A while ago, NVIDIA released the DLSS 3.5.X update. I realized that it should work for Mount & Blade II: Bannerlord as well, and it offers improved frame rates compared to the old version with fewer artifacts. I personally haven't encountered any artifacts, but they may occur in different configurations. The ghosting issue present in the previous version seems to have been completely resolved. While I don't detect any significant visual differences between the two versions, I'm not a benchmarker, so I'll leave it up to your expertise to assess the performance differences.

I see ~20 FPS boost in exact same configuration in certain scenes. Overall, TW's DLSS implementation within the game isn't the best, so be cautious while using it - it looks blurry in certain scenarios but not too bad to hinder your gameplay. In crowded battles, I did get a good performance myself.

Note:
- This is not a regular mod, you have to install it yourself.
- I didn't try to check if EasyAntiCheat is detecting this as a cheat, so it might not be compatible with Multiplayer
- You OBVIOUSLY need a machine that can run DLSS. 

How to Install:
Download it
Unpack it
Go to Mount & Blade II Bannerlord\bin\Win64_Shipping_Client\  (or Mount & Blade II- Bannerlord\Content\bin\Gaming.Desktop.x64_Shipping_Client if you are GamePass users)
Copy paste nvngx_dlss.dll to here, if it asks to overwrite, say yes.
Done.


This DLSS is a finding I made and extracted from somewhere else. I didn't create the entire .DLL file myself. If you have concerns, don't use it.
