Curse of Strahd crashing

Hi, Ive just started running curse of Strahd last night and all of my party including myself were experiencing our web browsers crashing or the dynamic lighting re-setting. We have done internet speed checks and it doesn't seem like the issue is on our side, what we have all noticed that our GPU was on 100% when crashes happened. Are there any ways we can try to optimise our browsers or the campaign to not use so much GPU? most of use Chrome and one party member uses Opera. Thanks in advance :)

I had the same thing today when running Curse of Strahd and using the new lighting. Chrome would appear to lock up at times and the lighting would break randomly for players, showing only black.

This might not specifically be a Curse of Strahd problem. Frequent browser crashing has been a problem in my group's homebrew campaign as well. Doesn't seem to happen on any particular page more than the others.
