Halo: Campaign Evolved – Release Notes

Global 

• Cinematics may occasionally stutter during playback if the display refresh rate is not an even multiple of 30 Hz. 
  • Workaround: If possible, set your display refresh rate to a multiple of 30 Hz (such as 60 Hz, 120 Hz, or 240hz), turn on Game Mode on your TV if available, or turn off Variable Refresh Rate (VRR), as it may contribute to cinematic stuttering on some setups. 
• Audio and video may become out of sync, and the cinematic can briefly freeze, if the game is paused and then resumed during a cinematic. 
• Navigation markers do not progress until everyone in the Fireteam passes them. 
• After the first generator in Two Betrayals, players will be unable to progress if they destroy the banshee. 
• While playing The Truth and Reconciliation, you may hear brief popping or stuttering of audio during gameplay.  

XBOX 

• Suspending the game during a cinematic may cause the last frame shown before suspension to remain on screen and overlap subsequent cinematics for the rest of the playthrough. 
  • If this occurs, fully restart your console to restore cinematics to normal.  

PC 

• Launching Halo: Campaign Evolved directly from the HaloCampaignEvolved.exe file in the Steam installation folder may cause the game to launch without connecting to Steam. When this occurs, you may be unable to sign in, experience severe performance issues, or encounter a game freeze that requires the application to be closed through Task Manager. 
  • Workaround: Launch Halo: Campaign Evolved directly from the Steam library within the Steam app itself. 
• Some Intel 13th and 14th generation processors may crash on launch due to a pre-existing Intel microcode issue that can prevent affected systems from successfully starting certain applications.
  • Players who have not updated their BIOS recently may be affected. If the game closes or crashes before reaching the splash screen, install the latest BIOS update available from your system or motherboard manufacturer. 
• AMD graphics cards using driver versions 26.6.2 or 26.6.4 will likely crash when skipping the introduction cinematic in the mission The Maw while FSR is turned on. Watching the cinematic to completion can reduce the likelihood of a crash.  
  • Workaround: Change your upscaling technique to DLSS, XeSS, or TSR, turn on Frame Generation while using FSR, or roll back to driver version 26.6.1.
• AMD graphics cards may crash when using high refresh rate displays if VSync is turned on and the maximum frame rate is set to 30.  
  • Workaround: Raise the maximum frame rate limit, or disable VSync. 
• Players using the Low upscaling quality option for DLSS upscaling may notice visual grain, haze, or oversized lens flares when using Low graphics quality settings. 
• NVIDIA RTX 50 series graphics cards may crash on missions Keyes and The Maw when using driver versions 610.47, 610.62, and 610.74. 
  • Workaround: Update your NVIDIA driver to 610.88, or rollback to 596.49. 
• Turning on XeSS Frame Generation while an in-game maximum frame rate limit is set can cause the game to become visually frozen, with only occasional frame updates. 
  • Workaround: Use FSR or DLSS with Frame Generation instead of XeSS, turn off Frame Generation when using XeSS, or remove the in-game maximum frame rate limit. 
• Using Frame Generation with XeSS upscaling may cause graphical issues and limit frame rates during cinematics. 
  • Workaround: Use Frame Generation with DLSS or FSR, or disable Frame Generation while using XeSS.
