I went through the tech support threads for the last year, and combined the solutions here. I’ve listed all the known solutions to crashing on load, major graphic issues, and multiplayer syncing - so look no further!
General Crashing (Launcher, Remastered, and Classics)
—>Verify game catch: Steam Libary->Right Click on the game->Properties->Local Files->Verify Integrity of game cache
—>Uninstall and re-install homeworld: Steam Libary->Right Click on the game->Properties->Local Files->Delete local game content, then install again.
—>Restart your PC after installing the game
—>Restart your steam client
—>Exclude the games in your anti-virus, and optionally temporarily disable anti-virus for testing.
—>Disable any overclocking software, especially GPU overclocking software.
—>Uninstall your graphic drivers, restart, then install the latest graphic drivers clean
—>Update your Microsoft .NET framework
—>Update your Microsoft Visual C++ Redistributables
—>Reinstall windows fresh, old drivers could be corrupted due to a bad shutdown, bad windows upgrade, etc.
—>Additional troubleshooting tips/details: https://gearboxsoftware.zendesk.com/hc/en-us/articles/205282200-General-PC-Troubleshooting-
—>If all else fails, you may have a hardware issue like a bad power supply.
When you start the Homeworld Remastered Collection, the Launcher opens first. If the launcher is crashing:
—>Try troubleshooting the launcher located here:
C:\Program Files (x86)\Steam\steamapps\common\Homeworld\HWLauncher\Launcher.exe
right click->run as administrator
right click->properties->and mess with compatibility settings.
—>If the launcher application wont start, you can create shortcuts to run the games directly:
- HW Remastered Multiplayer:“C:\Program Files (x86)\Steam\steamapps\common\Homeworld\HomeworldRM\Bin\Release\HomeworldRM.exe”
- HW 1 Remastered Campaign:“C:\Program Files (x86)\Steam\steamapps\common\Homeworld\HomeworldRM\Bin\Release\HomeworldRM.exe” -dlccampaign HW1Campaign.big -campaign HomeworldClassic -moviepath DataHW1Campaign
- HW 2 Remastered Campaign:“C:\Program Files (x86)\Steam\steamapps\common\Homeworld\HomeworldRM\Bin\Release\HomeworldRM.exe” -dlccampaign HW2Campaign.big -campaign Ascension -moviepath DataHW2Campaign
- HW 2 Classic: “C:\Program Files (x86)\Steam\steamapps\common\Homeworld\Homeworld2Classic\Bin\Release\homeworld2.exe”
- HW 1 Classic: “C:\Program Files (x86)\Steam\steamapps\common\Homeworld\Homeworld1Classic\exe\Homeworld.exe”
Homeworld Remastered Crashing
—>Basic debugging: Check the bottom of the log file for clues, by opening the following file in notepad:
“C:\Program Files (x86)\Steam\steamapps\common\Homeworld\HomeworldRM\Bin\Release\HwRM.log”
—>Advanced debugging: Go to your Steam Library and right click on Homeworld Remastered Collection. Click Properties, click Set Launch Options, and type in the following without the quotes “-luatrace”. Play the game until you crash. Go to “C:\Program Files (x86)\Steam\steamapps\common\Homeworld\HomeworldRM\Bin\Release\HwRM.log”. Review the bottom of log for any hints. Be sure to save a copy of the log, as its over-written the next time you start the game.
—>Player profile can get corrupted, delete it from: “C:\Program Files (x86)\Steam\steamapps\common\Homeworld\HomeworldRM\Bin\Profiles\Profile#”
—>Delete left-over files from old patches:
‘C:\Program Files (x86)\Steam\steamapps\common\Homeworld\HomeworldRM\DATAUPDATES’
This folder should only contain ‘DataMP.big’ (as of HWR v2.1)
—>Be sure to download the DLC campaigns
Homeworld 2 Classic Crashing
—>Add -nopbuffer to the command line arguments by going to Steam Library->Right Click on the game->Properties->Set Launch options. Or create a shortcut: “C:\Program Files (x86)\Steam\steamapps\common\Homeworld\Homeworld2Classic\Bin\Release\homeworld2.exe” -nopbuffer
—>Download an older version of atioglxx.dll and place the driver here: C:\Program Files (x86)\Steam\steamapps\common\Homeworld\Homeworld2Classic\Bin\Release
Easy download: http://www.moddb.com/games/homeworld-remastered/addons/homeworld-2-classic-crash-fix-atioglxx-fixzip
Complex download from AMD: Unable to run HW2 Disc(AND Gearbox’s classic) version on Win7 64bit AMD GFX [Workaround]
—>Player profile can get corrupted, delete it from:
“C:\Program Files (x86)\Steam\steamapps\common\Homeworld\Homeworld2Classic\Bin\Profiles\Profile#”
Graphic Issues (Remastered and Homeworld 2 Classic)
—>Disable any graphic overlay software: MSI afterburner, ATI afterburner, Raptr, Overwolf, AMD gaming evolved, etc. Even the Steam Overlay has been known to cause FPS problems as discovered here.
—>Change v-sync graphic options.
—>Set all graphic options to their lowest settings, and slowly turn things back on. Especially the texture size! (most people should use 1024 or 2048)
—>Try an older graphic driver that may be more stable. (Note: for Windows 7 64-bit with RX470: use AMD driver version 17, NOT earlier ones.) (Note: HWR runs OpenGL 3.3 not DirectX)
—>You can also mess with your ATI/Nvidia control panel application specific settings.
—>In the NVIDIA control panel, make sure the game is using the NVidia card, and not an integrated graphics card on the motherboard. Go to Manage 3D settings > Global Settings > Preferred Graphics Processor and select Nvidia processor.
—>Right click on the following file, click properties, and click compatibility. Disable display scaling for high DPI settings.
C:\Program Files (x86)\Steam\steamapps\common\Homeworld\HomeworldRM\Bin\Release\HomeworldRM.exe
–>For multi-monitor setups, press Ctrl+F11 to bind/unbind the mouse to HWR
Syncing or Bad Framerate in Skirmish/Multiplayer (Remastered)
—>Your FPS should never dip below 20fps or you risk syncing out of multiplayer games. HWR needs to run 20fps or more for MP, because that’s the rate used for the world-sim. (To enable FPS display, go to Steam Settings->In-Game->FPS counter). 3v3’s can make even the best PC’s cry. All CPU’s struggle when there’s a lot of ships in the game (HWR is still a single core game), and most video cards can’t handle HWR when textures from all 4 races are loaded.
—>If keeping your current hardware, you may need to set all the graphic options to the lowest settings and even lower your resolution to 1024x768.
—>Upgrade your PC. This is a single core game, so you want a great cpu for single threaded applications. This list ranks them: https://www.cpubenchmark.net/singleThread.html Graphics cards aren’t as important if you set all your graphics low, but if you want to set them high you’ll need a good card with 4GB of memory to handle textures from all 4 races. Also the game only uses 2GB of RAM, so that’s not very important. This is the setup I run, and big 3v3 battles can still take it down to 25fps at 1080p with all graphic options near their lowest settings: i5-4690 3.5 ghz quad core, 8 GB RAM, Radeon R9 380.
–>If your unable to build ships on a certain row of the build menu, just restart the game or Alt-Tab. Sometimes the mouse doesn’t register on the menu.
