I understand why you think its the case about particles overwhelming your machine but you're on space shuttle compared to mine 2080 Super with i7-9700K.
Now, to be honest, when I watched your recent video posted in your original thread, this literally reminds me of the common AMD stuttering which I experienced on my own, even in Windows OS you can feel it when doing some basic tasks and getting that stutter. I imagine a person would need to first get used to the Intel PC build to notice it as someone who might be buying their first PC and going with AMD wouldn't be able to determine the unacceptability of those stutters. But that's beating around the bush, lets try to nail this down for you.
I can recommend; as your FPS is pretty solid and just occasionally drops to ~90, to go with these options for a test. Edit the video.txt file located at similar path as mine shown
bolded below.
The lines starting with // are commented out and won't be in use until you delete // but I added it for you just in case you might wanna test those options as well.
The particle options are what you might want to try out. Low latency setting might also help, let me know your current value regardless of what you put. I think by default game has it on 1. You can also set it to 0 which could stop the stuttering on its own.
D:\SteamLibrary\steamapps\common\Deadlock\game\citadel\cfg
XML:
"setting.r_low_latency" "2"
// "setting.volume_fog_width" "16"
// "setting.volume_fog_height" "16"
// "setting.volume_fog_depth" "16"
// "setting.csm_max_shadow_dist_override" "1024.000000"
"setting.r_particle_depth_feathering" "false"
"setting.cl_particle_fallback_base" "3"
"setting.cl_particle_fallback_multiplier" "3.000000"
When you save the file, go to properties and make it Read Only, otherwise game might overwrite it if you change settings in game or on patch / update.
