Babylon lagging

Hello guys, I have problems with perfomace. On some browsers the babylon is very smooth and fast but on some browsers it lags too much. I tried to use Chrome on different PCs and sometimes 10 fps sometimes 60 though the PCs’ perfomance is not much different. What could cause this problem? Thank you.

This is impossible to answer, just too may variables.

onboard intel graphics or something vs having a card?

Johns right though, there are a million factors to consider and we don’t have enough info.
