Many players of Captain of Industry have reported that the Steam Overlay combined with recent NVIDIA drivers causes hard, unpredictable DirectX/Unity crashes. Open your Steam Library. Right-click Captain of Industry and select Properties. Under the General tab, toggle off "Enable the Steam Overlay while in-game". Disable Hardware-Accelerated GPU Scheduling (HAGS): This Windows feature can occasionally mismanage VRAM spikes in heavy simulation games. Go to Windows Settings -> System -> Display -> Graphics -> Change default graphics settings and toggle Hardware-accelerated GPU scheduling to Off. Restart your PC. NVIDIA Power Management: Open the NVIDIA Control Panel -> Manage 3D Settings. Under the Global settings, find Power management mode and switch it from Normal to Prefer maximum performance. This prevents your RTX 4070 from dropping its voltage aggressively during simulation ticks. Cap your Frame Rate: Do not let your RTX 4070 run at uncapped FPS, as this spikes the engine's frame statistics. Lock your FPS to your monitor's exact refresh rate (e.g., 60Hz or 144Hz) in the game settings or via the NVIDIA Control Panel. Switch to Borderless Windowed: Ensure your in-game display mode is set to Borderless Windowed. If the game window drops focus or has a timing glitch in Exclusive Fullscreen, the Unity DX11 swapchain will break immediately. Captain of Industry relies heavily on the CPU-to-GPU data pipeline. Even if your RAM overclock/XMP profile works fine in other games, Unity simulation games can easily trigger memory access violations (Poging om toegang te verkrijgen tot ongeldig adres) if the RAM timing is even slightly unstable.Try temporarily turning off XMP / EXPO in your motherboard BIOS to see if the game stabilizes.
