For launchers, start with the Ultra preset, keep patchable resources outside the protected region, and publish the protected binary through the release channel after smoke testing.

This kept our patcher stable while still protecting the command and integrity checks.

For launchers with frequent patches, keep the patch manifest, download transport, and replaceable resources outside the virtualized region. Protect the compact logic that verifies the signed manifest, checks the expected file hash, applies channel eligibility, and authorizes the final handoff.
This keeps normal patch generation predictable while making a simple bypass less useful. Test both stable and beta channels, interrupted downloads, rollback, a modified manifest, an incorrect hash, and an update created by an older launcher. Record the protection profile beside each release so a compatibility regression can be traced to an exact configuration.

Measure the launcher before and after protection using the same update package. Useful checks include cold startup, manifest verification time, patch application time, peak memory, output hash, and recovery after a cancelled update.
If performance moves outside the release budget, do not remove all protection immediately. First reduce the protected boundary, then move repeated parsing or hashing work outside the VM, and keep only the final security-sensitive decision protected. This usually preserves the part an attacker wants to patch without placing the complete update workload inside the interpreter.
