If I skip all the mobs and run directly to the “quest encounter” in monoliths, the game gets extremely laggy. From 144 fps to less than 10 fps. The more mobs I leave alive and the more visual effects they use (for example those water shields drop fps insanely), the faster the fps drops to unplayable.
I’ve tried this on 3 different builds now and this happens every time, tested both on medium and very low settings. I think you guys keep rendering the mobs we “activate/see” and never deactivate them. I suggest doing what PoE does = only render ~2-3 screens worth of radius around our character, and if we aggro a mob and then run out of that radius, it stops rendering.
