While for the vast majority installing and running TOXIKK is a smooth process, there have been sporadic reports of the strangest problems that range from not being able to launch the game to server browser issues. The purpose of this guide is to give you a couple of tips for the most common fixes. This guide will be updated in the future.
INSTALL LATEST GPU DRIVERS
This may sound like an obvious thing, but it does indeed solve a lot of issues. Look in your GPU's control panel if it confirms that you're using the latest version and (if not) have them downloaded through that panel or check for the latest driver packages at your GPU manufacturer. Most common are nVidia and AMD:
Latest AMD/ATI Drivers for PC Windows Systems
Latest nVidia Drivers for PC Windows Systems
NOTE: For nVidia boards, you should also have the latest PhysX drivers installed.
INSTALL COMMON REDISTRIBUTABLES
These files should've been installed through STEAM with your initial game installation. However, if you encounter problems while running TOXIKK, we recommend to install them manually, just to make sure. You'll find them in:
..Steam -> SteamApps -> common -> TOXIKK -> _CommonRedist
You'll find three directories in this folder. Launch the following executables in each of these directories: DXSETUP.exe, dotNetFx40_Client_x86_x64.exe and vcredist_x86.exe.
INSTALL UNREAL ENGINE REDISTRIBUTABLES
These files should also be installed through STEAM with your initial game installation. But some version conflict or insufficient user rights might have prevented the installation. So, if you still encounter problems after applying tip 1 and 2, we recommend to install the UE3 redistributables manually. You'll find them in:
..Steam -> SteamApps -> common -> TOXIKK -> Binaries -> Redist -> UE3Redist.exe
Launch UE3Redist.exe and the redistributables should be installed automatically (NOTE: You may need to launch this file with admin rights on your Windows system).
USE MORE VIDEO MEMORY ON 32 BIT SYSTEMS
TOXIKK requires 4 GB of RAM (as per the minimum hardware requirements). If your Windows system is somehow restricted to administer less than this (although you have 4 GB installed), you may want to make more RAM available to your system by launching a command prompt and telling your windows to do so:
Hit the widows key and type:
- Code: Select all
Right click on CMD executable and choose 'Run as Administrator'
In the command prompt type in:
- Code: Select all
bcdedit /set increaseuserva 3072
Then restart your computer (this is important to apply the change) and launch the game again.
Hat tip to Butane for this.
MAKE SURE TO USE A HIGH PERFORMANCE GPU PROFILE
With some GPUs, TOXIKK sometimes is not recognized as an application that requires GPU acceleration. You may want to check if TOXIKK is listed among the apps that use a high performance profile. Also, if you're using a rare or exotic system (like maybe one of these dual GPU powered gaming notebook) you may want to make sure, TOXIKK is added to the applications that use your accelerated GPU (as opposed to your 2D integrated graphics). To achieve this, you need to open the control panel of your accelerated GPU and add TOXIKK manually (if it wasn't added automatically).
For AMD GPUs, make sure to add TOXIKK in your AMD Catalyst Control Center (if not already there). You can find a complete video explaining how to add a game to you Catalyst Control Center:

For nVidia GPUs, TOXIKK sometimes needs to be added to the nVidia Control Panel manually. This is escpecially true for M (mobility) GPUs. Here's a video that explains in detail how to add a game to the nVidia Control Panel and what tweaks can be done (the important part starts at 1:00 min):

PROGRAMS THAT MAY INTERFERE
If you're having trouble to have the servers displayed in the in-game server browser, please make sure that no third party programs interfere with TOXIKK or with STEAM. Since the authentication and the server browsing is mainly handled through STEAM, you may want to check this list of programs that cause possible issues. Disable the programs in questions and try connecting again.
EDIT INI FILES AT YOUR OWN RISK
While it might seem fascinating to individualize the game's INI files, you may encounter issues that may appear unrelated to the changed settings, but are in fact an aftermath of modified INI entries. If you still want to play around with them, here are a few things you should definitely avoid:
DO NOT change INI entries you don't recognize. When playing around with the INI files, you should be an advanced user who knows what he/she is doing. Otherwise you might just ruin your entire game experience and be required to re-install the game.
DO NOT set bAllowHighQualityMaterials to false, but leave it to bAllowHighQualityMaterials=true in UDKSystemSettings.ini. It might be tempting to set this to false to gain performance, but it will result in unpredictable glitches and you might even see visual obstructions that are in fact nonexistent (especially with terrain).
DO NOT set OneFrameThreadLag to false, but leave it to OneFrameThreadLag=true. Setting OneFrameThreadLag to false may result in performance drops of up to 50%, keeping your GPU from running at full capacity.
FIX OCCASIONAL CRASHES ON NVIDIA GPUS
Talking about INI editing: If you're using an nVidia GPU and encounter occasional crahes on your system, you may want to try to disable hardware support for PhysX (a hardware acceleration of physics effects that sometime may cause crashes due to nVidia incompatibilites on some of their GPUs). Open UDKEngine.ini. It's located at:
..Steam -> SteamApps -> common -> TOXIKK -> UDKGame -> Config -> UDKEngine.ini
Open it with your favorite text editior and find:
- Code: Select all
- Code: Select all
That should solve occasional crashes on some nVidia GPUs. Don't expect any changes in performance, as we're rarely using nVidia PhysX anyway (to maintain compatibility between AMD and nVidia GPUs).
