  • optimization
    314 mentions Positive Neutral Negative

    The game's optimization has been a significant point of contention among players, with many reporting severe performance issues, particularly in multiplayer and during intense gameplay scenarios.

Overall, while the game shows promise and can run smoothly on mid-range hardware, it still requires substantial optimization to provide a consistently enjoyable experience.

    • “Rocky start but over the years they fixed every major issue I can think of, improved performance to an insane level and they continue to put in a lot of effort, thought, and work into this game.”

However, there are concerns about the game's advertising and the need for better promotion to reach a wider audience.
