Note, please keep these in mind with Update 9.0:

• DX11 is not supported.
  
• Make sure you have at least 6GB of VRAM.
  
• Update your GPU drivers and Windows to the latest version.

We strongly recommend that you tweak your graphics settings after updating to Update 9.0, as our upgrade from UE4 to UE5 has changed how those settings work. Visually, the “Medium” setting in UE5 provides higher quality than the “Epic” setting on UE4. The "High" and "Epic" settings on UE5 fully utilize the power of the modern GPU generation and are not recommended for previous GPU generations.

• Use the Defaults button to run the benchmark.
  
• Tweak your upscaler resolution.
  
• Lower demanding settings such as Global Illumination Quality and Shadows.
  
  • Alternatively, start from Low settings and work your way up.
• If you are using Frame Gen, please keep these in mind:
  
  • Intel Frame Gen is supported from GTX 10XX and newer.
    
  • AMD Frame Gen is supported from RTX 20XX and newer.
    
  • Nvidia Frame Gen is supported from RTX 40XX and newer.
  
  NOTE
  
• On the first launch, textures might temporarily be low quality to prevent hitching.
  
• Wake Simulation is currently not recommended, as it causes PiP scope issues.
  
  
  
  RETURNING PLAYERS
• Save your settings and clear your cache.
  
• Unsubscribe from all Squad workshop mods.
  
• Consider lowering your settings: in UE5, Medium settings provide higher quality than Epic on UE4.
