Performance

Thank you to the players who took the time to report the performance issues with the Demo! We took these reports seriously as soon as we received them and got right to work patching some big issues with frame rate averages and spikes. In this update we are making multiple changes to optimize player and weapon models, the user interface and HUD, and NPC bots.

We have also added a graphic to the Host Server screen that illustrates the performance impact of adding bots to your game. We recommend 5 bots on a mid-range PC. Setting the Bot Fill target to 6 (the default) will make sure you either meet or come in under this number. We aren't going to restrict the number of bots you can add, but we thought it was wise to let you know that running that many virtual brains is not free.

Version b28_2.0 also includes fixes made to the Demo in the first three days. Thanks to our community for reporting these issues on the Discord!

  • Demo Missions progression blockers

  • Issues with the Contest Mode finale sequence

  • Problems with sounds not playing or finishing too late

  • Concerns with UI flow and user experience

Thank you for playing the C4 Demo!

Secret Handshake Interactive is brought to you by players like you.

Thank you.
