[SOLVED] What about multithreading?

Hello, i have a Bulldozer FX 8120 and Xonotic only use one of the 8 core and i have extreme lag when playing, so will Xonotic will be able to use multi core CPU?

Post rest of setup, especially video card.

Here my spec :
AMD FX-8120
AMD Radeon 6950
8 GB DDR3
That should be enough to run it at max settings no?

Please help us help you by giving more information

Are you experiencing actual lag, (related to your connection to the servers, which is hardly influenced by your system) low framerate or stutters?

Which executable are you using, on which OS?

Since people have successfully run this game on much weaker systems (that includes me), I highly doubt it's single-threadedness that is the problem.

What would be ideal, is to post contents of config.cfg file here (it can be found in xonotic/data). Blind guess would be that some of the settings (relief mapping, decals on models) are just hardcore performance killers, no matter the machine. Eg. I run relief mapping on E8400 + 4850 without issues, but not decals on models, as it causes severe slowdowns.

I'm using xonotic-x64.exe on Windows 7 Pro x64.
I dind't find the config.cg in xonotic/data so i've disabled relief mapping and decals on models and the lags are almost gone but when playing with a lot of bots my framerate get down to 40fps.
What is the decals on models effects?

I vaguely remember things working better at one point by setting the core affinity so that Xonotic only uses one core. I think that can be done in the task manager by right-clicking the process or something. Can you give this a try?

config.cfg can be found in your user directory. To know exactly where, open the console in Xonotic (shift escape) and type which config.cfg

When i type config.cfg i get "config isn't anywhere" and i search in my user folder there is nothing about xonotic.

About the core affinity i don't really see a difference when i chose only one core.
I know that making a game or an application multithread can be really hard especially if the engine is not design to it but it would be awesome to have a fully multithread game because it will make multi core cpu less warm, when only one core is fully used it get warmer than 3-4core at 25%.

CPU is hardly the bottleneck in Xonotic as far as I know, graphics are.

Anyway, this is really weird. Do you type exactly "which config.cfg", and is the exact message you get "config.cfg isn't anywhere" ? (You said "config isn't anywhere"). Can you try the command saveconfig in the same console and tell me what that does?

Oops forget the .cgf sorry here the config.cfg

With your setup you should be able to play with one gazzilion fps. The only thing I can think of is that there is something wrong with the drivers of your videocard.

And btw you should definetely play online, much more fun

try ...

turning off bloom
realtime world lighting (only effects maps that abuse it (like red planet))
shadows



anyways ... you say there is an issue with many bots on the screen at once ...

I believe that the cpu IS the bottleneck when animated models (and particle effects) are involved (and lots of bots = lots of models ...)
try messing around with the model lod ... that should bring down the lags

...

for decals on models ... some map elements are listed as models instead of basic map stuff (like the green crates ... or light fixtures ... or half of xoylent)
apparently there is a bug where when a scorch mark hits one of these models it makes the game lag alot ...

Wait, what? Since when 40fps is too low? Yeah, it should be more on that machine, but a man's eye can't see (on the average) >23fps, so anything >30fps is way fluent, and there is no physical way to see more than your displays refresh rate which is most likely 60Hz (so 60fps).

edit: ok, ok... when the eye got used to a computer screen than it can see around as much as the refresh rate, especially in fast paced games. Either way 40fps is good imho.

Right now we don't really have much information about how your system is performing so can you please follow this thread to run 'The Big Benchmark':
http://forums.xonotic.org/showthread.php?tid=2562

Then we will have some ideas with where your system compares. Here is a list of some results:
http://dev.xonotic.org/projects/3/wiki/H...quirements

tZork posted there a system with a Radeon HD6700 which your system should beat be quite an amount so this is what you should compare with.

- AMD FX-8120
- Stock at 3.1Ghz with turbo boost disable
- 8 core
- 8GB DDR3
- Windows 7 Pro X64
- 64bits
And here the log file of the big benchmark :

  the-big-benchmark.zip (Size: 190.77 KB / Downloads: 2)

To paraphrase your results a little:
OMG: 154
Low: 147
Medium: 133
Normal: 129
High: 117
Ultra: 108
Ultimate: 78

This is some way behind some of the other systems listed in the wiki page I linked too with similar graphics cards, especially with the lower quality settings which would show some sort of processing bottleneck rather than graphics bottleneck. Something is not running very efficiently here. While turning the settings down may seem logical, it doesn't fix anything, its just a workaround.

You may want to have a look through this config thread I made previously, disabling compositing may be a good area to start but some lower level work may also pay off:

Offtopic: The difference between 30-60fps is HUGE. You can absolutely perceive it. And 23fps is abysmal to play. It's less visual perception and more in input response. There's a reason some *serious* gamers still carry around CRT's for the massive refresh rate: because it does make a difference. IMO Yes, 40fps is too low. I really only like playing if I'm getting 80+ consistently.

On topic: I've said this before but Xonotic just seems like a very inefficient game. I'm (obviously, as this thread shows) not the only one that gets less-than-expected performance with this game on a decent rig. But that's not always the case.... very inconsistent issues for some. But it's also only 0.6... so... can't complain too much.

Look at my rig for comparison. At the time I ran Core 2 Duo E8400 + 4850, obviously far weaker system. And results?

That's incredibly odd. Or maybe FX really is THAT bad of a gaming processor, as reviews suggest?

In fact FX are pretty bad with game and software non multi threaded.
And i remember that the E8400 is an excellent CPU.

And i remember that the E8400 is an excellent CPU.

Rather good, but close to 5 years old. Your 1 year old CPU should beat it even on a single core, clock cycle to clock cycle basis. In addition, the FPS gradient across the detail levels does not appear a pure CPU limit. If it was a pure CPU limit then all the detail levels would give the same FPS. The gradient is fairly weak which would point at a CPU related limit but not a pure CPU limit. This could mean something like the graphics driver running into a CPU limit rather than Xonotic itself. As suggested before, disabling compositing on Xonotic might be a good area to start if this is the case.

Rafallus is getting pretty middling performance there whereas you are getting something much worse. Disabling compositing for Xonotic may give a big speedup but I still don't think it'll close the gap.

When you say compositing do you mean aero? I disabled it and i don't get a better framerate.

Edit: got about 230 fps in omg and 110 with ultimate.
Phenom2 X4 925 2,8 Ghz, nvidia Gtx460

The FX is not a that good gaming prozessor compared to the latest intel, but it definitely IS faster than most cpus of a older generation! even in single threaded apps

I guess it's not the cpu!

Nyov got similar results as yours with a 6970gfxcard. And the 6000+ Cpu is as fast as my PII 925 in single threaded applications. (I know that because I upgraded form a 6000+)

It's a gfx driver issue i think.

Offtopic: The difference between 30-60fps is HUGE. You can absolutely perceive it.

More off-topic, I perceive a HUGE difference even between 60-120 fps. After getting used to playing on a 120Hz monitor, 60 fps almost feels like a slideshow, seriously! It's not placebo, I can tell in a second if my monitor is set to 120 Hz or 60 Hz just by moving the cursor around.

IIRC around 200 fps is where the human eye will stop noticing a difference if you ramp the framerate up further. (can't find source for that)

Darkplaces isn't multi-threaded? I thought it supported multi-core processors for years Of course it runs very well for me as is, but if this feature was added it might run even faster. So although I can't complain of its absence, I surely support the feature.

It *is* multithreaded, but not very much.
