Is it happening on all the servers for you? I noticed same issue when devs patched to 1.7.2.
But for me it's only happening on battle servers.
TDM, siege, skirmish and captain seems fine.
Sometimes I could play few maps in a row without memory leak happening and sometimes after just 2-3 rounds my ram usage would be at 12+gb
 
Not absolutely certain, but it usually happens after several minutes of play, so skirmish and captain are too short.
I have not seen the problem in TDM, but It also happens on siege.
 
Previously I stated that this issue isn't happening for me on tdm/siege/skirmish/captain servers.
If this person is having problems on siege I guess I would too. Just want to say it so its easier for devs to find the problem.
I only played like 3 siege matches and 2 captain ones after the patch.
TDM and skirmish I spend hours. No problem there(for me at least).
 
We have a special performance build to check for these issues by collecting telemetry data. With that 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 also use the "perf_test_beta" for the most current beta build-related issues. 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.
