Lag/LowFPS

Hello, first I would like to say that I don’t know what else to do, so I write this topic in search of help.

I can easily play any current game on my computer, however, when I try to join a server in VU, I can barely move my character because of so much lag. I’ve searched on YouTube and here on the forum, I didn’t find the answer. If anyone knows, I’d be grateful. this only happens in VU, it’s impossible to play this way.
