Choose features by constraint

  • TSR and DLSS: the official performance page presents both as image-reconstruction options. The correct choice depends on supported hardware, output resolution and the result you measure.
  • Frame Generation: officially supported on compatible NVIDIA GeForce RTX 40-series cards and newer. The same source warns that a low base frame rate can increase input latency.
  • Hardware Lumen: described as an optional, high-end lighting workload that needs GPU headroom. It is not a default recommendation for every PC.

If a setting does not persist after relaunch

The current official launch thread has acknowledged settings-persistence problems, but it does not authorise deleting configuration files, editing .ini files, changing permissions or disabling cloud saves. Keep the recovery check reversible:

  1. Record the platform, current build and the original setting.
  2. Change one setting and apply it through the visible game interface.
  3. Relaunch once and compare the displayed value with the record.
  4. If it reverted, restore the original value and stop stacking local changes.
  5. Recheck the current official thread, then report the platform, build, original value, tested value and relaunch result.

When to stop tuning

Keep a change only when the repeated run is meaningfully better for your stated goal and does not introduce a worse tradeoff. Undo unclear results. After a game, driver or operating-system update, start a new row rather than averaging unlike builds.
