The Ilustrator program alows me to work only with simple, primitive files. If an artwork has effects, patterns, brushes ans so on I can`t work with it. Drag and drop of objects and some other functions in the attached file are very slow. The computer is quite powerful, the characteristics are in the screenshot. We also attach a video of how the problem manifests itself
thank you for attaching the screens with the features of your computer and a video demonstration of the problem. However, we need more information to help you. Which version of Adobe Illustrator are you using? Have you checked if there are any updates available for your computer? Have you tried to reset the software preferences?
Reset settings to default - did not help
AI version - 26.0.1 64 bit
