If that were the case it’d be exposed in 3 seconds and be everywhere online. That’s not happening.

They introduced new graphics properties in this update including Nvidia DLSS. Not to mention the scenes rendered are not the same. It’s not going to be the exact same as before.

Update drivers, adjust settings to you liking. You can’t expect it to be exactly the same every time a new 20+ gig update is introduced.

Not only that the servers are on fire right now and the game is hitting a server constantly in the menu and lobby screen. That’s going to deteriorate performance.

If the game performs significantly worse after drivers and adjustments and after a day or so when everything is actually stable then you’d have to look into an issue.

Right now I don’t see a performance issue other than server problems.
