Eurogamer technical expert Oliver McKenzie has released a teaser for The Callisto Protocol on PlayStation 4 and Xbox One. According to Digital Foundry, the developers made some serious compromises, but they still didn’t achieve the ideal.

There’s been a significant downturn in almost every aspect.

• Texture quality is greatly reduced, parallax occlusion and decals maps are not at all, some textures are very long to load, some are not loaded to the end.

• Object geometry is simplified to the limit, shadow maps are reduced in quality.

• Good quality lighting and character models.

• Shadows and post-processing effects are better on PS4 Pro and Xbox One X.

• Xbox One — 720-900p.

• PlayStation 4 — 864-1080p.

• Xbox One X/PS4 Pro — 1368-1440p.

• The opening sequence is pre-recorded, the clips are rendered in real time in 24 frames.

• The frame rate on the Xbox One is very unstable, often below 30 FPS, especially in combat; the PS4/Pro is better, but suffers from severe slowdowns.

• The One X has the most consistent frame rate.

• McKenzie noted that the Series S version of The Callisto Protocol is by a wide margin better than the One X version.

The Callisto Protocol was released on December 2.
