"This update is notable for having a high number of improvements to game performance and compatibility. Please read the change notes.

Additionally, for x86_64 devices (most desktop computers), this update requires a CPU which has SSE4.2 instructions, and it is likely that all future releases will also have this requirement. This feature is available in all modern CPUs released in 2011 or later. The few users who have hardware which doesn't support this instruction set can compile the emulator from source with the ENABLE_SSE42 CMake option disabled."
