Thanks for the info. No idea why it might be struggling – it runs smoothly for me on much older hardware!

In a way I'm not surprised – and yet, I'm unable to replicate the problem. Out of interest, what browser are you using, and do you perhaps have gpu hardware acceleration turned off?

Thanks for that! Should now be fixed :)

Your work is awesome and the site is brilliant. Nice job sir.
