How do I fix input lag?

I get noticable mouse lag with lots of games, both old and new: nblood and glquake to name a few, quakespasm as well but to a much lesser extent, and more recent games like bioshock all have this. Whenever I move the mouse, ie. try to look around in game, the movement is delayed and sort of "smoothed out" as if the character was stoned or something. I haven't noticed keyboard lag, it may be there although less obvious.

What are the causes and possible solutions to this? The lag makes every game unenjoyable. I'm basically stuck playing gzdoom and winquake.

Alright,I'm playing Blood right now with BloodGDX.I'm on E1M3 and oh boy if this is hard.The enemies deal a shit ton of damage and I can barely find any ammo.
