Known Issues
Hey everyone!
Thanks for being patient with us so far.
Here is a list of issues we already know about. If possible, we will provide instructions on how to fix them on your end.

If you encounter a bug not in this list, make sure to send a detailed bug description to isaac@nicalis.com, along with any log files, crash dumps, screen shots, saved games you think might help us.
Locate the save data directory in the following location, depending on your operating system:
  • Windows Vista/7/8: Inside your user folder, usually C:\Users\<username>\My Documents\My Games\Binding of Isaac Rebirth
  • Windows XP: Inside your user folder, usually C:\Documents and Settings\<username>\My Documents\My Games\Binding of Isaac Rebirth
  • Mac OS X: ~/Library/Application Support/Binding of Isaac Rebirth/
  • Linux: ~/.local/share/binding of isaac rebirth
Locate your Steam Cloud remote directory in the following location, depending on your operating system. This is where your saved games are located:
  • Windows: Inside your Steam install folder, usually C:\Program Files (x86)\Steam\userdata\[account id]\250900\remote
  • Mac OS X: ~/Library/Application Support/Steam/userdata/[account id]/250900/remote
  • Linux: ~/.steam/steam/userdata/[account id]/250900/remote

Afterbirth crashes/glitches on startup, Rebirth ran fine
This might be caused by leftover Rebirth mods. After installing Afterbirth, make sure to get rid of all Rebirth mods.
Right click on the game in your Steam client, go to "Properties", "Local Files", "Browse Local Files..."
Enter the "resources" folder. There should be one folder in there called "packed". Anything else in the "resources" folder (xml files, gfx folder, etc) you should probably delete if you have issues with running Afterbirth.

Crash on game initialization
Some people are not able to start the game right now. Usually the "Preparing to start game window" pops up and nothing happens. The log looks like this:
timeBeginPeriod( 1 ) GLFW Error 65542: WGL: The driver does not appear to support OpenGL GLFW Error 65542: WGL: The driver does not appear to support OpenGL Failed to create OpenGL window / context Caught exception, writing minidump...
Most likely some OpenGL extensions are not supported by your graphics card or driver. There is nothing we can do about that at the time being.
  • Try installing the most recent graphics drivers. Sometimes it helps to uninstall the drivers included with the operating system and installing the ones directly from the vendor site (NVIDIA, AMD, Intel ...).
  • If you have both an integrated on-board graphics chip, and a discrete graphics card, make sure running the game on the discrete graphics card.
Important! Binding of Isaac: Rebirth needs OpenGL 2.0 support, OpenGL 3.0 is recommended. If your graphics card does not support OpenGL 2.0, you are probably out of luck.

Another common reason for the game to crash at startup is that the game files are broken. You can tell the Steam client to automatically check the game files for errors and re-download broken ones. Right click on "The Binding of Isaac: Rebirth" in your games list, select "Properties", "Local Files", "Verify Integrity Of Game Cache..."

Keyboard getting stuck randomly
This seems to mostly happen on the Logitech G110 keyboard, but others might be affected, too. Try to disable controller hotplugging.
You can disable gamepad hotplugging by changing "ControllerHotplug=1" to "ControllerHotplug=0" in the Options.ini file, which is located in your save data folder. Look at the top of this page for instructions on how to locate the save data folder on your PC.

Sound effects not working
A common issue seems to be that the music is working, but the sound effects are either missing or only coming from one side of your Stereo speakers.
You can try different settings for your speakers, e.g. switch from Surround to Stereo mode or vice versa.
What could also work is using a different version of the OpenAL libraries.
  • Install the OpenAL libraries from https://www.openal.org/downloads/oalinst.zip
  • Go to your game folder by right-clicking on "The Binding of Isaac: Rebirth", then selecting "Properties", "Local Files", "Browse Local Files..."
  • Delete or rename OpenAL32.dll
If the instructions above solve your sound effects problem, we would appreciate a short mail to isaac@nicalis.com.


Speed issues, unstable framerate
For some players the game is running either too fast or too slow, on systems where performance is not the issue. If you are experiencing this, try disabling VSync by changing "VSync=1" to "VSync=0" in the Options.ini file, which is located in your save data folder. Look at the top of this page for instructions on how to locate the save data folder on your PC.

Performance issues, or shader problems
In case you are suffering from speed issues because of slow graphics hardware, or if some shaders don't work for you, you can disable certain effects.
Locate the resources folder by right clicking on the game in your Steam client, then selecting Properties, Local Files, Browse Local Files. Double click on the resources folder.
On Mac you have to right-click on the app bundle, select "View Package Contents", go into Contents/Resources/resources, then create the file there.
Create a new file called "config.ini" with the following content.
[Options] EnableColorCorrection=0 EnableCaustics=0 EnableShockwave=0 EnableLighting=0 EnableFilter=0 EnablePixelation=0 EnableBloom=0 EnableWaterSurface=0 EnableInterpolation=0
This will disable most special effects. If you only want to disable certain effects, you can do so by replacing 0 by 1 for some options. I would recommend leaving the EnableLighting option on because it adds a lot to the game's atmosphere.

For some weak graphics cards, the fill rate might be a problem. Open the options.ini file in your save data folder with a text editor. Look at the top of this page for instructions on how to locate the save data folder on your PC. Look for a line saying "MaxRenderScale=2" and change that to "MaxRenderScale=1".
This will make the scrolling more choppy and add some artifacts to scaled sprites, so you might want to change it back in case your experience isn't improved by it.

Audio noise for hardware connected on USB
If you experience crackling, or otherwise scrambled audio, and your audio hardware is connected via USB, it might be that the gamepad hotplugging is interfering with your USB.
You can disable gamepad hotplugging by changing "ControllerHotplug=1" to "ControllerHotplug=0" in the Options.ini file, which is located in your save data folder. Look at the top of this page for instructions on how to locate the save data folder on your PC.
What also might help is to avoid connecting your audio hardware (speakers, headphones, headset, microphone) via USB, if that is an option for you.

Motion sickness caused by the camera
You can switch to a different camera mode by changing "CameraStyle=1" to "CameraStyle=2" in the Options.ini file, which is located in your save data folder. Look at the top of this page for instructions on how to locate the save data folder on your PC.

Thanks for the update that you guys are looking into the issues!

I thank you for giving us a heads up on what is going on. I know there is a lot of people who are upset right now. I hope this communication can help settle some of these concerns.

I am not sure if this is a bug, but back when wotl got released you would get a crazy amount of rare/good items. this is happening to me as well. i have done 8 runs and have encoutered:
-Prayer card x3
-The one hit shield per room x3
-controllable tears x2
These are just a few examples.
Again, not sure if i got insanely lucky or if this is actually bugged

I have a problem when I click on play steam says its launching but just keeps clicking out, so frustrated
Hunter Nov 5, 2014 @ 12:57pm 
I've looked around alittle and didn't see this, so I was wondering: Is there a fix for there being no sound effects in the game? The music and everything else plays fine but even when I have SFX at max it doesn't work.
Karam Nov 5, 2014 @ 1:02pm 
Can't start the game. It stops working when i start. My video card's driver is up to date
SpoonyBob Nov 5, 2014 @ 1:04pm 
Also noteworthy may be keyboard issues several of us have had (Logitech G11 and G110 that I know of).

It is similarly fixed by changing "ControllerHotplug=1" to "ControllerHotplug=0" in the Options.ini file.

Hi, I've also found a kind of bug/exploit. If you have Ankh and you die , you're revived as ???. But, if you die as ??? and hit restart, it spawns you back as ???. I have not beat the game even once, so I found this interesting.

There's a lot of threads going around about the game not saving data at all and causing people to lose progress, which might be worth adding to this list. There's been some talk that it may be related to access priviledges (the game's being barred by the system from modifying save files), OR that it's tied to the game trying to save to the wrong location entirely, but idek.

I have an issue, although I don't think it's a bug. Whenever I start up BOI: Rebirth and start a run, my game will freeze after five or so minutes of play. I will then get an error message stating "Application has been blocked from accessing Graphics hardware." and the game will stop working and must be closed. I then have to restart my computer. My graphics card is an NVIDIA GeForce GT 745M btw.

Is this a bug or some other issue?
