Gaming at 120Hz?

[Dward]

Hi guys,

I had a problem trying to run my Samsung 2233RZ at 120Hz when I had my old GTX 460. It would flicker in windows, so I reduced the refresh rate back to 100Hz and all was good.

I recently bought a GTX 570, great card! I thought I should try 120Hz mode again so I did and to my delight, no flicker in windows use.

When I loaded up BC2 I got HUGE mouse lag and only around 30-40 frames. I was getting 80+ on my 460! So I did a quick google search and found that the high refresh rate might be the problem. So I reduced it to 100hz and loaded up BC2. No mouse lag and 120+ frames per second.

My issue is, if I want to try Nvidia 3D Vision in the future, which requires a monitor running in 120Hz mode, will I get this mouse lag again? My cable is definitely a duel link cable, it is the one that came with the monitor.

Is this a normal issue?

My computer is a i5 760 @ 3.8, 4GB DDR3 @ 1600Mhz, Windows 7

It sounds like some random config problem. Its not a normal issue. There should be no technical reason that raising the refresh rate lowers rendering speed.

Try reinstalling drivers and/or switching drivers.

Hmmm ok I loaded up BC2 (and MoH and ME2) using 120Hz. They all worked fine, no mouse lag! Strange

Maybe I did not have the correct refresh rate set up in-game in BC2 at the start. I changed the max pre-rendered frames from 3 to 2 also as over the years I have found that if any, 3 creates a little mouse lag, where as 2 has worked well for me over the years.

However I doubt with my new system setup there would be a difference between 2 and 3, correct? As back when my CPU & GPU were not so powerful that was when the pre-rendered frames actually made a difference

Thanks

NEW PROBLEM!:

At 120Hz, in Windows, my 570 stays at full speeds. 732/950. When I was running Windows at 100Hz it would down clock to 50/?? reducing the idle temperature.

The 570 idles at 45 now, instead of 35.

Is there a work around for this?

is that the only monitor you have hooked up to your pc?

??? I have a GTX 570 and it is always running at full speeds when I game... especially when playing Medal of Honor 2010 (PC)... I thought if your GPU is not running at or near full speeds then the bottleneck would be on your CPU?

read more carefully. he is talking about on the desktop not when he is gaming.

Found the issue after a fair bit of "googling":

Looks like I might try 110Hz in windows and 120Hz in gaming, should fix the problem
