V-Sync caps my FPS at 60 when I have a 120Hz monitor and GTX 690

Hi

I have a Samsung SA700 120Hz monitor however, when I play any game (such as Battlefield 3), V- Sync seems to cap my FPS at 60 instead of 120. Can anyone tell me why this is happening? Even when I select Adaptive V- Sync, my FPS is still capped at 60. However, when V-Sync is disabled, my FPS jumps back up to over 120, which is causing tears in game play.

My specs are:

CPU: i7- 3770K
GPU: GTX 690
Motherboard: Asus Sabertooth Z77
Power Supply: 1350 Watts
RAM: 16GB

I would have to assume that's a driver limitation, intentional or not. My only real recommendation is to email nVidia about this, but I doubt they would be very sympathetic. 60Hz constant is quite a treat, and any more would make negligible difference to your eyes.

Then again, you spent a fortune, so they really should be kissing your ass anyway. I'm interested to know how they'd respond, so keep me informed.

Is this just on Battlefield 3 or all games? Also it could be that Battlefield 3 has a 60fps cap with V-Sync enabled. But as RS1no2047 said 60fps is completely playable in every way.

It could be a limitation of your video cable if you aren't using dual link dvi cable, you need one to do 1080p 120hz.

Thanks for the reply. I just emailed Nvidia so yeah, I'll let you know what they say

Hi bryonhowley, yeah it seems to be for all games I have, such as Mafia 2, Just Cause 2, Batman Arkham City... I'm really confused as to why this is happening though and since I'm capped at 60 FPS, any sudden drop is very noticeable

Hi kevin83, I just re-checked and yep, I am using a dual link dvi cable

Maybe check your cable like kevin83 said. Make sure it is a DVI-D or DVI-I dual-link cable.

Erm, yeah its definitely the DVI-I dual link cable that its connected to
