Could AI game upscalers benefit from lightweight game-specific adapters?

A Reddit user proposes that AI upscaling technologies like DLSS and FSR could utilize lightweight, game-specific adapter layers to improve performance on low-power hardware.

• The idea suggests adding small specialization layers that capture a game's rendering characteristics while relying on an existing base model.
• This approach aims to achieve better image quality from significantly lower base resolutions, such as reconstructing 800p or 1080p from 360p.
• The primary benefit is saving GPU cycles, which is critical for handheld devices like the Legion Go where internal rendering resolutions may need to drop further.

The author seeks to determine if this direction has been explored in research or if there are fundamental limitations preventing its application to neural rendering.
