LEGO Batman: Legacy of the Dark Knight PC specs raise concerns over Frame Generation use

TT Games has shared the PC specs for the upcoming Unreal Engine 5 game, and the minimum requirement lists 1080p at 30 FPS with FSR or XeSS Balanced and Frame Generation enabled. That is unusual because Frame Generation is normally meant to improve an already smooth frame rate, not make a low frame rate barely playable.

The concern is that the game may be using Frame Generation to raise performance from a much lower base frame rate to 30 FPS. That can create problems because generated frames do not reduce input latency in the same way as real rendered frames. If the base frame rate is too low, the result can feel less responsive and may show more visual artifacts.

NVIDIA, AMD, and Intel generally recommend using Frame Generation on top of a stable, higher base frame rate. It works best when the game is already running smoothly. Using it to reach only 30 FPS could lead to ghosting, lag, or uneven motion, especially on weaker PCs.

The minimum GPU list is also fairly modest, with support for cards such as the GTX 960 4GB, Radeon RX 6400 4GB, and Intel Arc A580 8GB. Still, needing upscaling and Frame Generation even at Low 1080p suggests the game may be demanding on older hardware.

Here are the official PC requirements:

The recommended and 4K targets also include Frame Generation, which means the feature appears to be part of the game’s expected performance profile across all tiers.

This is also the first LEGO game to move from TT Games’ older in house technology to Unreal Engine 5. That change could bring better visuals, but it may also make open world performance more demanding.

LEGO Batman: Legacy of the Dark Knight launches on May 22, 2026. The final performance picture will become clearer once players and reviewers test the game on real PC hardware, but the early specs suggest low end systems may need to make serious compromises.
