‘Viewfinder’ Probably Won’t Get VR Support, But a Standalone Game Isn’t Out of the Question
Viewfinder, a perspective-shifting first-person puzzle game, has been released on PlayStation 5 and Steam. However, despite the game's potential for virtual reality (VR) support, the developers have stated that a VR version would likely be a separate game rather than a direct port. This would allow for better integration of VR-specific mechanics and optimization for stereoscopic rendering. The developers also do not recommend using VR modding software with the current version of the game. While VR support is not currently available, there is hope for a future VR title based on Viewfinder. For more details, visit the source at Road to VR.
