Astral Chain PC Port Adds DLSS 5 and Uncapped Framerate, Removing Switch’s 30 FPS Lock

PlatinumGames' Astral Chain now has a native PC port. A port which removed the 30 FPS cap seen in the Switch version. It's an important update as the frame-rate limit has deterred a lot of people from playing the game again on PC. The update puts it in remaster territory thanks to big visual and technical improvements.

AI-assisted reverse engineering brings richer visuals and technical improvements

DLSS 5 neural rendering technology is supported with the port. The way it's implemented adds more details in textures and a bit more moody lighting to the environments. Most of the code, tools, and reverse-engineering work was done with Claude Code from Anthropic.

Controllers beyond Xbox have been added as of the November 4 update. The port also includes experimental uncapped frame-rate, in-game settings menu, and rumble support. This makes it a lot easier to play and configure on PC depending on your hardware.

The effort demonstrates how AI can help reverse engineering and documentation. Most of the code was done by Claude via Claude Code, according to the developer. This technical feat makes the Switch exclusive look like a remaster on modern PC.

The native PC port removes the 30 FPS cap seen on the Nintendo Switch version. It's an important change since the original framerate limit kept a lot of people from replaying the game on PC. The update puts the game in remaster territory with some big visual and technical improvements.

    1. It appears to be an unofficial native port. The developer used Claude Code for the reverse engineering work to achieve this.

  1. Linux users are likely out of luck here. Anti-cheat or proprietary API calls usually break Proton compatibility on these ports.

  2. The lighting improvements are nice but I worry about the stability of the uncapped framerate on older hardware.
