从家用游戏机到PC虚拟现实游戏:《不语者》给我们的启示

《不语者》(Unspoken* ) 是一款由 Insomniac Games* 公司开发的第一人称魔咒虚拟现实游戏,采用了 Oculus Touch* 控制器。 Insomniac Games 是一家经验丰富的家用游戏机开发公司,他们的内部引擎经过扩展后可以支持虚拟现实。 从帧速率为 30 fps 的家用游戏机,到高端虚拟现实设备上的 90 fps,帧速率的大幅提升要求更好的性能感知设计,以及引擎性能改善,以实现最大程度地利用系统资源。 本文介绍了如何检测系统级别的引擎中所存在的技术瓶颈,其背后的原因是什么?以及如何消除这些瓶颈以提升性能。
