Summary: DayZ crashes immediately on launch (before main menu) when "Smooth Movement" is enabled. The game starts normally only when this option is disabled. Crash occurs on official servers. Steps to reproduce (100% repeatable): 1. Launch DayZ with launch parameter "-dx11" (no other flags). 2. Attempt to join an official server. 3. "Smooth Movement" option is enabled in gameplay settings. 4. Game crashes within seconds of launch (often before reaching the main menu or character selection). 5. Error log contains "Access Violation. Illegal write" and [D3D11CoreCreateDevice] stack trace. Expected result: Game launches successfully and remains stable with "Smooth Movement" enabled. Actual result: Unhandled exception crash immediately on launch. Environment: - OS: Windows 10 22H2 - GPU: RTX 5060 Ti - CPU: Ryzen 5600 - RAM: [32 GB - Driver version:617.42 - DayZ version: 1.30.164078.38
What has been tried: - Launch parameter "-dx11" only (removed all other flags like cpuCount, exThreads). - Clean driver reinstall with "Clean Installation" option. - Verified game files in Steam (100% integrity). - Disabled Steam Overlay, Discord overlay, and NVIDIA Freestyle filters. - Reset NVIDIA 3D settings for DayZ to defaults. - Deleted DayZ.cfg and DayZProfile.xml to reset settings. - Ran Windows Memory Diagnostic (result: [OK / errors found]). - Tested without any mods (vanilla game). Additional info: Multiple players report similar crashes with the same error pattern in Steam discussions. This strongly indicates a potential issue with the "Smooth Movement" mechanic interacting with DirectX 11 initialization on certain GPU configurations.
