Upcoming Forum Overhaul

We are starting the work to switch our forums, which have been based on a version of the Vbulletin forum software since their inception with the Red Orchestra mod (then VB 3 and currently VB 5.1) to an all new forum software called Xenforo. After researching it, we feel Xenforo is a better choice for the future as it has a vibrant modding and addon community that will allow us to extend the functions of these forums in ways players will enjoy.

As part of this, at some point in the near future these forums will be locked down so we cant merge over all of the existing content into the new forum database. It will likely then be a few more days as we work on the new forum and correct any issues from the merge.

Please use common courtesy, and enjoy using Red Orchestra's forums
[COLOR=darkred]Offensive material
The following is a list of some things that MAY be considered "offensive" by the moderators and the team. This is NOT an exclusive list and it does depend very much on context.

Crossing the line into "offensive" territory is likely to get you asked to change your name, sig or avatar or to withdraw/delete posts. This will be done politely by the moderators. If you refuse to comply further action WILL be taken once started, ultimately leading to banning from the forums.

A key point: please attempt to use your brains. What is mild humour to you may well be deeply offensive to others. While we have no intention of acting as politically-correct "thought police", we are on the lookout for those things that can cause offense and, in some cases, are actually still illegal in some jurisdictions.
  1. Names recalling notorious war criminals or personalities.
  2. Names recalling atrocities and war crimes in general, or units with particularly odious histories.
  3. Use of obscenities and expletives.
  4. Blatant racism, mysogynism or many other "ism"s.
  5. Use of symbolism and regalia recalling Nazism or Fascism; this does not include pics of soldiers who happen to have such symbols on their uniform, unless we feel this has been done to provoke. Please note that many Nazi symbols (including the Swastika) are still illegal in Germany and other countries and considered deeply offensive by many Europeans.
  6. Use of symbolism and regalia recalling Stalinism.
  7. On both the previous two, the moderators' views on the intention and impact of use of such symbols will be final - not yours. Please be understanding if you are advised to change something.
  8. In general, if a sig/avatar represents your allegiances in-game and is clearly "in part", it is likely to be fine; if the moderators feel you are trying to demonstrate unpalatable political allegiances, or to use it in an attempt to ridicule or provoke others you WILL be asked to change it. RO is NOT the place to make any extremist political statements of any kind.

So people get the idea, some examples that would be considered offensive, numbered as above:
  1. "Hitler", "Beria"
  2. "NKVD Blocking Detachment", "Einsatzgruppen"
  3. This one should be pretty obvious...
  4. So should this - and it includes calling all Germans "Nazis" and all Soviets/Russians "Commies". It got boring 50 years ago, so stop it.
  5. Use of swastikas, fasces, SS-runes and so on for the Axis.
  6. There is actually very little overt symbolism from the Stalinist era; the hammer-and-sickle isn't offensive per se.

A simple rule-of-thumb: many Europeans find Nazi symbolism of any sort offensive; many Americans still find Soviet symbolism offensive. Engage your brain before using.

Final Note: this is NOT open to debate, so please do NOT start whining and moaning if a moderator asks you to change something. They will advise at first, giving reasons, then, if you take no notice, they will step up the pressure through to banning.

    Changing Map Loading Times (Online Gaming) & Note about General Performance during the Game

    I have to Say that before i changed anything with PreCaches, CacheSizeMegs, and "Reduce Mouse Lag", also Defragment my Drive (Hard Disk), i had to wait like 2 minutes in average.
    So thanks for this thread and all its support by any posts.

    I decided to test the configuration with Precaching in the Option 2 given by “Zetsumei”, as “Them” said to test different settings. So remember this is with my own computer, which in this case is a laptop. So the configuration might be different for others.
    My System Details:
    OS: Windows Vista 32bits
    Processor: Intel Pentium Dual CPU T3200 2 GHz
    RAM: 3 GB
    Graphics Card: NVIDIA GeForce 9200 GE
    Sound Card: Conexant High Definition SmartAudio 221

    (Does 400MHz in the processor make a difference, for the recommended specs?)

    Anyway, I decided trying to help with some tests, as also, seeing what is the best configuration for me. I hope this info will be helpful for anyone having the same issues with loading maps, and it’s bothered/annoyed since they even have the recommended System Specifications.
    Lastly I hope that this will help Tripwire to figure out what it causes, and what can be changed, so we won’t have these troubles with manually configuring.

    Before I done this PreCache, CacheSizeMegs, "Reduce Mouse Lag", and Deframentation changes i had my Game Details at Low running in 800x600 windowed mode (remember that I had 2 minutes in average to load), and this tests were made after the Deframentation with: Game Details at High in 800x600 windowed mode.

    -The experiences consists in changing the Precache settings as for each experience is told, with 6 times counting (in seconds) changing map in online servers, ALWAYS lower than 80 ping (the best i can get is a 30/40 ping server). With only me in the game (blowing myself or letting get eaten by the monsters) so it would be much faster.
    Note: I close the game every time and then change the Precache settings before the next experience.

      Reporting Back (2)

      Experience 1 ("Default")

      Game Details=High
      Windowed mode
      With Defragmentation done
      Reduce Mouse Lag = On
      All Precache Settings=True (Except bNeverPrecache=false)

      In Seconds
      3-18,3 (freeze by 1 second)
      5-26,4 (freeze by 3 seconds)

      General Performance in-game Note:
      No in-game lag spikes. No Crashing. Freezing at 3 and 5 attempt. Runs good.

      By this one I would conclude now that the defragmentation did a lot of difference in the loading. It’s quiet normal that this would happen tough.
      (Imagining a room and the stuff inside it, if you have your room cleaned and organized, you’ll find the stuff you need more quicker then with it as my room usually looks like: a mess! Lol. Same as the Hard Disk would be the room, the stuff would be the KF files, and you the processor.)

      The files from time to time get “lost” in the drive, and so, when the processor tries to read the files it needs, it takes more time then if the files are all in their places.

      The rest of the experiences were with:
      Game Details=High
      Windowed mode
      With Defragmentation done
      Reduce Mouse Lagging = Off

      Experience 2
      -"UsePrecaching=True" to False, the "bNeverPrecache=false" to true and "UsePreCache=True" to False.
      As the Option 2 says.

      1 - 18,7
      2 - 11,2
      3 - 8,5
      4 - 12,0
      5 - 10,9
      6 - 9,7

      General Performance in-game Note:
      Some lag spikes during the game. No crashing or freezing. Runs ok.

      Experience 3
      -"bNeverPrecache=false" to true and "UsePreCache=True" to False.
      Leaving the "UsePrecaching=True".


      General Performance in-game Note:
      No in-game lag spikes. No crashing or freezing. Runs great.

      Experience 4
      -"UsePrecaching=True" to False and "UsePreCache=True" to False.
      Leaving the "bNeverPrecache=false".


      General Performance in-game Note:
      In-game lag spikes, during the game. No Crashing. No Freezing. Runs ok.

      Experience 5
      -"UsePrecaching=True" to False and "bNeverPrecache=false" to true.
      Leaving the "UsePreCache=True".


      General Performance in-game Note:
      No in-game spike lags. No crashing. No freezing. Runs good.

      Experience 6
      -"bNeverPrecache=false" to true.
      Leaving the "UsePrecaching=True" and "UsePreCache=True".


      General Performance in-game Note:
      No in-game lag spikes. No crashing. Freezing a bit in the 3 attempt. Runs good.

      Experience 7
      -"UsePrecaching=True" to False.
      Leaving the "UsePreCache=True" and "bNeverPrecache=false".

      5-25,0 (Not Responding for about 5 seconds)

      General Performance in-game Note:
      Lag spikes at the beginning and during the game. No crashing. Freezing at the 5 attempt and 2 times during the game. Runs ok.

      Experience 8
      -"UsePreCache=True" to False.
      Leaving the "bNeverPrecache=false" and "UsePrecaching=True".

      4-39,9 (weird..)
      Extended this one because of that 39,9 witch was weird since the 7 and 8 were a 8 and a 10.

      General Performance in-game Note:
      No in-game lag spikes. No crashing. Freezing a bit in the 4, and 5 attempts. Runs ok, but i think not 100% smooth.


      Best Average Time Loading: Experience 5
      Best In-Game evaluation: Experience 3

      Best 3 Average Time Loading (Best to Worse): 5, 4, 2.
      Best 3 In-Game Evaluation (Best to Worse): 3, 5, 6.

      I guess I will use the settings for the fifth or third experiences. Even though the loading time wasn’t so good in the third experiment (21,4), I had a great in-game experience. Still, the best in general performance was the Fifth Experiment.

      So it’s done.
      Now I would be appreciated to know, opinions, ideas, self-experiences.
      Was this worth for anything?
      Were the conditions good enough?
      What suits best for you? Telling what Specs you have. (in a quick view without all the details)
      Am I wrong in something I said?

      Thanks for your time reading this huge post.
      Hope it helps somehow…

          A thread that might help too:

            Hm here's a problem.

            Option2: Turn of PreCaching
            1) Find your KillingFloor.ini file located in the steam/steamapps/common/KillingFLoor/system folder (hint it looks like a notpad icon with a cog)
            2) Change the values listed below:

            under [ALAudio.ALAudioSubsystem]
            Change UsePrecache=True to UsePrecache=False

            and under [Engine.LevelInfo]
            Change bNeverPrecache=false to bNeverPrecache=true

            and under [Engine.NullRenderDevice]
            Change UsePrecaching=True to UsePrecaching=False

            and under [D3DDrv.D3DRenderDevice]
            Change UsePrecaching=True to UsePrecaching=False

            and under [D3D9Drv.D3D9RenderDevice]
            Change UsePrecaching=True to UsePrecaching=False

            and under [OpenGLDrv.OpenGLRenderDevice]
            Change UsePrecaching=True to UsePrecaching=False

            and under [PixoDrv.PixoRenderDevice]
            Change UsePrecaching=True to UsePrecaching=False
            This entries don't exist in my .ini file!
            (ALAudio exists)
            May someone upload his .ini file using a win7 64 bit system?

              Options 2 and 3 helped me and four other friends go from 5 minute load times to instant. Thanks!

                You are probably looking at the user.ini and not the killingfloor.ini

                  Can I ask that this thread be retitled to make it clearer that its content addresses both long load times and ingame temporary freezes?

                  - setting "DetectedVideoMemory" higher (or at least having it reflect actual video memory)
                  - setting "NVidiaPreFX" to True
                  - setting "CheckForOverflow" to True

                  Still got them but they're not quite as bad.

It also means that you must have a properly defragmented harddisc or otherwise you could get big freezes once the first specimen dies or spawns for example, as that would be the moment when they would be loaded.
                    Am I right in saying that turning off precaching would only give, potentially, better performance if your PC has a low amount of RAM installed? Wouldn't it actually cause worse performance on a system with a large amount of RAM installed? (4GB+).

                    Why would it ever result in a higher performance on a high-end-ish system?
