Updated - Randomly dropping to 1 FPS

I am playing Tri ele Cyclone of tumult, the only solution I found is to not hold cyclone the whole fight and only attack for half a second at a time. May be an issue with cylone or steam proton version (im playing on linux mint).

I tried playing on lock step, predictive and adaptive.
I have turned off all MTX and it still happens.

PC specs:
GPU: Radeon 5700XT
CPU: Ryzen 5 2600
RAM: DDR4 16gb 3200 speed
OS: Linux Mint

UPDATE: Switched to Direct X12 and the game worked smoothly for 1 map and then crashed my whole PC and now the game does not launch. I verified intengrity of files and it still does not launch.

Got the game to launch.

I also updated my drivers.

the issue still persists and is actually more prevalent now, i cant run more than 1 map without it happening. please help, the game is unplayable like this.

quick video i made. I can replicate the issue. If i restart the game it happens on the second map i run.

I have tried a lot of variations of settings and this variation in the video is the only one that lets me complete at least one map before the issue occurs.
The issue started happening when i switched to cyclone from boneshatter and was very rare, not the issue is happening every map or every other map if i restart the game.

UPDATE: I tried different skills and everything seemed fine until i decided to finally use frostblades, specced into +1 targeting enemies mastery, got 20/20 frostblades. and using them a single time in a big pack of monsters caused the same issue. no idea what the underlying cause is. If its my CPU then i would experience issues in other games but i dont.

Same thing same hardware, except I have rx 580 8gb and cachyos. I run ritual and blighted maps and every map fps drops to 1 and latency to ~999. And I don't even use any of my skills (siege ballista), just only towers. Tried a lot of settings to change, no difference. It started from this league. Once I've decided to wait and do not close the game, just remained standing (because of safety towers layout), slowly due to mobs became less, fps came back. But obvious its impossible in rituals. Just one more thing - my sensors of GPU show me low load and temperature at those moments.

I guess I figured out. I've changed Networking mode to Predictive and now it plays smoothly


p.s. Nope....It still happening. But less often

Running into this issue as well. Running CF + Explode build and whenever I hit any big pack of mobs the game drops to 1 fps and logs me out.

Same as OP, usually 1st map works fine then it starts happening. Literally unplayable.

Edit: Removing my Asenath's gloves seems to fix this issue for me. I had them with double corrupt implicit for vulnerability on hit and maximum life in case this helps pinpoint the issue.
Removing them is a downgrade for me but at least I can play now
