Cat Mail Co System Requirements

Cat Mail Co targets accessibility with modest hardware demands, making it playable on older gaming PCs and budget laptops. Maracas Studio lists the following minimum specifications for the Windows PC release on Steam:

• OS: Windows 10 64-bit or Windows 11 64-bit
• Processor: Intel Core i5-3330 3.0 GHz or AMD FX-8300 3.3 GHz
• Memory: 8 GB RAM
• Graphics: NVIDIA GeForce GTX 950 or AMD Radeon HD 7970
• Storage: 4 GB available space
• Additional: Dedicated GPU required — integrated graphics not supported

The 4 GB installation footprint is remarkably small compared to modern AAA titles. If your PC has a dedicated GPU from the GTX 900 series or equivalent AMD card with 8 GB of system memory, you should meet the minimum bar comfortably.

Cat Mail Co uses physics-based parcel handling with real-time object interactions throughout the post office. Multiple packages can be stacked, collide, and respond to player placement simultaneously. This physics workload demands a dedicated graphics card with its own VRAM.

Players relying on Intel HD Graphics or AMD integrated solutions will likely encounter startup failures or severe performance issues. Before purchasing, verify your system has a discrete GPU. Laptop users should check whether their machine switches between integrated and dedicated graphics — force the dedicated card for Cat Mail Co in your graphics driver settings.

While official recommended specs beyond minimum are not published, community testing during the Steam Next Fest demo suggests a GTX 1050 Ti or newer with 8–16 GB RAM delivers a smooth 60 FPS experience at default settings on desktop. The game's cozy pacing means even 40 FPS on Steam Deck feels perfectly playable.

For the best visual experience, keep MSAA enabled on desktop hardware that can handle it. Steam Deck users should disable MSAA and avoid downscale resolution for sharper parcel edges. Lower graphical settings have minimal impact on the charming art style while significantly improving frame stability during busy sorting sessions with many physics objects active.

Cat Mail Co runs on Steam Deck through Proton 10.0-4, though the review build required manually forcing Proton 10 to boot. Expect a stable 40 FPS with MSAA disabled and downscale resolution unchecked. Battery life is solid thanks to the game's modest GPU demands and slow-paced gameplay loop.

Controller support was not available at launch, but the default Keyboard (WASD) + Mouse template works well. Map the Q or F key to a paddle for stamp mode access. Text readability on the Deck display is generally good. Read our Controls guide for Steam Deck-specific binding advice and our Review for a broader performance assessment.

On Windows, open Task Manager and check the Performance tab for your GPU name. If it lists Intel UHD or similar integrated graphics without a dedicated NVIDIA or AMD entry, your system likely does not meet requirements. You can also search your GPU model against the GTX 950 performance benchmark — cards equal or newer should qualify.

Try the free Steam demo before buying the full game. The demo uses identical system requirements and provides a risk-free way to test compatibility. Demo progress transfers automatically to the retail version if you decide to purchase.
