Quick Answer
The Wuthering Waves anti-cheat error on an RX 9070 XT is a software conflict, not a faulty card. Run the game as administrator, update to the latest AMD Adrenalin driver, and disable conflicting overlays or virtualisation features (memory integrity / Hyper-V) and the error clears in the large majority of cases. The RX 9070 XT itself is fully compatible.
Fix the anti-cheat error step by step
Start with the cheap fixes that resolve most reports. Right-click the launcher and Run as administrator so the anti-cheat can load its kernel driver properly. Update to the newest AMD Adrenalin driver, since anti-cheat systems sometimes flag older signed drivers. Then turn off Windows Core Isolation / Memory Integrity temporarily, disable Hyper-V and any virtual machine platform, and exit overlays such as capture or monitoring tools that hook the game. Verify the game files through the launcher to repair a corrupt anti-cheat install before reinstalling anything.
When it is the system, not the game
If the error persists, look wider. A pending Windows update or a clock that is out of sync can break the anti-cheat handshake, so update Windows and set the time to sync automatically. Aggressive antivirus suites sometimes quarantine anti-cheat files - add the game folder as an exception. The RX 9070 XT, with its 16GB of VRAM, has no compatibility issue here, so if you are also troubleshooting performance, that is a separate matter from the anti-cheat handshake. Buying your card from Evetech means a clean warranty path if you ever do suspect a genuine hardware fault.
FAQ
Is the RX 9070 XT compatible with Wuthering Waves?
Yes - the RX 9070 XT runs Wuthering Waves without hardware issues. Anti-cheat errors are driver or Windows configuration conflicts, not a GPU compatibility problem.
Why does Run as administrator fix the anti-cheat error?
Anti-cheat systems load a low-level driver that needs elevated permissions. Running the launcher as administrator lets it initialise correctly, which clears the most common version of this error.
Could memory integrity be blocking the anti-cheat?
Yes - Windows Core Isolation / Memory Integrity and Hyper-V can interfere with kernel-level anti-cheat. Temporarily disabling them is a frequent fix when other steps fail.
