It works on iPad smoothly... there are no recommended specs. It really depends on your model (Number of parts, mesh complexity, etc) and your monitor resolution. That aside it will run better if you have a proper dedicated GPU (NVidia, AMD, etc). As I explained on other posts, laptops often have an integrated and dedicated GPU and default settings in windows is to use the least powerful. You shall make sure in you GPU control panel to run your preferred browser with the dedicated GPU.

I’m thinking of buying a new and improved computer now. Do you think this computer will be fast enough for Mecabricks to run faster?

Hello. I answered on twitter. It shall be ok for medium size build. GPU is a bit outdated though.

Alright, so I just got the new computer, but I want to swap its GPU. Which graphics card is best recommended for designing Modular Houses-scale LEGO models?
