Hi guys,

I hope someone can help. I'm really struggling with an issue I have using PoL for League of Legends - there is a very consistent stutter for about 100ms every 5 seconds that I can't get rid of no matter what I am doing in game. The game runs on full graphics settings at 60fps, but drops down to 40fps for that split second. The ONLY thing that makes it better (although still there) is to turn 'allow flipping' off in the nvidia-settings control panel.

I have tried so many different things just from googling around but now I'm completely stuck and so sick of trying to fix it. Things I've tried include different drivers, setting gpu clocks to max performance, turning composition off, changing commit times on /etc/fstab (I thought it was hard drive related), setting cpu governor to max-performance, even trying ubuntu (which I know is not that much different under the hood but a different desktop environment I think?). There doesn't appear to be any issues in /var/log/Xorg.0.log.

I can run glxgears no problem at ~15,000 fps, or 60fps with vsync on. No stutter whatsoever. However, when PoL is running, then glxgears is also affected by the stutter produced. The thing that made me suspicious about it being linux commiting to hard drive was jbd2/sdb2 was jumping to the top of iolist every time a stutter occurred - precisely every 5 seconds, although turning journaling off on the hard drive had no effect, so now I'm back to square 1,

Help please!!

Wow, this is a strange problem.  So its only happening when running Wine related programs/games?

Does it ever happen with other things like Internet, Steam, etc?

I love typing this. lol. :\

FULL computer specs? Distro? Architecture? You forgot to post up some extremely important information. Also, post up those logs and anything like that, instead of just describing it. It helps a great deal more to have concise information, rather than a description of what seems to be a complicated issue on a computer that could have any combination of hardware and software. 

Also, please don't use exclamation points. It is like yelling, and doesn't get questions answered any faster. ;)

Hi guys,

Sorry for the late reply - I've had more important things than gaming recently.

My computer specs are - 2500k @ 4ghz, z77 sabertooth, 8gb RAM, nvidia gtx770

I have now found the issue happens in a native version of KerbalSpaceProgram, so it doesn't appear to be wine related. Kernels I have tried in Mint are 3.13.0-37 and 3.16.0-34 (I am using the latter now because it resolves a keyboard issue). I have tried ubuntu 14.10 on a different hard disk and still had the same issue (I can't give a kernel version for that, sorry - it's whatever it comes with by default).

Is there any other logs that would be of use, or anything I could run to assist you otherwise?

Thanks

I see you are using Nvidia 331 drivers

(II) NVIDIA GLX Module  331.113  Mon Dec  1 20:24:35 PST 2014

have you tried updating the drivers?

Yes, I have tried the latest from the nvidia website (349.16) and also many different 'edgers' drivers. Nothing helps :(

Please read the wiki thoroughly. ;) We need your debug output from POL...

Also, most "edgers" driver PPA's and whatnot will focus on open-source drivers, and with Nvidia, the open-source ones don't cut it. 

One of the most important things, besides your POL debug output, is; did you install the 32-bit libs for your graphics card? That will matter.

As usual, we are just guessing without the POL debug logs, so there is no point in speculation until we know that the 32-bit proprietary libs are installed correctly and we see the POL debug logs (in tools -> playonlinux debugger). I wish I had I could be more concise. haha. :D

When installed the driver off the nvidia website I had definitely installed the 32bit compatability libs and it made no difference. I am not sure if they are installed with this installation,

5. GnuTLS error: A TLS fatal alert has been received.

So, that GnuTLS error can't be good. I have never seen that. First thing I would try to correct would be the p11-kit error. I don't think that is causing the issue, but for posterity, let us try:

http://wiki.playonlinux.com/index.php/Troubleshooting_Common_Problems#p11-kit:_couldn.27t_load_module:_...

As for the Nvidia drivers, it looks as though the 32-bit libraries are installed (you will get errors in the logs that show errors related to missing 32-bit libraries. They throw a fit. lol.). Though, I prefer to always use the official Nvidia drivers from their site (installing the 32-bit libraries is required for almost all software you will run through Wine, so it is best to have it installed anyway). 

As for the TLS thing; do you have a 32-bit version of libgnutls26 or libgnutls28 installed on your system (if you haven't already, install multiarch-support from your distro's repository (using Mint or Ubuntu))? That will likely be needed, as well. Those are things I would check.

Is there a chance League of Legends is running in a 64-bit virtual drive?

There shouldn't be. The script creates a 32-bit one. 

Ok, good, just checking.  I have always used 32-bit for everything as well

Yeah. Plus, a lot of components in Install Components get grumpy with 64-bit (last time I checked. I never had good luck with 64-bit wine running anything.).

I am having the same exact issue.  Frame rate in league drops from 60 to about 40 every 5 seconds exactly then pops right back up but is a very noticeable stutter in the game.

I forgot to mention I also run 3 monitors all hooked up to the 750 TI and play in windowed 1920x1080 mode (main monitor is 2560x1440).

With the debug log running, I get the same repeating errors over and over pretty much in sync with the stutters:

fixme:wbemprox:client_security_Release 0x7d48ad6c
fixme:win:EnumDisplayDevicesW ((null),0,0x9ccdfc8,0x00000000), stub!

fixme:wbemprox:client_security_SetBlanket 0x7d48ad6c, 0x50fc0408, 10, 0, (null), 3, 3, (nil), 0x00000000

Every 5 seconds these 4 lines repeat so it must be related?

Thanks,
Aaron

Ran:

sudo apt-get install p11-kit:i386

to get rid of the pkcs shared library error.

Also, edited /etc/pulseaudio/daemon.conf and set this:

default-fragments = 5
default-fragment-size-msec = 2

to get rid of alsa underrun errors.

Alas, still getting the stuttering every 5 with these same 4 lines:

fixme:wbemprox:client_security_SetBlanket 0x7d5ded6c, 0x50cac0e0, 10, 0, (null), 3, 3, (nil), 0x00000000
fixme:wbemprox:client_security_Release 0x7d5ded6c
fixme:win:EnumDisplayDevicesW ((null),0,0x9ccdfc8,0x00000000), stub!
fixme:wbemprox:enum_class_object_Next timeout not supported

Thank you bouki for posting.  This confirms that it probably isn't a hardware problem, unless you have the exact same hardware as Offbeatdrizzle.... which I really doubt.

Good job applying 32-bit libraries and elminiating the Alsa underrun errors.  Those will definitely help your performance.

I doubt those errors are related, mostly because they are a "fixme:" instead of "err:"
can you post the entired debug from PlayOnLinux?

This is a very strange problem.  Maybe I'll have to install LoL again to check it out

Here is a full debug for this stutter problem:

http://pastebin.com/5it2D1NE

The debug includes launching the game, logging in, creating a custom game, then running around for 2 mins with the stuttering every 5 seconds.

I know you say the fixme are not likely the problem, but I play in windowed mode and can see the debug messages appear as I am playing and these messages appear exactly in sync with the stuttering.

If they are not the cause of the problem, then they are definitely a symptom of the problem.  They are related for sure because the timing is too perfect.

The OP also had a 700 series geforce.  Anyone else running a newer (700 series) nvidia can replicate?

All suggestions welcome!

Aaron
