Vsync off

[Haste]

Of course you can play at 60

I thought this was true back when I was playing the game on my old system.

Nowadays if I try to play at 60 FPS I'm stuck in ships the size of Gunboats and up. The mouse lag is so severe aiming fighter guns precisely is entirely impossible.

It's an issue I only have with Freelancer, and didn't have in the past. I can understand why you (if you don't have such mouse lag issues) feel that 60 is perfectly viable - after all, in your own personal case that's perfectly true. However, for some of us the game is simply unplayable at the 60 fps vsync cap.

Plus, there's no actual difference on other players' screens between an enemy player playing at 30, 60 or 120 FPS. Things only get iffy once you approach the 160 region. Of course, players will still accuse others of jittering when they lose a PvP fight, because how else is their ego going to handle the blow?

... OP asked for a way to disable Vsync to achieve high framerate to reduce input lag. The downside is the risk of jitter on another player's screen ...

There is no risk of jitter as long as you stick to a healthy cap of 120. The margin between 120 and 180 (180 is the point at which you irrefutably jitter) is large enough that any inaccuracy in your capping software won't cause you to jitter periodically. Anyone who claims to be capped at 120 and still jitters either is a liar, or is like me and has accidentally undocked in Conn without turning on dxtory. It's rather blatant in that case however as I'd be spiking all over the place at that lovely 180 FPS. Oh, the other possibility is that you're mistaking lag for jitter. They're not the same thing. In fact, a rather well-known PvPer recently made that mistake, accusing me of jitter while he was personally hopping about on the screen varying between 10 and 20% lag.
