Simulacrum level is ultimate CPU\GPU burner

I know, there are many topics related to Simulacrum balance. But I want to talk about performance of this arena and effects on delirious maps as well.

So, delirious maps have 4 layers of special effects:
1) Fog in the middle covering all actions of enemies
2) Blue mana-siphon like overlay on the ground
3) Mirrors around (seems the worst performance killer, because once they shatter - FPS gets back to almost normal values).
4) Color filter

All those at the same time simply kills FPS from 60 down to 10-15, sometimes 3-5 (when 2 bosses enter arena). I am using GPU Nvidia 3060Ti which is not great at all, but can run most of new games fine, I put all setting to lowest possible and disabled all effects and set dynamic scaling to Performance mode, that's how I manage to keep game running at 50-60 FPS no matter what build I use and how many effects I spam, this works completely fine everywhere, except the delirious maps.

I managed somehow complete tier 1 with 4 deaths, all deaths are from bosses loaded on arena with 2 second lagspike and insta spamming AOE one-shot attacks, can't react on what can't see. All arenas I did simply metodically dancing with roll dodges around arena and shooting my grenades in all directions, killing enemies coming from all directions in small inconsistent waves causing even more FPS drops in moments of spawn. I didn't see how mobs look like, how many of them were there, what moves and appearance bosses had, I simply reacted in 5 FPS on boss HP bars and that's it, I am not even sure what shadow was boss on the arena and what were simple mobs.

This entire run took around 10-15 minutes and my laptop was burning hot, something I can only achieve in 4-5 hours of playing POE2 endgame without restart. It also has terrible effect on eyes and brain, it's very dangerous for people with certain conditions and for human eyes in general.

Please, tune down the amout of effects for deliriuos maps, especially Simulacrum, there's no point in covering enemies in super effects, enemies already strong and insidious in this encounter, difficulty is already enough to keep players thinking before cover maps with delirium "buffs" and entering Simulacrum unprepared. Color filter could be lighter, fog and illusory mobs are probably fine, but mana pool effect is pointless, mirrors are cool design, but amount of them should be much smaller, effects should be cheaper or allower to be disabled\diminished on will in settings.

Thank you!

P.S. And the worst part - the reward sucks, uniques I dropped are usable max for Act 1, but somehow dropped from level 80 encounter, no good resources, except mid-tier emotions I am dropping same way from natural delirious maps. So much pain and no reward. Unfair...
