I've recently returned to GW2 after several years away, and I'm running it on a brand new desktop PC.
The specs on my computer are: Intel Core i7-7700, GeForce GTX 1080 Ti, 16 GB DDR4 2666 MHz. I'm also running the game from an SSD.
I tested my FPS on Heaven Benchmark 4.0 on highest possible settings @ 2560x1440 and got ~80-100 fps on most scenes, occasionally dropping down to a steady 60-70 fps on some more intense scenes.
However, when running GW2 I sometimes randomly start getting really low fps (30-40), even personal story instances and fractals. I could understand it if I only got fps drops during massive world event bosses or similar situations, but a lot of the time during world event bosses I have a solid 80+ fps.
Any help with fixing this would be appreciated, as this is really frustrating.
