Apex Legends FPSLAG all of a sudden, was fine before [ Edited ]

[Cynicalic]

So two days ago my Apex legends was working perfectly. I've been playing for about 500 hours without any troubles at all. The game WAS smooth and I had a very enjoyable time. But yesterday I had a windows update and after that update my drivers for AMD GPU were removed for some reason so I had to reinstall a fresh version of the newest drivers too.

My first issue was lagging when moving the mouse, I tried setting Mouse polling to 500 but that didn't help as some had said so I looked around more but nothing. I then sat it to 125hz and now the mouse stuttering is gone thank god. But one issue still remains, my game is FPS lagging. I usually have around 70-90 FPS when in the dropship but it has never lagged even though I'm on a 144hz, always been smooth as a babies butt. Now it's insanely laggy and when I drop to the ground it's also laggy as hell, playable? Yeah maybe, fun? No. It seems like my avg FPS has dropped down. I have not changed any settings, I have the best FPS settings in game possible.

I don't know if it has anything to do with Origin because Origin itself is kind of laggy all of a sudden and lags up my computer and I've tried reinstalling it but it didn't help.

And as said it has all worked fine until two days ago I've tried so much but to no avail. Yesterday I had a few games that worked perfectly fine, 7/10 were lagging but after a few restarts on apex it worked again. But today it's totally unplayable. I've been sitting here for 5 hours straight trying to find a solution.
