As a gaming keyboard, there are some ubiquitous features, including 1000hz polling, and full NKRO. The MasterKeys Pro L RGB retains the minimalistic, compact design seen previously with the Quick Fire XTi. It also features the complex driverless commands that make heavy use of Fn keys. To aid the advanced lighting effects and macros, ensuring fast, lag free operation, Cooler Master have equipped the MasterKeys Pro L RGB with an ARM Cortex M3 processor, that is said to be 25% faster than the Cortex-M0 processor that is commonly used in many other keyboards.
