If your Total War: Three Kingdoms is crashing immediately after the Sega logo (or during the intro videos), it is almost always caused by a video playback issue, a mod conflict from a previous update, or a DirectX conflict.
Here is the step-by-step checklist to fix it, ranked from most likely to least likely.
Steam Beta Branch Method:
1.7.1_previous or launcher_previous if available.steamapps\common\Total War THREE KINGDOMS\ → right‑click Three_Kingdoms.exe → Properties → Compatibility → tick Run this program as an administrator.Total War THREE KINGDOMS folder to your antivirus exclusions list (Windows Defender → Virus & threat protection → Exclusions).Following the "Shadow of the Sand" patch in late 2024, the DX12 implementation in TW:3K became unstable on RTX 40-series and Radeon RX 7000-series cards. The SEGA logo crash is frequently the engine choking on DX12 ray-tracing requests that don't exist.
The Fix:
-dx11If that doesn't work, try -gfx_enable gfx_render_dx11 as a launch command.
Even disabled mods can cause crashes.
