[HAMSAILY]

If you are using an NVIDIA RTX 30 or 40-series graphics card, pay close attention to your rendering speed after every driver update. NVIDIA often introduces new memory management policies—such as the controversial Sysmem Fallback—which can unintentionally choke older or previous-generation cards, causing severe performance drops in AI generation. To unlock the raw, unrestricted power of your GPU, it is highly recommended to completely wipe your current drivers using DDU (Display Driver Uninstaller) and roll back to proven, ultra-stable releases like Studio Driver 552.22 or (THEY RECOMMENDED 566.36)

Please, try this experiment yourself and reply with your findings! I have tested it personally and was absolutely shocked by the massive jump in speed, especially when running heavy models like Flux, Z-IMAGE ,FLUX.2 Klein 9b 4B , KERA 2 .
