Massive fps drop ps5/pc in hight monsters density maps

It seems the cause is there is too many corpses on the ground,
I guess the game still need to keep in memory their stats in case of dead monsters are needed to be revive (necromancer / offering skills) or explode by player or rare mobs.

Bur it cause a massive fps drop , it would be nice to allow players to destroy bodies instead of beeing forced to keep them on the ground and play at 20 fps .

Body explode skills from rare mobs or pkayer could be replace by a random explosion near the mob or the player, damage could be calculate on monster lvl in aera, a chance of higher damage as if it was a magic or rare body monster (something like 60% white, 25% magic 15% rare ).

Walking in a finished map (no effect, no skill used) , covered by corpses , is enough to make fps drop to hell.

So i think it could be a great improvement to be able to remove them, or maybe just keep a small amount of corpses at the current location of the player.

Is the drop permanent or does it happen in burst? I've noticed that sometimes I get a gigantic FPS drop, to the point of freezing, but after around a minute the performance comes back.

And the performance comes back even if I don't reduce the number of monsters, and the corpses stay on the ground.

I actually suspect it's shader compilation. I've found out that GPU usage % drops to almost zero while CPU is 100% when this happens.

In regards of corpses, they use low poly models, they are really cheap to render. It shouldn't really be a problem for a PS5.

Not permanent, it's a massive drop when there is tons of corpses, and performance can comes back if there is a clean space in the map. But juiced map means tons of mobs every where..! :)
I don't think it's caused by models on the ground, but more by the stats keep in memory for each corpses (max life , damages , resistances) , as each corpse could be use to be explode / revive .. Even if 95% of the time corpses are useless.

Running a map where corpses are destroyed ( like with the chaos shrine) is really much smoother, no fps drops, as smooth as in campain where there is not many mobs on screen than in maps .
