Extreme performance issues since patch 1.5

[jamie.lachance]

Hi, I'm posting here because I've seen this issue reported in many places but found no fixes. I don't see a report on it here either. Since patch 1.5 has gone live, I've been experiencing extreme stuttering and outright freezes to the point where the game is unplayable. Some have reported an improvement after updating their graphics card or reinstalling it. Neither has worked for me.

Here is what I've found after some testing:

1. When I start and load a save, the game works perfectly for 1-2 minutes.

2. Then the game freezes for 10 or so seconds.

3. I then have massive frame drops for the next several minutes.

4. After about 10 minutes of gameplay, performance seems to return to normal.

I've also got this exact same issue, even down to the game running fine for a minute or two, then freezing for several seconds, then frame time spikes and stuttering like crazy afterwards.

I'm on Windows 11, with a 7800x3d and a 5080.

EDIT: I'm playing on Gamepass and I've seen others on Reddit talking about this same issue who are also on Gamepass, while those on Steam don't have it.
