Need More Info Maxed out GPU usage even in main menu

No, I didn't use any mods.


Hi, I have an issue with Bannerlord (vanilla, single player) with respect to overly excessive GPU usage. When running the game the GPU whirrs loudly per HWMonitor it's running at 100% GPU usage when in game. As soon I launch Bannerlord in the main menu (before loading a saved game) the GPU usage hits 70%, despite it only being the main menu. On the world map GPU usage is at 100% all of the time, constantly, and so fans are loud and GPU runs very hot, meanwhile CPU is at 1% utilisation. I have tried reducing the frame rate to 60 which makes a small amount of difference but the GPU fans are still maxed out. All of this happens both full screen and borderless mode. Game is on medium performance settings and I am experiencing these issues, if I reduce graphics performance overall settings to "low" the GPU usage lowers to 60% (but then game looks like something from two decades ago).

My PC is a good spec, all windows updates and latest Nvidia drivers installed (Corsair software also running for LEDs etc). I have not adjusted any Nvidia settings. Why is the game running seemingly entirely on the GPU and not using the CPU?

How to Reproduce: Happens every time when running game

We have a special performance build to check for these issues by collecting telemetry data. With this data, we can see exactly where and when the game's performance issues happened. Switch to “perf_test” from the Steam betas tab. You can find more info about it here.
  • Open the game as usual and proceed to the stage where you are experiencing performance issues.
  • Before the performance issues start, toggle the profiling tool by holding the “right shift” and pressing the “T” key.
  • Record for 20-30 seconds press the toggle key combination again. Please keep in mind that, the more you record, the more upload time it will require.
  • Find the "test.tmcap" file in the "...\Mount & Blade II Bannerlord\bin\Win64_Shipping_Client" folder. You can find the "Mount & Blade II Bannerlord" folder inside the games installation folder.
  • Finally, you can send the file to us via the ticketing system. You can find more info about how to upload files to us with the new ticketing system here.
  • It is appreciated if you provide more information about your PC, what you were doing while the game was recording, and your graphics configuration. If the data you are trying to upload is too big or the site fails to upload, you can use an alternative site to upload your data. If you choose to do that please left a reply to this thread with the download link.
