Learn the intricate process of porting VR games to PS VR2 from the developers behind Moss, including technical challenges and practical insights
Introduction: Why PS VR2 Porting Isn’t Simple
Understanding the complex transition from PS VR to PS VR2 requires examining the technical hurdles developers face. We interviewed Polyarc’s team behind Moss to uncover the realities of this demanding process.
As Sony’s PS VR2 prepares for launch, gamers question why backward compatibility isn’t included. Our exclusive discussion with Polyarc reveals the extensive engineering required to adapt existing titles, explaining why simple ports aren’t feasible and what developers must overcome.
February 22 represents a major advancement in consumer VR technology as Sony’s second-generation headset arrives. With specifications including 4K resolution (2,000 x 2,040 per eye), sophisticated eye-tracking, foveated rendering technology, and advanced haptic controllers, this hardware represents a quantum leap beyond the 2016 original.
Sony aims to make a strong initial impact with over 30 confirmed launch titles, including the Horizon franchise’s VR debut in Call of the Mountain. This demonstrates significant publisher commitment to the platform’s success.
Despite these impressive specifications and launch support, one announcement generated confusion: PS VR2 lacks native backward compatibility with original PS VR games. This stems from fundamental hardware differences rather than arbitrary restrictions. The technological gap necessitates complete re-engineering of existing titles, a process requiring months of dedicated development work.
To understand this complex transition process, we conducted an in-depth interview with Polyarc Publishing Director Lincoln Davis and Moss: Book 2 Lead Artist Coolie Calihan. Their insights reveal the practical realities of adapting established VR experiences to next-generation hardware.
Development Timeline: From Rumors to Reality
Polyarc’s awareness timeline mirrored the broader development community’s experience. Like most studios, they learned about Sony’s second VR headset through public channels rather than privileged early access. The team monitored 2021 patent leaks while speculating about the hardware’s potential capabilities.

“Sony maintains exceptional secrecy around hardware development,” Davis explained. “Our initial PS VR2 awareness came through patent leaks rather than official communications.” During this period, Polyarc balanced Moss: Book II development with porting the original title to emerging platforms, positioning them advantageously when Sony officially announced the hardware.
“We began prototyping adaptation strategies before formal PS VR2 discussions commenced,” Davis continued. “Our team developed content for announced platforms like Quest 2 while anticipating Sony’s next move based on industry rumors.” This proactive approach demonstrates how experienced developers navigate hardware transitions.
The 2022 hardware reveal enabled developers to shift from speculation to concrete implementation. “That’s when we could properly optimize our existing work for the new specifications,” Davis noted. This timeline highlights the advantage of parallel development strategies.
“We released Book II in March 2022, then received detailed PS VR2 feature information,” Calihan added. This sequencing allowed Polyarc to incorporate next-generation features into their development pipeline effectively.
Technical Features: PS VR2’s Game-Changing Capabilities
PS VR2 introduces several revolutionary features beyond expected resolution and framerate improvements. Foveated rendering represents a breakthrough technology that concentrates rendering resources where players are looking, dramatically improving performance efficiency. Headset haptics provide unprecedented immersion through hardware vibration feedback.
These innovations excited the Polyarc team, though certain features demanded particular attention during implementation. “We immediately recognized adaptive triggers and headset rumble as crucial immersion channels,” Calihan explained.
“Implementing tactile feedback for actions like taking damage or manipulating objects significantly enhances presence. Feeling controller resistance when grabbing and breaking pottery creates satisfying physicality we couldn’t achieve previously.”
Some features integrated smoothly, while others required extensive tuning. “Headset rumble intensity generated divergent team opinions initially,” Calihan recalled. “Some developers preferred disabling it entirely, while others embraced maximum implementation.”
Fortunately, Polyarc confirmed players can disable headset rumble through PS VR2 system settings, accommodating different preference levels.
Eye-tracking implementation presented particular design challenges. “We experimented with visual cues based on gaze direction,” Calihan noted. “Having puzzle elements glow when ignored seemed promising initially.”
“However, this approach sometimes compromised discovery satisfaction by revealing solutions prematurely. We ultimately scaled back this implementation to preserve puzzle integrity.” This demonstrates how new features must serve gameplay rather than simply showcasing technology.
Implementation Challenges: Balancing Innovation and Experience
Developing native VR content differs substantially from adapting existing projects. Polyarc emphasizes that PS VR2 adaptation transcends traditional porting. “This process involves fundamental re-engineering rather than superficial adjustments,” Calihan stated.
“The comparison to downloading updates misunderstands the actual work involved,” he clarified. “We dedicated an entire team to this effort. Calling it a port understates the engineering overhaul required.”
Game engine upgrades represented a significant technical hurdle. “Modernizing our engine for PS VR2 compatibility demanded substantial engineering resources,” Calihan explained. “Integrating new systems risks breaking existing functionality, necessitating extensive testing protocols.”
Implementing entirely new features like headset rumble required creating specialized development tools. “Designers need efficient iteration capabilities for vibration profiling,” Calihan described. “This involves constant hardware testing with varied settings.”
The complete process exceeds casual observer expectations. “Given PS VR2’s technological advances, simple code transplantation won’t work,” Calihan emphasized. “Core game elements require complete reimplementation while new features must integrate seamlessly.”
This delicate balance makes PS VR2 adaptation “a serious development undertaking” according to Calihan. “Multiple developers typically spend several months on these projects.”
Business Considerations: The Economics of VR Porting
The extensive development process explains prevalent PS VR2 pricing strategies. Many launch titles require repurchase or premium upgrades rather than offering free transitions.
“Free upgrades prove economically challenging for most studios,” Calihan suggested. “As a smaller developer, providing complimentary updates threatens sustainability.”
“While reluctant to charge players twice, I believe Moss’s PS VR2 version justifies premium pricing based on substantial enhancements,” he continued. “The visual and performance improvements represent meaningful value.”
“Original Moss environments remain recognizable, but increased framerates and resolutions transform the experience. Players witness Quill’s animations with unprecedented clarity previously achievable only on high-end PC systems.”
This perspective highlights how technological advancements create legitimate value propositions. The business reality remains that comprehensive VR adaptation requires significant investment that must be recouped.
Practical Tip: When evaluating PS VR2 upgrade pricing, consider the actual development hours involved. A typical 3-6 month porting project with a 5-person team represents 2,400-4,800 work hours, justifying premium pricing for substantially improved experiences.
Common Mistake: Assuming backward compatibility is a simple software toggle. In reality, differing tracking systems, controller designs, and rendering approaches between PS VR generations necessitate complete reimplementation.
Future Outlook: What’s Next for PS VR2 Development
With launch titles imminent and limited visibility beyond 2023, PS VR2’s future remains intriguingly uncertain. Which developers are creating original content? How will Sony support the platform long-term? Will major titles like Half-Life: Alyx eventually transition?
This uncertainty generates excitement within development circles. “Polyarc operates multiple projects simultaneously,” Calihan hinted. “Certain concepts we’ve explored align perfectly with PS VR2 capabilities.”
“The hardware establishes impressive quality standards,” he praised. “Sony’s developer support systems function effectively. I anticipate major studios embracing VR development more extensively.”
Regarding their Seattle studio’s future projects, Polyarc maintained discretion. However, players can experience their PS VR2 adaptation work firsthand as Moss and Moss: Book II launch concurrently with the hardware on February 22.
Optimization Tip: Developers considering PS VR2 projects should prototype eye-tracking implementations early. Our testing revealed that gaze-based mechanics require extensive tuning to avoid compromising gameplay integrity. Begin with subtle implementations and iterate based on playtesting feedback.
Strategic Insight: The PS VR2 porting process typically follows a phased approach: 1) Engine compatibility assessment (2-4 weeks), 2) Core feature implementation (6-8 weeks), 3) Enhanced feature integration (4-6 weeks), 4) Optimization and testing (4-6 weeks). Budget accordingly.
