Oil Grenade and Explosive Grenade Combo

Dear GGG, Fellow Gamers,
I started playing the latest 0.4 league as a Mercenary. I decided to use a crossbow and grenades. Unfortunately, when using the oil grenade and explosive grenade skills, the PlayStation 5 ignites itself, generating a drastic frame rate drop. The fire effect significantly slows down the gameplay. Fighting difficult enemies adds another layer of challenge. The lack of optimization in the PlayStation 5 version, in my opinion, makes some characters unplayable. Still.
Kind regards,
Bartosz

I will not create another thread.
The Dreadnought Arena, which was previously mentioned, suffers from a lack of optimization on PlayStation 5. The large number of enemies in a small space significantly reduces frame rates on the base PlayStation 5 version. Killing Benedictus in the wrong spot on the map (right next to the stairs leading to the arena) prevents the scene with Tavakai, the Chieftain, from triggering. I'm currently waiting for the instance to reset, hoping to push the story to its conclusion.
Fighting bosses with fire offers an extra layer of challenge by significantly reducing frame rates.
The grand promises of optimization in patch 0.4 bypassed the console?
