In-game gamepad button map settings.
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.
In the resources directory (in the game installation) create a file "config.ini" with the following content. 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.
config.ini
EnableColorCorrection=0
EnableCaustics=0
EnableShockwave=0
EnableLighting=0
EnableFilter=0
EnablePixelation=0
EnableBloom=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.
Another tweak mentioned by others: edit the MaxRenderScale value in options.ini (in your save data directory) to 1. This also gives quite a speed boost. 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.
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 )

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..."
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.
Some wireless keyboards might have the same problem, as there is a limit amount of combinations of keypresses these keyboards can transmit. You could alter the controls until this is not a problem anymore.
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
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 .
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.
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.
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.
