Run the game, then go to the task manager. Right click on the process, something like quakespasm.exe or whatever the process is called. Go to set affinity and uncheck all but one core.

Well, most processors these days have multiple cores. The cores is the actual number of CPUs used for running the game. The more cores, the more power your computer will have to run the game. Of course, it seems to give the game too much power, making it accelerated to the point where everything is fast as you described.

I have no idea why you are having to limit your cores as I can run my game fine on a quad-core processor. Still, it is worth a try and might be the solution to your problem of fast moving stuff in Quake.
