CPU High Usage | DSX Official Server | Page 1

It can reach to 10-15% for R5 9600x, and it looks like not the limit for DSX since my CPU was running at 100%.
It goes normal just after unplugging the controller then reconnecting it. Any fix?

Can you send log files and your profiles?
Also you use DSEdge with OC?

brittle tangle Jan 21, 2025, 3:55 PM

#

Yeah I use DSEdge, and sorry what is OC? I will upload log files and profiles together when I counter this issue next time. Thanks!

Overclock

brittle tangle Jan 21, 2025, 4:01 PM

#

Umm probablay not. Never heard I can OC a controller before. I primarily use cable to connect the controller to my PC.

#

The polling rate is 999Hz for sure, according to device info

#

I just found out I have 3 1GB size log files, maybe it correlate with the issue. I can't open them since they are too large. However I found a 230MB log file. The content is repeated for one thing. Here's the scrshot

#

#

#

Do I need to open another thread for this?

#

Sorry I didn't reveal full text for previous pic

gloomy ice Jan 21, 2025, 4:12 PM

#

Weird. I think you cal leave it here
Without creating another thread

#

Just send this log files via Discord if you had nitro or with Google drive

#

and send public link

brittle tangle Jan 21, 2025, 4:19 PM

#

I compressed them now their size are small

Hi I got high CPU usage situation again. I am not playing game, just back my room and found this

#

Here's the log

@granite owl @stark wedge
Do you have any ideas?

brittle tangle Feb 3, 2025, 11:43 AM

#

Get this crazy usage again

#

this time the log looks a bit different

#

📎 dsx-20250203.7z

#

I'm not playing games, and my controller connected through Bluetooth before then it's in idle.

celest fern Feb 3, 2025, 1:27 PM

#

Haha, holy shit

#

Yeah something is hung in an infinite loop, trying things again and again with no grace periods or backoff times

#

No wonder the CPU doesn't like that

celest fern Feb 3, 2025, 3:53 PM

brittle tangle

@stark wedge this is a fun one to debug

stark wedge Feb 3, 2025, 4:01 PM

#

@brittle tangle I need to know your controller details

#

Getting feature reports for Motion calibration has been annoying

#

@brittle tangle In controllers page under home page, show me the device information plz

#

Need to compare our edges to see the difference

#

fokin 360mb log file

#

jeez

#

@celest fern maybe we need a limit on these logs

#

or have custom sink to not print out identical exceptions over and over

celest fern Feb 3, 2025, 4:06 PM

#

stark wedge <@244890837601878028> maybe we need a limit on these logs

I am more for finding and fixing the root cause 😉 also there should be backoff logic in frequently called paths that may fail and generate this

#

I'm sure we're not the first to encounter this, there has to be something we can reuse

stark wedge Feb 3, 2025, 4:08 PM

#

i mean, HidSharp is only calling the native method, idk how this is even fixable

celest fern Feb 3, 2025, 4:08 PM

#

This function reports error details by calling GetLastError afterwards on failure

#

We need that info to figure it out

stark wedge Feb 3, 2025, 4:09 PM

#

let me re-look at the log

celest fern Feb 3, 2025, 4:10 PM

#

This is the perfect use case for Polly btw

stark wedge Feb 3, 2025, 4:10 PM

#

fokin windows

celest fern Feb 3, 2025, 4:10 PM

#

We already use it for the Web retry stuff

celest fern Feb 3, 2025, 4:10 PM

#

stark wedge fokin windows

Careful, the GetLastError needs to be called IMMEDIATELY after the faulty API

stark wedge Feb 3, 2025, 4:10 PM

#

celest fern Feb 3, 2025, 4:10 PM

#

Any other code in between can overwrite it

stark wedge Feb 3, 2025, 4:11 PM

#

oh, did not know that

#

i show you method in DM

brittle tangle Feb 3, 2025, 4:51 PM

#

stark wedge <@292243243503058944> In controllers page under home page, show me the device in...

Sure

#

stark wedge Feb 3, 2025, 4:53 PM

#

The only difference i can see, is the hardware variation, you have a higher number, meaning you could have in hand revision 2, which could potentially have different firmware behavior

#

Have you tried to remove the device from windows fully, and doing the pairing again?

brittle tangle Feb 3, 2025, 4:55 PM

#

I see. But I haven't tried to remove controller after I set up my PC

#

I can try it

stark wedge Feb 3, 2025, 4:55 PM

#

go to BT settings, and remove device

#

then pair it again

#

close DSX while doing this

brittle tangle Feb 3, 2025, 4:57 PM

#

I just paired the controller as you said

stark wedge Feb 3, 2025, 4:58 PM

#

Run DSX -> go to logs page, and see if there are errors everywhere

brittle tangle Feb 3, 2025, 4:58 PM

#

#

No error messages found

#

Only green and grey

stark wedge Feb 3, 2025, 4:59 PM

#

how about the high CPU usage?

brittle tangle Feb 3, 2025, 5:00 PM

#

Now it's normal. It seems happened randomly

stark wedge Feb 3, 2025, 5:00 PM

#

interesting, so before, everytime you open DSX, you would have high CPU usage right?

brittle tangle Feb 3, 2025, 5:00 PM

#

nah, just sometimes

stark wedge Feb 3, 2025, 5:02 PM

#

I see, currently we’ve updated our code where it would give us the actual error message from windows, so when you get the new beta version, it will help if you still have this issue

#

Let me know if you encounter it again soon, I could send you a private build to get the error information quicker

brittle tangle Feb 3, 2025, 5:03 PM

#

sometimes if I left my controller to turn off, then I back to my PC I found this

brittle tangle Feb 3, 2025, 5:03 PM

#

stark wedge Let me know if you encounter it again soon, I could send you a private build to ...

Thanks a lot, appreciate it

#

Looks like it happened three times while I was playing Helldivers 2 and three times when I was away

brittle tangle Feb 16, 2025, 7:52 AM

#

It happened again

#

#

If I launch DSX, then I get loop every time

#

📎 dsx-20250216.7z

#

It can happen even I didn't connect my controller

#

granite owl Feb 18, 2025, 2:58 PM

#

rlly weird
it's happens only in bt connection or wired too?

brittle tangle Feb 18, 2025, 6:04 PM

#

granite owl rlly weird it's happens only in bt connection or wired too?

It happened in both connection modes l, but I feel they may be different. For bt there’re several times I left my controller in idle and then off and it’s happened. For weird connection it always happens when I was playing games.

stark wedge Feb 18, 2025, 6:08 PM

#

Seems like it’s going in circles finding a device, then discarding it and it opens over and over which consumes resources by the system

celest fern Feb 18, 2025, 8:33 PM

#

Check that code path and make sure you're not doing the famous

catch { /* fucking nothing */ }

brittle tangle Feb 20, 2025, 6:04 AM

#

It happened again. This time the PC are in sleep and it's in wired connection.
