NS2 build 276 : Bug report

I'm getting this same sorta bug - but only when I resize to a lower resolution after the game is already loaded.

My comp is below minimum specs, so when it's acting sluggish I'll usually switch down from 1080p to 720p. Since the new patch, sometimes when I do this, the scaling on the map doesn't carry over (i.e. the map too big for the screen). The menu elements also become too big, like in this video.

I think the opposite also happens sometimes - if I switch from 720p to 1080p, sometimes the map becomes too small. Never seen it effect the menu in that regard though, although I've had no reason to go to the menu when this happens (often when the map becomes too big from shifting down the resolution, I try to go into menu to change the graphics settings back, only to realise I can't click on options as it's below the bottom of the screen - whereas a small map from shifting up the resolution doesn't bother me so much).

@d0ped0g Only ever run in fullscreen. You can press Alt + Enter to swap back and forth

^^^ Just checked this - I am running in fullscreen.

Since the update my FPS has dropped drastically. I used to be able to run 1900x1200 @ ~100 FPS (low quality settings). Now I get ~40 FPS running 1440x900 (still low quality settings). The effect is more pronounced while in battle, where my FPS drops to 30 FPS or lower without fail. This is on an nvidia GTX465.

In addition to the drastic FPS drop, the game occasionally crashes while making a graphics call:

[460214.011422] ns2_linux32[28317]: segfault at 18 ip 00000000f3b48b07 sp 00000000ff9e9d00 error 4 in libGL.so.340.93[f3afe000+b6000]

The game was so stable for so long that I had stopped running it with core dumps enabled. I'll re-enable those to try to get a stacktrace.

I've found one way to partially remedy the FPS drop I am experiencing. The update seems to have added an "Atmospheric Density" option and it defaulted to it's maximum setting. I had assumed that the slider was meaningless since I had the boolean option disabled. Low and behold, turning the density slider to it's minimum setting boosted my FPS back to a steady ~65 FPS, though it still drops down to ~40 FPS in battle

As the person who added the atmospheric slider I can tell you that in vanilla the boolean toggle overrides the slider.

This crash happened on the IBIS server at 2015-10-25 16:53 UTC. I was in a gorge tunnel as a skulk. FPS was jumping around like crazy just before the screen went black while the core file was dumped. By "crazy" I mean jumping from ~60 FPS to <1 FPS in Observation on Descent. I hopped into the gorge tunnel to see how the FPS would change and then it crashed.

Well completely deleting "~/.config/Natural Selection 2" and then resetting all graphics settings back to low except leaving resolution at the native 1900x1200 let me play a game @ ~120 FPS, dipping to ~90 FPS in battle.

This doesn't seem directly related to the segfault crashes but unsettling never the less:

/media/bulk/Steam/SteamApps/common/Natural Selection 2/ns2_linux32: symbol lookup error: /media/games-ia32/Natural Selection 2/libSpark_Core.so: undefined symbol: _ZN3tbb8internal24concurrent_queue_base_v818internal_push_moveEPKv

The that comes from my terminal when launching NS2 from the command line -- not from log.txt.

This crash happened while in Hydroponics on Biodome, again on the IBIS server. This time as a marine with a machine gun, about to build an RT.

Try another server and see if it helps?
Mods and mixes of mods can cause all kinds of weird stuff. So its always nice to test a different mixture.

IronHorse · October 2015

@eyeris Try running with medium textures and see if you encounter the same results.

Supposedly those backtraces are generally caused around the same time OpenGL is no longer able to allocate memory. (probably from high textures)

Our linux dev, computerquip has spent months trying to fix that specific issue.

Edit: looking through your old comments, your ram was reported at 16041 Mb for some reason?? How much ram do you currently have? (and I am assuming you're running 64 bit linux)
And if you're still using that 1 GB 460 GTX be sure to set your texture streaming memory in the options to 1 GB.

Yeah, I'm running a vanilla 64-bit debian kernel.

$ uname -a
Linux lukahn 4.2.0-1-amd64 #1 SMP Debian 4.2.3-2 (2015-10-14) x86_64 GNU/Linux

I'm happy to try running with medium quality textures, though both of those crash reports were running with low quality textures. I suppose I could also try running with high quality textures in order to see if the crash happens more often.

I do have the video memory setting configured for my 1 GB graphics card. As I understand it, TCmalloc is for allocating system RAM. Could it be that some server mods (especially on IBIS) are simply causing the memory usage to eclipse the 2GB addressable range? I would normally argue that other users would be seeing it too, but the core file for the SIGABRT where TCmalloc bailed out is almost exactly 2 GB:

$ ls -1s --block-size=1M core.*
2041 core.19409.6
1879 core.2163.11

In case it's helpful, here's the low level details my card:

@eyeris I am sure it is unrelated, but you might want to upgrade your Nvidia drivers to the latest 352.55 anyways.
Thanks for the rest of the info, I'll pass it onto computerquip

I set texture quality to high and I was able to reproduce both crashes within minutes.

Here is the SIGSEGV crash. This was on DMD Dallas 2, in the ready room on Refinery, before I joined a team. In the console, just before the segfault, I found this:

Asraniel · October 2015

There is a theory that this crash is related to some memory usage issue on opengl linux. When opengl runs out of memory, it crashes.
Sadly there is no theory why this actually happens. Developer builds that enable opengl on windows do not see this behaviour, the memory usage on windows with opengl is much lower than on linux. Computerquip has been debugging this issue for quite some time, with no real lead yet.

So any information is good i guess. Like, what exactly do you do to reproduce it. Good and fast repro steps are always important when debugging a problem.

eyeris · October 2015

Well here's a crash that challenges the theory that the SIGABRT bug is caused by running out of memory. Maybe TCmalloc believes it ran out of memory but that can't actually be true here. I'm beginning to suspect that this has something to do with Alt-Tab window switching.

This crash happened right after I launched the game. The main menu appeared. The audio was set too high because I had just been playing Insurgency. I used the key on my keyboard to turn down the volume. That causes the game to lose focus. When I pressed Alt-Tab to switch back to the game window, it crashed with the familiar backtrace. The core file is only 787 MB.

This got me thinking back to my more recent tests, where I was trying to get the game to crash by increasing memory consumption. One of the things each of those crashes has in common is that shortly before (though not always *right* before) I had Alt-Tab switched to a terminal window to run htop to check memory usage.

Alt tabbing should reload all of the texture memory again into VRAM, so I could see the possibility, but to me it would seem more like it is flushing it first and then reloading textures.

Just out of plain curiosity can you report the few lines of text that are spit out in your console / log after typing in f_test

Hm, it seems like its crashing in libawesomium (the webbrowser ingame).
I also found somebody with a similar issue from another game:
https://github.com/Facepunch/garrysmod-issues/issues/417

They recommend preloading the tcmalloc library. Could you try to investigate in that direction?
