Black Myth: Wukong, Frostpunk 2, Palworld, Stalker 2, Tekken 8, Silent Hill 2, and Avowed are all developed using Unreal Engine 5 (UE5). These games have shown inconsistent performance on PC platforms, with social media often blaming UE5. Avowed, developed by Obsidian Entertainment, has erratic frame rates and unconventional upscaling techniques but is visually impressive and generally smooth. Silent Hill 2, developed by Blooper Team, faced bugs and inconsistencies at launch, although patches have been released. Both Obsidian and Blooper Team have experience with Unreal Engine, raising questions about performance issues. Critics compare UE5 unfavorably to Id Tech 7, a proprietary engine known for high performance, due to the extensive customization available to its developers. Unreal Engine is versatile for game development and other applications but presents challenges in transitioning from simple projects to AAA games. Epic Games is addressing common issues like shader compilation stutter and traversal stutter in UE5, but large developers face challenges in updating code without introducing new issues. The timing of game releases often leads to less-than-ideal launch states, with the expectation of post-launch fixes. Avowed may also require adjustments after release, depending on its commercial success and the resources available to Obsidian, who is also working on a sequel to The Outer Worlds using UE5. The main challenge for developers is time, which affects the quality of game releases.
