If course, all that goodness would be for nothing if we don't bake a proper version of the game. It's been a while but I think Quake server tickrate is likely to be on the low side.
Quick searching confirms that. From https://speeddemosarchive.com/quake/qdq/articles/WallHug/fra...
"In normal Quake, the server framerate is controlled by a console variable called sys_ticrate. This measures the amount of time each frame should last, and its default value is 0.05 (that is, twenty frames per second.) Most server administrators don't bother to change this."
I say someone should take your idea, fix Quake 3 to run at 1khz on both the client and the server, then bake that into fpga. I would buy it
