New Dynamic Lighting Lags Horribly.

I've seen other posts on this issue, but most of them are from over a year ago. I have a decent GPU (A GTX 1660 Ti) and an Intel Core i5 processer, and yet, the new dynamic lighting system makes the game lag so bad it's unpliable for me, and my players play on laptops so I can't imagine what it would do to their systems. I played with most of the new lighting settings and most of them either slowed it down worse or it did nothing.  However, I switched to the Legacy lighting system and it works just fine and runs really well.  so my question is, Is this a fixable issue, or has the new dynamic lighting system just not worked well so far?  I'm worried that I wont even be able to use the tool I'm paying for, if or when they get rid of the old system. 

Is hardware acceleration turned on in your browser? Is your browser running webgl like it should (UDL uses webgl, LDL does not)? <a href="https://get.webgl.org/" rel="nofollow">https://get.webgl.org/</a>

Webgl is active, and while hardware acceleration was active. I went ahead and tried deactivating it, then reactivating it and strangely that helped.&nbsp;

You don't happen to have Grammarly installed ?

Nope, I do not use Grammarly.&nbsp;

It's not very laggy for the other players. It's only laggy for the GM. If you run the same map as a player you'll see that it's not very bad at all.&nbsp; A few ways I've found reduces lag.&nbsp; Reduce the number of unique dynamic lighting walls. If you're using 4 separate walls to box in a square it's going to be more laggy than 1 continuous wall. Reduce number of tokens on the map with vision (Such as monsters)&nbsp; Reduce the number of light sources on the map (such as from torches) Smaller maps Yes it sucks, Yes Legacy is smoother. No I have no idea what the problem is..&nbsp;

I recently cleaned up my browser so to speak and deleted extensions I no longer used. Regardless it seems to be working better now and did not have a negative effect on my players systems when we tried it out.

For me the problem has been that it works perfectly fine for one of my game groups and does not work at all for the another.&nbsp;

See if you can get them to check their hardware acceleration. It could also be that there are other factors in the other game: number of players, map complexity, if the GM has vision turned on for all NPCs, etc.
