FPS drop to 10

Hi All,

Having issues for few days now (since Wednesday). FPS is really low, grapic loades really slow, I can't move my mouse without having a slow motion like experience. Sometimes it looks like it starts with FPS around 50 then drops to 10 within seconds.

Attaching screenshot from the training area (FPS=10) - the same happens on usual maps as well - DxDiag, MsInfo.

No issues when playing other games. Drivers up to date.

Thought this might be similar to the below topic and tried most of the suggested steps https://answers.ea.com/t5/Technical-Issues/100-CPU-usage-troubleshooting-steps/m-p/10707752#M133286.

• If you're using an Nvidia graphics card, try updating the drivers using the Express method. Then, launch the game from the GeForce Experience.
• Use the Windows System File checker or a new Windows profile: https://answers.ea.com//t5/Bug-Reports/CPU-usage-100-all-the-time/td-p/10689953
• It's possible this is related to Windows Defender. These instructions may help.

Also tried:

• launching with advanced options and inputting "-novid -high +fps_max 0 -nojoy" per YT instructions (https://www.youtube.com/watch?v=f99f5ys1nBs).
• turning off fullscreen optimization for r5apex.exe
• setting graphic prefereneces on Windows level to High Efficency for Apex
• re-installing the game
• removing temp files
• lowering graphic settings within the game
• Removing Easy Anti Cheat and repairing  (https://answers.ea.com/t5/Technical-Issues/Apex-Legends-FPS-Instability-Problem/m-p/8172907/highlight/true#M50844)
