Hackthebox website slow to load from Virtualbox VM

Hey everyone,
I have a Mac with 8 Gb Ram and I have allowed 3GB ram for the Windos VM. Whenever I open hackthebox website it is extremely slow. I can browse other websites but when it comes to websites with 3d graphics in the background (https://www.hackthebox.eu) it is extremely slow. How can I disable this?

Also website is glitchy. If I click on password text box to enter my password, it takes 10 seconds for the cursor to appear so I can type. Pretty sure it’s due to the graphics in background of the website
