Unreal Engine 5 supports NVIDIA's DLSS technology, which uses AI to make games run more smoothly on compatible graphics cards by generating additional frames and sharpening images — without the full processing cost of rendering everything natively. Epic has also integrated NVIDIA's ACE tools, which give developers AI-powered options for animating digital human faces and generating NPC speech.
Details
NVIDIA provides Unreal Engine 5 plugins for DLSS 4, which encompasses several AI-powered graphics features: Multi Frame Generation (creating additional frames between rendered ones), Ray Reconstruction (improving lighting quality using machine learning), and Super Resolution (upscaling lower-resolution images to appear sharper). These run on-device using NVIDIA's RTX graphics processors. At Unreal Fest 2024, NVIDIA also released UE5 plugins for its Avatar Cloud Engine (ACE), which includes Audio2Face-3D (AI facial animation driven by audio input), automatic speech recognition, small language models for NPC dialogue, and text-to-speech generation. These are NVIDIA-developed technologies that Epic has integrated into its engine as optional plugins, not Epic-developed AI systems.

Other practices by Epic Games
OtherAfter widespread protests from artists in December 2022, Epic's portfolio platform ArtStation introduced a "NoAI" label that artists can apply to their work to signal they do not want it used in AI training datasets. Epic also updated its terms of service to commit that it will not use or license any ArtStation content — labeled or not — for AI training purposes.OtherEpic provides a plugin for Unreal Engine 5 that lets game developers train AI-controlled characters and agents by having them learn through trial and error — similar to how a person gets better at a task by practicing. The tool, called Learning Agents, launched as an experimental feature with Unreal Engine 5.3 in September 2023 and is aimed at developers, not players.OtherFortnite uses an algorithm to match players of similar skill levels against each other rather than grouping players randomly. To fill out lower-skill matches, the game also adds AI-controlled bot players that are designed to behave like real players. Both systems have been active since 2019 and remain among the game's most debated features.
