In Progress [1.5.9] Extreme FPS drops on campaign map

[Tulor]

Summary: FPS on the campaign map has fallen dramatically on the campaign map. This is specific to a save file that was started during 1.5.8. FPS while on the campaign map falls to 25 REGARDLESS of video or performance settings. If you hover your mouse over a settlement or a warband (including the players) the FPS instantly shoots back up to 70-90. If you open the game menu the fps shoots back up to 70-90. The FPS drops to 25 regardless of the speed settings including pause.
How to Reproduce: Hover mouse over a city and then move mouse over empty terrain to see the bug take affect.

Hmm, I noticed in my last screenshot that I had one of those super super old invisible tracks popping up. Is this issue related to millions of those tracks being stored?

We have a special performance build to check for these issues by collecting telemetry data. Can you switch to that build, test your performance and send us your data?

1. Switch to “perf_test” from the Steam betas tab. You can find more info about it here.
2. Open the game as usual and proceed to the stage where you are experiencing performance issues.
3. Before the performance issues start, toggle the profiling tool by holding the “right shift” and pressing the “T” key.
4. 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.
5. 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.
6. Finally, upload the file to the "upload.taleworlds.com" site. Please write your username and this threads 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. 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.

Okay MArdA. I went ahead and uploaded the file and some more system information. I'd like to report a bug with the upload page. If you put text in the description box and then click to another tab, or just click outside of the active text input frame, and then click back to the text description box it deletes everything you had written.

I'm getting tracks that are over 5900 hours old with a scouting skill level of 275. The campaign map is down to 10fps, while menus and battles etc are 100+ FPS. I'm wondering if our issues are related in some way. Hovering over tooltips doesn't help the fps though.
