Choppy Framerate on Grineer Forest and Infested Galleon

[NeoRetro10K]

When 18.5 hit, you truly optimized the graphics - everything looked better, yet ran so much more smoothly. However, the update immediately after that made Earth missions and certain Infested nodes (noticeably when Grineer Galleons become Infested) unplayable with how much the framerate slows down. Nowhere else has this problem.

Every update since has also slowed down these tilesets even more, and furthermore, I suspect the Halloween update also has a (probably unrelated) memory leak, as it takes twice as much memory as it did before, according to my Task Manager. Also, as other recent threads have pointed out, the special effects on Earth right now aren't helping its already-previously-reduced framerate.
