Is ffx_fsr3_x64.dll safe?

Verdict
Safe

No engine flagged this verified CD PROJEKT DLL, and its signer-matched history, static properties, and completed sandbox run provide consistent benign evidence.

All 74 antivirus engines left the DLL unflagged, including 17 high-trust engines, and its CD PROJEKT S.A. signature verifies correctly. Five signer-matched files previously showed the same benign pattern, while one completed sandbox run produced no malicious verdict or offensive-only behavior.

Use with normal care

Keep the file if it belongs to a legitimate CD PROJEKT installation and its signature still verifies. Obtain replacements only through the game's official update or distribution channel.

This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.

Analyst conclusion

All 74 antivirus engines left the DLL unflagged, including 17 high-trust engines, and its CD PROJEKT S.A. signature verifies correctly. Five signer-matched files previously showed the same benign pattern, while one completed sandbox run produced no malicious verdict or offensive-only behavior.

Where this verdict could be wrong2 caveats
  • signing.signerStats.totalSamples=1 is a limited direct history, although 5/5 signer-matched similar files also received prior 'safe' verdicts.
  • contactedHosts=null means no saved host-reputation cross-check is available; however, the completed sandbox recorded no contacted domains, IPs, or URLs.

These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.

Recommended action

Keep the file if it belongs to a legitimate CD PROJEKT installation and its signature still verifies. Obtain replacements only through the game's official update or distribution channel.

7 evidence-based answers
Is ffx_fsr3_x64.dll safe?
Evidence-based answer
ffx_fsr3_x64.dll appears safe. 0 of 74 antivirus engines flagged it. It carries a verified digital signature from CD PROJEKT S.A.. Use it only as part of software obtained from the developer's official site or another source you independently trust.
What is ffx_fsr3_x64.dll?
Evidence-based answer
ffx_fsr3_x64.dll is a Windows library or loadable module, about 160 KB. Our analysis did not identify a verdict-driving threat signal. It carries a verified digital signature from CD PROJEKT S.A.. A file's name can be reused by different files, so we identify it by its cryptographic hash (below).
How many antivirus engines detected ffx_fsr3_x64.dll?
Evidence-based answer
None — 0 of 74 antivirus engines flagged ffx_fsr3_x64.dll. That's reassuring, though it is not proof that a file is safe, so we also weigh its behaviour, identity, and reputation.
Is ffx_fsr3_x64.dll digitally signed?
Evidence-based answer
Yes — ffx_fsr3_x64.dll carries a valid digital signature from CD PROJEKT S.A., which confirms the file hasn't been tampered with since that publisher signed it. A valid signature is a positive signal, but note that malware is occasionally signed with stolen or abused certificates, so it isn't proof of safety on its own.
What is the SHA-256 hash of ffx_fsr3_x64.dll?
Evidence-based answer
The SHA-256 hash of ffx_fsr3_x64.dll is 042e083248869e106059e0d08a753dc29ce82122096cbd2a582127c83ab2a793, and its MD5 is 103269e0ed8a72b8959427277647c983. This hash is the file's unique fingerprint — two files with the same SHA-256 are identical. Use it to confirm you're looking at exactly this file (not just one with the same name) when comparing against antivirus databases or a download's published checksum.
Is it safe to use ffx_fsr3_x64.dll?
Evidence-based answer
Based on the recorded evidence, ffx_fsr3_x64.dll has a low observed risk and is properly signed. The important caveat is source: make sure you downloaded it from the official website or a trusted store, because attackers sometimes distribute malware-laced copies under a legitimate file's name. If your own antivirus flags it, verify the source and the exact hash before overriding the warning.
How up to date is this analysis of ffx_fsr3_x64.dll?
Evidence-based answer
This report reflects the scan run on September 23, 2026. Because a file's hash never changes, the identity of ffx_fsr3_x64.dll is fixed — but antivirus coverage improves over time, so a file that looks clean today can pick up detections later (and vice-versa). If you need the latest picture, MalwareTips staff can re-run the analysis from scratch.
