Start here

  1. Record the GPU, CPU, memory, display resolution, current game build and the frame-rate target you actually need.
  2. Run one repeatable scene and write down the baseline before changing anything.
  3. Compare Master Quality first, then image reconstruction. A current full-release comparison places those two controls ahead of the remaining quality options for performance impact.
  4. If the GPU supports both paths, compare TSR and DLSS at the same output resolution. Do not compare two different resolutions and call the result a settings win.
  5. Test FX, reflections and Hardware Lumen only after the first comparison. Keep texture quality separate because available VRAM changes that decision.
  6. Repeat the same scene. Keep one change only when the result is clearly better for the stated target.

What the full-release tests can—and cannot—tell us

One independent full-release comparison reports Master Quality as its largest gain outside image reconstruction on an RTX 3080 Ti. Because the accessible article is missing CPU and resolution context, its 91-to-138 FPS observation is useful for ordering the first test only; it is not a portable FPS promise.

A separate full-release benchmark used MSI Afterburner, maximum graphics quality and native rendering at three resolutions. Its published 60-FPS average thresholds show how quickly native maximum quality becomes demanding:

3840×2160GeForce RTX 5090 classNative maximum quality is not a sensible universal target; record reconstruction and Frame Generation separately.

These are third-party full-release observations, not Field Signal testing. Different scenes, patches, drivers and CPUs can change the result.

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 by the official performance page as an optional, high-end lighting workload that needs GPU headroom. The full-release comparison found a smaller hit than during beta testing, but that single test does not make it a default recommendation.

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.
