Hey RATSHAKERs,

We're now packaging compiled shaders for DX11 & SM5 with RATSHAKER.

Unreal Engine 5, does not do this by default, but this should resolve the error message for RATSHAKERs attempting to run the game on hardware below the minimum spec. Please let us know if this is the case in the following steam discussion thread:
https://gtm.you1.cn/app/3290710/discussions/0/594010406470551968/


This does not mean the game will run well (or work properly)!
You may experience strange behaviour, missing models, broken lighting etc.
We are not able to provide technical support for hardware below our minimum stated specifications.

We've also identified an issue that causes the RAT to "stutter" when screaming. This occurs when the framerate of the game goes above 60fps. It seems the screaming rat logic is not framerate independent, like it should be (and the rest of the game is). We're looking into this and will let you know when a fix is issued. In the meantime, you can prevent this behaviour by enabling vsync & forcing the refresh rate to be 60fps.

Finally, the Christmas update has now been disabled. We hope you enjoyed your present from the RAT.

Please restart steam to ensure you get this update!

Thank you for playing RATSHAKER!
Keep shaking that RAT! 🐀

Hey RATSHAKERs,

We've just issued a fix for an issue introduced in the last patch that caused the instructions in the field to not show in some circumstances (due to a corrupted font :steamsad)

Hey RATSHAKERs,

• Set light draw distances to prevent visual popping.
  
• Disabled unnecessary ticking and collisions on non-interactive light meshes for improved performance.
  
• Removed Steam Audio as it was unused and consuming CPU resources.
  
• Rendering Optimizations:
  
• Adjusted post-process shaders to render before the tonemapper for a significant performance boost.
  
• Changed anti-aliasing method from TSR to TAA and reduced internal render percentage to 50%, maintaining visual fidelity.
  
• Disabled unused visual features such as depth of field, volumetric clouds, and reflections to improve performance.
  
• Locked graphical settings to medium for consistent quality across devices.

• Implemented missing gamepad inputs for rat interactions. Steam Deck and gamepads are now supported for gameplay, though UI prompts for controllers are pending future updates.

• Fixed floating door in the field house.
  
• Corrected instructional text clipping by scaling text dynamically (font size may vary).
  
• Resolved memory leak in cursed objects; idle vibration temporarily disabled.
  
• Replaced a broken sink on Floor 3 with a working one.
  
• Fixed missing audio attenuation for flies.
  
• Fixed sink and bath textures for proper fill appearance.
  
• Fixed overlapping toilet placement.
  
• Fixed an odd wall alignment in the bathroom.
  
• Omitted a checkpoint for the Floor 3 door to streamline progression.

• Adjusted popup instructions to support longer translations without clipping.
  
• Confirmed translation files are up-to-date and functional.
