Spawning lots of mobs / Mob floor trails causing immense lag?

Now, my system is somewhat outdated as I am pushing my GTX1080 to the end of its ability. I am playing the game at as low as possible to ensure I can have steady frames. I also have a i9-9900k CPU. I'm sure I am not using the ideal hardware for the game. Regardless, I have had a blast playing so far and have been enjoying the game.

Now. I'm sure a handful of things are causing me performance issues. One is for certain: spawning in of mobs, as I have lagged in the trial of the Sekhemas as the trial where you pull the lever to start the survive timer nearly always causes my frames to hitch. Also, Breach spawning on maps causes a TON of lag, which I'm sure is due to all the mobs that are spawning and the mobs that "aren't" even spawning, as we now know from the interview this past Sunday.

Other than the spawning issues, the ground trail effects from mobs, specifically the most egregious of these being the lightning ground effect trail, cause a LOT of lag for me.

Obviously, I will continue to have performance issues until I upgrade. But, it would be great if these could be fixed so I could have a better experience. Hopefully, if some of these problems I face get fixed, there might be more considerable performance improvements for most players.
