responsiveness degraded.

Once those hotspots were catalogued, the team profiled both CPU and GPU workloads to determine root causes and assembled a prioritized optimization plan that balanced engineering effort against quality impact.

According to Virtuos’ lead engineer, the team prioritizes CPU-side optimizations because changes to CPU load can often be achieved relatively quickly through resolution and graphics setting adjustments as well as code-level improvements.

They explained that CPU optimization requires a detailed understanding of feature implementation and a strategic redistribution of CPU resources—work that is time intensive but frequently yields substantial frame-rate benefits.

Virtuos also emphasized maximizing the Switch’s native GPU features before resorting to image-quality reductions.

The Nintendo Switch uses NVIDIA’s Tegra X1 SoC with a Maxwell-based GPU architecture, and port teams will often leverage the console’s inherent rendering capabilities to preserve visual fidelity.

When necessary, the studio rearranged graphical features by priority and simplified or removed lower-impact effects to stabilize performance.

The overriding principle, Virtuos said, was that maintaining a stable frame-rate and consistent player experience takes precedence over matching the visual feature set of more powerful platforms.

These insights underscore why porting triple-A collections to Nintendo Switch is a blend of technical profiling, platform-specific rendering decisions, and clear prioritization.

For publishers such as 2K Games and port teams like Virtuos, the goal is delivering playable, polished experiences on Nintendo Switch—whether distributed digitally via the Nintendo eShop or through retail—while respecting the console’s hardware limits.
