Re: Gamers largely unaffected by KPTI?
Once the connection to the framebuffer has been established, I'm pretty certain that the game then just talks directly to the video card so likely no Kernel transitions needed at all after the initialisation. Possibly, if the game needs to tear down the connection and re-init the display (eg: if graphics mode has been reset, or if new shaders need to be compiled) .. but generally these chores are done during setup and then left alone during gameplay.
