Iron nest: heavy turret simulator system requirements

Minimum Requirements

The official minimum system requirements for IRON NEST: Heavy Turret Simulator are built around a target of an average 30 FPS at 720p on low settings. These are the baseline specs needed to load into the heavy-artillery missions and play through the campaign without hard crashes, though you should expect to make visual compromises on integrated graphics.

• OS: 64-bit processor and operating system
• Processor: Intel Core i5-4460 / AMD FX-8350
• Memory: 4 GB RAM
• Graphics: Intel UHD / AMD Vega 8
• DirectX: Version 10
• Storage: 5 GB available space

The additional notes in the official specs state that a dedicated GPU is recommended for a smoother experience. Performance may vary significantly depending on system configuration and thermal conditions, so a desktop with good cooling will hold closer to the 30 FPS target than a thin laptop with Intel UHD graphics.

Recommended Requirements

For higher resolutions, smoother frame pacing, and more visual detail, the recommended specifications step up to a six-core CPU and a dedicated mid-range GPU. The official recommended tier no longer relies on integrated graphics and gives the artillery simulation room to breathe.

• OS: 64-bit processor and operating system
• Processor: Intel Core i5-8400 / AMD Ryzen 5 2600
• Memory: 8 GB RAM
• Graphics: NVIDIA GTX 1060 6GB / AMD RX 580 8GB
• DirectX: Version 10
• Storage: 5 GB available space

Both recommended GPUs carry 6 GB or 8 GB of VRAM, which gives you room to run at 1080p and keep dense battlefield effects from tanking performance. The 8 GB of system RAM also prevents memory pressure when the artillery calculations and audio cues stack up during long missions. If you already own one of these cards or a comparable newer model, you should be comfortable leaving the game on its higher presets.

System Notes and Performance Targets

IRON NEST targets 30 FPS at 720p on the minimum spec and a smoother, more consistent experience on the recommended spec. Both tiers require a 64-bit operating system and DirectX 10, and the install size stays at 5 GB across both tiers. Since the game is single-player only, there is no online multiplayer bandwidth or server load to factor into your CPU and network performance.

• If you play on a laptop with integrated graphics, expect the frame rate to dip below 30 FPS during heavy smoke or sustained fire, even at 720p low settings.
• Thermal conditions are an official performance factor; clean dust filters and stable fan curves help keep the CPU and GPU off their throttling limits.
• The game supports Steam Cloud, which is useful if you switch between a desktop and a lower-spec portable system, though both machines still need their own storage space for the 5 GB install.
• Because DirectX 10 is the target, older GPUs that support it can still run the game as long as the CPU and RAM meet the floor.

The 30 FPS at 720p target is explicitly stated in the official minimum notes, so set your expectations accordingly. Players who want 1080p or higher should aim for the recommended tier, especially if you want to keep the frame rate stable during the heaviest artillery exchanges. A dedicated GPU makes the largest difference at both spec tiers.
