Bioshock V-Sync Probs

[Born_2_Kill_83]

Pleased to say everything runs great on my rig other than one problem.
Flashing/Strobe effects in game courses blocky/line break ups in the graphics with V-Sync disable. Enable this setting and everything is fine though it does hammer my frame rate quite a lot.
Any surgestions? By what percent running V-Sync will my frame rates drop?
What are you guys running? On or off?

i ran it off sitting between 40 and 60 fps the hole time apart from the end were it hit 30 once for such short a time its not a worry.
i got the problem once that you are refering to in the ball like sub at the start when the lights flashed apart from that never noticed it any were else.
what drivers are u using i had the beta 163 drivers from nvidia

Yes 163 just downloaded last night (bioshock ones)
With V-Sync on I get between 30/60FPS mainly running at 60FPS the whole time but at the beginning it gets stuck @30 till you come out of the bubble. I can still feel the slow down though with V-Sync enabled.
I have just brought a new monitor is that partly to blame? its a Samsung SyncMaster 205BW. Dont the word "Syncmaster" mean anything lol

Is it safe to say its down to the monitor/TFT?

Can I run highter than 60 on a LCD, if so would this solve the problem?
