Larian Studios Forums Baldur's Gate III Baldur's Gate III - Technical & Gameplay Problems Help! The game was running smooth until today

So, I've been playing since launch with no trouble, other than Act 3's textures taking a while to load, but no lag or crashing. I've been putting off updating my computer to the latest windows 10 update, but decided to go ahead and do it last night. All of the sudden, my game is lagging really bad today. My current playthrough is in act 2, and the textures are taking even longer to load than they were in act 3 previously. The lag is also bad, all the animations get jittery and the sound cuts in and out. I've had it lag so bad it freezes. I've also had it crash while loading a save. I'm trying to figure out what's causing this all of a sudden but the only thing that's changed was me updating my computer.

Things I've tried to do to troubleshoot:
-Making sure my driver's were up to date-- They did need an update (one literally released today), but the update did nothing to fix my issues
-Updating the game-- I hadn't updated the Minthara hotfix yet, but once again this did nothing to help
-Launching the game from the .exe file instead of from the launcher-- This has helped a little, the game will typically run smoothly for a period of time (it's not consistent), then it'll lag, and then if I close it and re-open it again from the .exe file itself it usually will run smoothly again for awhile. And I'm specifically choosing the dxll .exe since I've never played with vulcan before

I don't want to turn the settings down as I was able to run it just fine before on it's current settings.

Does anyone have any ideas on what would cause this sudden change or how to fix it?

Thank you for any help you can give!

I'm having a similar problem in Act 1. I'm guessing that's Patch 3 preparations and I'm also waiting for the Patch to hopefully be applied today before I continue playing.

I am still experiencing this issue after patch 3. I cannot figure out what is causing this.

Here are the other things I've tried:

-Lowering the settings to low: did nothing
-Turning on slow HDD: did nothing
-Turning off dynamic crowds: did nothing
-Verifying game files: did nothing
-Clearing the level cache files: did nothing

When I initially made this post, I was playing a character in act 2. Now I'm trying to return to my character in act 3 but the lag is making the game unplayable. I've been trying to monitor the game in task manager, but as I never had to do that before I don't have anything to compare it to.

In the game's current laggy state, typically CPU usage is at 20%, memory fluctuates between 80-90%, and disk usage is around 50%. The memory is the thing that stands out the most to me, but it's not like memory leak where restarting or reloading the game fixes things. I thought this was the case at first, but now that I'm testing the game in act 3 it is laggy from the moment my save game loads up to the moment I exit.

I could accept it's a hardware issue if my game hadn't been running lag free, even in Act 3, for over a month. I did not change anything on my computer between the time I exited the game on the 21st and began experiencing severe lag on the 22nd except update Windows 10. Why am I having this issue all of the sudden? Did anyone else start getting lag after the September Windows 10 update?
