FAF Client uses extreme amounts of CPU

[Rikai]

I recently lost a game because my PC was slowing down to below 1 fps.
I was wondering what is happening, because this happens occasionally.

While ingame, the taskmanager was still unsuspicious. But when I looked at it again after the game, I found that the downlord's client is using 90-100% cpu.

Closing the client "solved" the problem, as expected. But since I experience this occasionally I wanna get to the root of the Problem.
The client was running for around 10 hours at the time that the bug occurred. PC for the same amount of time.

Newsflash:
It got worse. And stuff building up is not the cause!

I'm currently using the RC7 of the soon-to-be-released 1.0.0 update. (So a different version than in the original post)

I just had an episode where I noticed my PC running weirdly slow for no reason. I suspected the faf client. Which indeed was the cause.

Then something new happened: After around 3 minutes or so of slowdown, the CPU load suddenly vanished:

.

I kept the client open. It still used an absurd amount of RAM (863mb).
---
Then, after another 3 minutes of everything running fine, the CPU load spiked again.

I watched it in Taskmanger for a couple of seconds (maybe 15 seconds). Then the spike was gone again.
Because the client just crashed.
It terminated without error message. If I had been ingame, I would have been disconnected, since the game cannot operate without the client being open.



Since "fine" and "broken" switched in a matter of minutes between 98% CPU load and 0% load, I can deduce that "stuff building up in the background" (as Gorton suggested) is not the case.

Clanmates suggested a reinstall. Problem is: That is already a reinstall. I Installed the RC7 to a different SSD than the 0.10.7.
So reinstalling the client is proven to not solve anything.

Here is another downlords-faf-client.log:

The ice adapter will keep running when the client crashes (unless it sends a termination request to the adapter will crashing).

Your issue is being investigated.

Looks like OutOfMemoryException, tho it was not logged but might be that fatal Errors don't get logged. Never tried that...

I know I also notice that this happens in RC7 and release is hold back for that reason...

I can also reproduce it locally and 24% of memory is used by Texts which seems to much so probably some Ui is not cleared up and builds up in the background

@Rikai
Did you use the "Table" view or the "Tiles" option in Play tab in 0.10.7 ?

[Rikai]

Table. Why does it matter?

[Katharsas]

Because the Tiles view could maybe have a memory leak. Searching for ladder causes high CPU load btw. is that the cause for this?

[Rikai]

No. It happens at random times. Ladder search puts my CPU at around 30% with some waving around (25% to 35%).
Aside from that, the bug only happened outside of ladder search so far. Ingame or while doing normal PC stuff. Not while searching.

[Rikai]

probably some Ui is not cleared up and builds up in the background

Would that UI buildup not lead to a slow buildup of CPU load?
Instead we have a sudden spike that stays at around 100% for a random amount of time. (At the time of opening the thread, I thought it would never go away. was about 10 minutes before I lost my nerve and closed the client. At the next time, it suddenly vanished after maybe 3-5 minutes.)
