Do you copy ip and connect via console or straight from site? Use console.
I am having same problem but on DM-FFA servers, and sometimes on faceit.
Sometimes it get fixed when i mess with rates and bandwidth settings in csgo but after some time it get back.
I suspect its my internet but i dont get it why, mm is working fine, 50/5 internet speed.
And for example BrutalCS servers on which i have like 70 ping is not stuttering but on Official FFA with 30-40 ping has stuttering (everything you said its same, teleporting me back few seconds,etc.)
I set my power settings to high in my pc and it fixed lags in both esea and faceit, worth a shot.
It could be the server that you are connecting to?
Stupid new windows 10 update!!!!
When i run csgo and go to windows and in the game again, the stupid game load so slow.

contact faceit support, if mm works its not a problem in your client. maybe a routing issue?
