PC lag when open big files

[True Credit L28999322cwm2]

I have problem when adobe AI open very large file using 20-30GB memory,
It only lags on PC, but works fine on Mac, e.g. zooming in on pictures is slower than 1 second
Is it better to use Adobe AI in Mac than PC? Do other PC users have same problem?

Hello @True Credit L28999322cwm2,

Thanks for reaching out. Depending on various factors like the CPU (Cores/Frequency), the GPU (Available VRAM), and the installed system memory can affect the performance in Illustrator, especially when working in 3D and on large files. It is, therefore, necessary to meet or exceed the recommended system requirements for Illustrator (https://helpx.adobe.com/illustrator/system-requirements.html) in such workflows.

You may also try the suggestions shared in this help article (https://helpx.adobe.com/illustrator/kb/optimize-illustrator-performance.html) to optimize Illustrator's performance and check if it helps.

Looking forward to hearing from you.

Thanks,

Anubhav
