A primary concern revolves around the potential abandonment of id Tech in favor of Unreal Engine. Id Tech is renowned for its efficiency and performance, particularly in fast-paced action games, often outperforming competitors that rely on advanced upscaling techniques to achieve smooth frame rates. Microsoft has attempted to reassure the public, stating that numerous individuals continue to work on id Tech across various locations, directly refuting claims that only a minimal team remains. However, a former id Software employee, speaking anonymously, paints a more somber picture, asserting that the departure of critical personnel responsible for the engine's maintenance and evolution could lead to its eventual obsolescence. This individual believes that the institutional knowledge lost is immense and foresees a future where id Software will no longer be able to develop games using their bespoke technology.
