That will create a ticket for a team member to look at. Here on the forums, it's mostly community help. Just as an aside, Lag issues are almost never due to computer specs. I can run Dynamic Lighting with explorer mode on my low-mid Chromebook. Connection is not usually an issue either, unless it is particularly troubled (very low speed, remote location, etc.) It's more likely to be either a coding issue on Roll20's end (often but not always indicated by a sudden large influx of reports), a corrupt or overly large game/map pages, a setting on the user end (browser extension, VPN, incorrect setting on hardware acceleration), or a conflict between roll20 code/servers and a user's individual hardware/software setup. (see last paragraph). Lucky Hero, you seem to have tried a lot of the first line checks. Have you tried toggling hardware acceleration? You may even see benefit (anecdotally) by toggling it twice. Are you seeing a huge spike in CPU usage (like 90%+)? That is a known issue affecting a number of users. If it is this case, I can direct you to a thread and resource for that issue. I generally get huge CPU spikes across the board since my PC is 7, nearly 8, years old and hasn't really had a deep clean (which I imagine could help general performance anyway). I got an email back from the bug report ticket and their solution seems to have helped so far. Turns out it might have been NordVPN threat protection. I'm going to keep an eye on things see if the issue resurfaces while threat protection is turned off and update accordingly.
