XSplit Broadcaster and XSplit Gamecaster support both 32-bit and 64-bit operating systems. We highly recommend running our applications on a 64-bit operating system to ensure optimal performance.
When using a 32-bit operating system, the XSplit applications will attempt to utilize a special mode to be able to use more memory. However, this mode is not normally available in 32-bit operating systems which may lead to performance issues with XSplit, especially with more complex and content-heavy presentations.
If you are running a 32-bit operating system but your CPU supports 64-bit instructions, it would be ideal to upgrade to a 64-bit operating system as this will allow you fully maximize the capabilities of your hardware.
