PS/2 is an interrupt-driven interface. If the computer gets super busy, the USB device may not get its chance at the next polling interval, and why USB keyboards can lag in video games compared to PS/2 keyboards. Just because a product says "gamer" in its product name doesn't mean it really qualifies for that type of use. Did the keyboard come with a USB-to-PS/2 adapter? If so, the keyboard has the logic to switch between the different hardware protocols. If your computer has a PS/2 port then I'd use that for the keyboard. Gamers prefer PS/2 to USB because there is less delay or lag on keypresses with PS/2, and PS/2 supports more concurrent keypresses than USB. That's why some gamer mobos still come with a PS/2 port. Also, no reason to toss the availability of a USB port if a PS/2 port is available. I found: https://www.asus.com/us/Motherboards/CROSSHAIR_IV_FORMULA/specifications/ where it mentions one PS/2 port (for keyboard). If your USB gaming keyboard came with a PS/2 adapter then it supports both USB and PS/2 hardware protocols (internal logic has it switch between them). If the keyboard did not include a PS/2 adapter, it is a USB-only keyboard. You cannot simply plug a USB-only keyboard into a PS/2 adapter since the USB-only keyboard doesn't support the PS/2 hardware protocol. You can get an active hub that converts from USB to PS/2 to let you connect a USB-only keyboard to a PS/2 port, but those are more costly than just getting a USB+PS/2 or PS/2 keyboard. It has been a long time since I've seen this, but some old BIOSes must be configured in their settings to "Support legacy devices" which includes the PS/2 ports. If you see that setting in the BIOS then enable it should you decide to get a PS/2 keyboard or get a USB+PS/2 keyboard and use the USB-to-PS/2 adapter. Which USB "gamer" keyboard do you have?
