As in the title: I'm having severe problems with the Waterdeep: Dungeon of the Mad Mage module that I've paid a total of $100 for (50 for the book, 50 for the pre-built module in roll20), especially when it comes to using it in tandem with the features my Roll20 subscription pays for. Having read troubleshooting threads to gain a general understanding of how we're supposed to optimize our own games, I've determined that it's because the maps are pathetically optimized, especially for their huge size. Me and my players are suffering because 'looking pretty' was prioritized over 'actually running smoothly'. Level 3 is a good example to pick at, because the map is so huge it intensifies the other problems. Keep in mind: If this 50 dollar package was being sold as an artwork, rather than as a mechanical aid for running an adventure module, these would be points in its favor. -The map itself is very high res. One might say 'stupidly' high res, considering that the map is all but a black and white wireframe, rather than having any graphical details to worry about rendering properly. It looks very nice, but to achieve that 'sharp' look it uses *several* map tiles, all of which are fairly high-resolution image files instead of one moderately-high-res background tile. -Whoever made the Dynamic Lighting elements was clearly either paranoid or unfamiliar with the toolset. They use a lot of small, individual line segments instead of freeform shapes. To my understanding, R20 counts and renders each of these separately- and since nobody but the DM uses them, it doesn't matter if things like the dividers in area one are a bit scribbly, or just have one line each, or are left un-DL'd. This is something I'll have to spend even more of my time correcting. -Similarly, many pillars that are too small to provide obscurement in any circumstance are ALSO given Dynamic Lighting lines! Sure, it might make it look pretty and show off your lovely system, but I literally cannot use it unless I delete all of these. -More Dynamic Lighting problems: The ROCKS/natural pillars in the RIVER AREA of level 3 are given Dynamic Lighting lines! This area isn't even going to be traversed very heavily by the players, much less have combat. This is just bloat; nobody but the DM will even see it, but Roll20 still has to handle it! -Removing the above reduced the lag of a 'quick drag and drop' from about 5-6 seconds to about 1 second. Still bad, but I'm not willing to merge and lower the resolution of a massive pile of map assets. -The grid is.. Small, for some reason? Again going back to trying to shoehorn in the super-rez maps instead of lowering their resolution. Smaller grid -> more lag.
