DLSS 5 Swapper Not Working: Find the Failed Step

Start with the symptom

What do you see?

Choose the first thing that goes wrong. Change one thing at a time and keep the result.

Prefer the written checklist?

F8 does not open the overlay

1. Check the route, API and bitness. The compact F8 overlay requires documented x64 DX11/DX12 Feeder or RenoDX v4.7 conditions. Multipass uses Home. Other APIs cannot be diagnosed by F8 alone.
2. Keep Swapper running and check the configured hotkey. A closed app, remapped hotkey or preview panel is different from a connected in-game overlay. Check the add-on-capable ReShade build and connection status.

The game crashes

1. Save diagnostics, then restore originals. Close the game before restoration. If the restored game also crashes, isolate that baseline before blaming the new route.
2. Compare the actual EXE, API and existing loaders. Use one route at a time. Check other injectors and overlays, then compare one change against the working baseline.

Effects or a DLL are missing

1. Read the exact missing filename and selected route. Native DLSS and Feeder do not need identical files. A generic no-effects message is not a reason to fetch a DLL from an unrelated site.
2. Check the completed install and matching component paths. Inspect the log and the expected effects/add-on paths. Obtain matched files through the official project workflow; stop if the package or checksum differs.

The overlay opens, but nothing changes

1. Separate a visible panel from a loaded consumer. Check the component list and log. Swapper's preview panel, a slider moving or GPU load increasing does not prove the game completed a neural pass.
2. Check inputs and compare the same scene. Native games need the expected DLSS setting; Feeder needs usable depth or motion inputs. Keep camera and settings fixed for an enabled/disabled comparison.
3. Record the driver and changed components. A newer-driver warning is not a universal cause. Save the exact versions and diagnostic status instead of repeatedly stacking components.

The game slows down or runs hotter

1. Compare one repeatable scene against the baseline. Record resolution, settings, GPU, driver, consumer and frame time. Neural processing and generated-frame counters measure different things.
2. Change one setting and measure again. Try fewer passes or the relevant quality controls, then compare frame time, image quality and response. Keep a change only if it improves your repeatable result.

Install fails or the app will not open

1. Separate application startup from game installation. For startup, verify the official Windows x64 package and the exact security alert. For installation, confirm the actual game executable and close the game.
2. Read the final log and the denied path. EPERM can identify a protected folder. An Installed message before completion is insufficient; use the release's documented permissions advice for that path.

Save a configuration record

Record Swapper version, game build, GPU, driver, rendering API, executable path and bitness, selected route, and known component versions. Include existing mods and overlays. Capture the exact error rather than replacing it with “not working.”

The project documentation describes Save diagnostics. Save that bundle before reinstalling or restoring so the failed configuration remains available for investigation. Review logs before sharing; remove personal paths and account information.

Follow the first failing row

What you observe	Check next	Where to continue
Application will not launch	Official package, Windows x64 requirements, specific alert	Download and source checks
Install ends with an error	Target EXE, folder access, completion log	Installation checks below
Game crashes at launch or during play	Whether the restored game works	Crash isolation
F8 or controls do not connect	Hotkey, process, route, API, add-on	Overlay checks
No effects or a missing DLL	Native versus Feeder route; exact filename	Missing-file diagnosis
Components load but image is wrong or unchanged	Inputs, consumer, model, runtime evaluation	Rendering checks below
Image works but the game slows down	Fixed-scene comparison and processing cost	Performance measurement

Did installation finish in the right place?

A launcher and the rendering executable may live in different folders. Confirm the actual target and the game’s active API. If a game changes between DirectX and Vulkan, the installed route may no longer match.

For EPERM, read which location could not be written. The v2.2.7 notes explain the protected-folder permission message and fix an earlier premature installation-success message. A status shown before the operation finishes is insufficient evidence.

Close the game before repairing an installation. Follow the first-use sequence and keep the restore files. Do not repeatedly layer new routes over a failed one.

Did the right consumer load?

Check the component list and log. The ordinary native / Feeder consumer and Multipass consumer differ. If the ordinary native route was installed with v2.2.5, v2.2.6 corrected an incorrect consumer; the affected game requires the documented reinstall, not only a desktop update.

For a non-native game, validate Feeder’s inputs. For a native game, check its DLSS setting. A panel appearing, a configuration value reading back, or GPU activity increasing does not by itself establish a completed neural pass.

If the image flickers or changes incorrectly

Compare the same scene with the effect disabled and enabled, then check the selected consumer and input data. If flicker starts only after installing a route or adding a pass, return to the previous configuration before changing another component. For Silent Hill 2 Remake, record the game build and whether flicker also occurs without Swapper; these checks help isolate the problem but do not establish a game-specific fix.

Avoid treating warnings as universal causes

Driver 616.56 is the publisher’s last measured neural-pass baseline in this release. The newer-driver message is a warning that still permits installation. It is not proof that every later driver fails. Likewise, one issue report involving an overlay or an injector does not explain every crash.

Change one variable at a time and keep each result. If the evidence remains inconclusive, the useful outcome is a reproducible report with an exact failing stage, not an unsupported universal fix.

Return to a working game

Save diagnostics, close the game, and choose Restore originals. Verify normal launch and the baseline scene. Follow complete restoration if application removal is also intended. If the restored game still fails, investigate that baseline before another injection attempt.
