Performance Issues with Jumpgate

A bigger map of mine, which performs poorly is now (with Jumpgate) nearly unplayable.
Yes we know, big maps with lots of token naturally perform worse.

Question:
The hardware accelleration seem to not work properly on this map.
Smaller Maps with only a fixed maptoken and some creature token get a GPU Usage of 20-30% and 60 fps
The big Map only goes to 10-15% while on around 15-20 fps.

Does anyone know this phenomenon and has some tipps?

Hi Lgs, 

Have you filed a bug report with Roll20 via the Help Center? If not I suggest doing that so that they can investigate the cause. 

not yet, i don't know if that is actually a bug or just some weird occurrence with a perfectly logic explanation.
But will do that now.
