I have 200 hours in Elden Ring on PC, and I am completely aware of the rough PC performance. I expect the odd stutter every now and then, but it's still more than playable on my system. However, out of no where yesterday, I started getting complete freezes that last about a second every 30-45 seconds. It drops to under 30FPS. This is something totally new. I get little stutters all the time in this game, but nothing like this. Below are the things I've done to improve performance in the game, and to try to fix this massive freezing issue:
Turned off Easy Anti-Cheat.
Set GPU power to "prefer maximum performance" in the Nvidia control panel.
Turned threaded optimization on in the Nvidia control panel.
Set FPS limit to 59FPS in-game.
Set the game to "High Performance" in Windows settings.
Set Steam to "High performance" in Windows settings.
Disabled the Xbox app.
Disabled Steam overlay.
Reinstalled the game.
Verified integrity of game files.
Tried windowed borderless & full-screen.
Temperatures are all good across the board.
What else can I try?
