Preview terms

Updated October 10, 2026. NoLag is currently offered here as a free preview source download. This website does not accept payments.

What is provided

The download contains Python source, setup instructions, and tests. It is not a signed Windows installer. Check the setup guide for requirements, verification limits, and known limitations.

Performance and system changes

Performance improvements are not guaranteed. Results depend on the game, hardware, connection, and measurement conditions. Review actions before applying them. Some controls need administrator access. Supported preferences have exact restoration backups; advanced legacy controls may restore defaults, and cleanup is irreversible.

Third-party tools

Optional tools such as PresentMon are supplied separately by their providers and are subject to their own terms. NoLag is not affiliated with hardware manufacturers or game publishers.

Paid plans and refunds

Listed paid tiers are planned offerings. No paid license can be purchased here yet, so there are currently no purchases to refund. Final plan entitlements, license terms, refund policy, seller details will be published before checkout opens.

Support
