FSrealWX Pro

Hi,

I've been running FSrealWX Pro for a few years now and I've have a few questions.

I don't know why, but when ever WX Pro downloads the weather it bring Flight Sim's frame rates to a slide show. Is this normal or am I doing something wrong?

What are the best settings for WX Pro to reduce the drag on FS when WX Pro is downloading weather?

Thank you for your time,
Kenny
