G-Rebels Receives New Steam Demo with Major Performance Improvements Ahead of Early Access

Developed by Reakktor Studios and published by Senatis, G-Rebels is an upcoming action flight simulation heading toward Early Access on PC via Steam. Shortly ahead of that release, a newly updated demo is now available, introducing significant performance optimizations alongside refined controls and expanded world detail.

The latest demo update focuses primarily on technical improvements driven by community feedback. Performance has been substantially optimized, allowing the game to run more smoothly across a wider range of systems, including lower-end hardware. At the same time, users with high-end PCs can enable a new “Insane” graphics mode, which pushes visual fidelity further using Unreal Engine 5.

Beyond performance, the demo also refines input handling. Both mouse-and-keyboard and gamepad controls have been further adjusted, with expanded customization options and improved menu navigation when using a controller. Support for flight-simulation hardware has also been enhanced through direct Raw Input integration.

The futuristic metropolis of Daevos has received additional visual detailing as well, adding density and atmosphere to the cityscape. These changes aim to make the urban environment feel more alive while preserving the fast-paced aerial combat the game is built around.
