1. Establish a baseline
Restart, use stock clocks, note game and driver versions, and reproduce the issue in the same scene.
Handle shader compilation in Escape from Tarkov
Repeatable diagnosis before random config edits.
2. Work the likely causes
Allow the first-run shader process to finish, avoid interrupting it, and expect temporary traversal stutter after major driver or game updates when caches are rebuilt.
3. Change one variable
Retest after each change. Preserve screenshots of settings and revert changes that do not help.
4. Escalate with evidence
Use official support with crash logs, exact hardware, temperatures, patch version and reproduction steps.
