Hello,
Please switch to perf_test branch on Steam and follow these instructions to help us identify the issue:
Open the game as usual and proceed to the stage where there are performance issues. Before the performance issues start, toggle the profiling tool by holding “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 Steam’s application library folder. Finally, upload the file to the
http://upload.taleworlds.com site. Please write your username and this thread's URL into the description box so that we can find it easier. It is appreciated if you provide more information about your PC, what you were doing while the game was recording and your graphics configuration.
Thanks.
