Does using MSKLC create noticeable lag with gaming?

I'm looking for a keyboard layout program, and want to stick to reputable tools, preferably Microsoft tools. Does Microsoft Keyboard Layout Creator (MSKLC) cause any noticeable lag with gaming? I have a Logitech G610 keyboard, which isn't programmable with Logitech software.

I original was going to use Powertoys' keyboard manager, but Microsoft says, "We suggest that you avoid using Keyboard Manager when playing games as it may affect the game's performance. It will also depend on how the game accesses your keys. Certain keyboard APIs do not work with Keyboard Manager."

Thank you.
