Either stuttering or high input lag, APEX is handling fullscreen badly (PC)

Are they even trying to solve this? This game feels like I'm playing on USA servers from Europe, the worst input lag I ever experienced, just garbage. Sometimes it goes away for like 1 out of 10 matches and I suddenly shred ppl making 3-4 times more dmg. My rig hits the framerate cap 90+% of the time, so that's not the point. I recorded few vids out of curiosity and I can see that f.e. in close shotgun fights, I get the nmy spot on in the middle of the crosshair, but the firing happens several frames later (60 fps vid). This is why you can see some pretty good players on streams struggle and even miss shots on downed enemies, for many players the guns fire so late after the button press, they can just crawl out of the crosshair. When I check something else like quake frame by frame, when the crosshair nails the nmy I pretty much always fire & hit as it's supposed to happen, so the lag is not 'in my hand', I usually fire exactly when I should, when I miss that's simply not being able to track the nmy with the crosshair but still firing some.The devs in apex stuffed the firing full ugly overwhelming effects as they do nowadays to hide hiccups from novice players, but this input lag is so bad it stand out.
