Crashes#

Game crashes to desktop on launch#

Likely causes:

• Fresh Clean Install has just been done.
• Enabled/Disabled mods within Vortex
• Cleared r6/cache

Fix:

This is a common thing that can happen when making mass changes to your cyberpunk directories. The most common fix for this...And you'll never believe me, is a simple PC restart...I know, I didn't believe it at first either. But most Flatline errors are solved by a simple Windows restart cycle.

Crash when fast traveling or loading a save#

Likely cause: A conflict between two mods writing to the same game resource, usually related to world streaming or NPC spawn tables.

Fix:

1. Open the CET console log immediately after the crash (on next launch, it will show the last session's log).
2. Look for [error] lines referencing a specific .archive or .tweak file.
3. Cross-reference that filename against the Issue Viewer — this is one of the most commonly tracked issue types.
4. If unresolved, file a new issue with the log attached.

Mod loading issues#

Mod fails to load in CET#

[error] Failed to load module: <modname>.lua

Likely cause: Version mismatch between the mod and your installed CET build, or a missing dependency the mod expects to already be loaded.

Fix:

1. Confirm your CET version matches the one specified for the current collection release in the Changelog.
2. Confirm the mod in question is still part of the current collection — it may have been replaced or removed in a recent update.
3. Reinstall just that mod's files, ensuring they land in the correct bin/x64/plugins/cyber_engine_tweaks/mods/ subfolder.

ArchiveXL / TweakXL conflicts#

Likely cause: Two mods editing the same .tweak or .xl resource, with load order determining which one "wins."

Fix:

1. Check the collection's load-order.txt (included in the package) and confirm your manager or manual setup matches it exactly.
2. If using Vortex, let it auto-sort using the collection's rules rather than manually reordering plugins.
3. If the conflict persists, it's likely a genuine bug — check the Issue Viewer or file a new report.

Performance issues#

Severe stuttering with the visual bundle enabled#

Likely cause: ReShade preset running effects poorly suited to lower-end GPUs, or shader cache not yet built.

Fix:

1. Let the game run in one dense area for a few minutes uninterrupted on first launch — this allows the shader cache to build; subsequent runs are smoother.
2. If stuttering persists, switch to the "Lite" variant of the collection mentioned in the Changelog.
3. Selectively disable the heaviest ReShade effects (screen-space reflections, ray-traced-style filters) via the ReShade overlay (default hotkey: Home).
