Re: How to get stable FPS with my config [Lenovo Legion Y520-15IKBN]

From my first match I have fallen in love with Apex Legends. After a while I understood that in this game speed, smoothness and high precision in ultra fast combat style is so important. So I started to think about making the game run as smooth as possible, tried some cfgs, some changes in videoconfig.txt to make my game run more smoothly and maybe I broke smth because before I started to make those changes I didn't check my FPS and I think that game was running better (also after I started doing those changes I cannot switch Model Detail from Low to any other option)....
After then whatever graphics I put i cannot find balance. My FPS ranges from 140 FPS to 30 FPS. Checked by NZXT CAM and some other software, also I checked in game ovelray (origin) and ofc I see that sometimes there are some drops.
I would love to have stable 60 FPS at least. I hope it is possible with my laptop. What may cause those drops? What may I do to fix it. (don't tell me things like "reinstall plz...") I hope some1 will help me with my problem.
FPS drops are almost always when I am entering buildings

PS: Game is at HDD I'll change it to SSD tomorrow and one more thing that when I play CPU and GPU temperatures are pretty high. from 50 to even 90 celsius. Also I'll attempt to clean system from malware and other crap.

PS2: I run Windows 10 and all my drivers are up to date.
