Please fix performance of explosions and improve the design for ground effects and on death effects

The FPS performance of the game goes out the window when playing explosions builds.

I'm playing explosive grenades, because, if I switch to gas grenades as the main skill I have to wait a couple of seconds or more for the FPS to get to normal.

Even so, I have to enable FSR and dynamic resolution to keep the game responsive (so I can move around and try to dodge somewhat) when exploding like 5-10 grenades.
These explosions degrades the visuals of the game so much that I basically can`t distinguish anything on the screen anymore, until the "smoke" and some of the ground effects from the grenades go away and resolution goes back up.
Because of the dynamic resolution going down to try to keep the FPS to 60 and FSR
blurring everything, I can`t see anything - burning ground, chilled ground (shocked ground is somewhat more perceivable because it`s blue) and especially can`t see the on death effects.

The only on death/ground effect that appears to stand out is the effect of "Exploding nearby corpses" because of the growing golden shiny shell around the corpse (don`t know how to describe it) and the sun-like rays coming out of it.

Please fix the performance of the explosions and please design better the ground and on death effects so they are better communicated to the player.

Add better sound queues, make the ground effects stand out more and make them distinguishable from player skill effects.

I know a lot of players would argue to take them out of the game, but I'm not asking for that in any way. I ask to fix the performance issue and to make ground and on death effects clear for the players to see/hear.
