If this game is like all other then the game runs at your desktop refresh rate, I run a refresh rate of 100--if game refreshes screen that fast it can lower FPS...There is a console command which I added to my .cfg (I have my own set of configs and aliases) if you dont, put it in----- mainconfigsunnamedsoldier.cfg

the command is: seta r_displayrefresh 85

should set in-game refresh rate at 85Hz

Well, i'm not really positive, but it works in Half-life and it is a console command in MOH-AA--If i'm making an ass out of myself please dont flame me , just tryin to help ppl like me that just barely meet system requirements (which I think is WAY to low)

Section 1 - The Basics

In the first part of this series, we took a look at What does 'Optimal' Refresh Rate really mean? While that discussion focused on the 2D side of things, refresh rate also plays an important part in the 3D world...in the form of VSYNC. But what is VSYNC?

Well before we can answer that, a little discussion of how 3D works is required. In order to get a smoother transition between frames in 3D games, the video card puts the contents of the upcoming frame into its frame buffer. [The frame buffer is part of the local memory that resides on the video card itself] It then moves the contents of the frame buffer to the screen. When this is complete, the frame buffer gets the next frame. This process repeats its self over and over.

Now, what is VSYNC? Well, VSYNC is basically the synchronizing of buffer swaps with your monitor's refresh rate. With VSYNC enabled, frame rates will not exceed the monitor's current refresh rate for that particular resolution. For example, if your monitor is using a refresh rate of 85Hz at 800x600, with VSYNC enabled, you will theoretically never exceed 85fps. So the refresh rate creates an artificial barrier that limits the frame rate.

So what happens if you are playing on an older monitor that only supports a 60Hz refresh rate. Will you have to live with a maximum of 60fps (assuming that your system can generate more fps)? Not necessarily. Newer video cards give you the option of disabling VSYNC. What happens is that this allows the buffer swapping to occur without synchronizing with the monitor's refresh rate. If it really was the refresh rate limiting you, disabling VSYNC may allow you to obtain frame rates in excess of 60fps. This, unfortunately, can also cause what are called 'visual anomalies': image tearing and flashing polygons. Some games run fine with VSYNC enabled, while other games crumble when VSYNC is disabled.

If you look in Display Properties, you may see an option to disable VSYNC in OpenGL by not Direct3D. Why is this? Well, in order to receive Microsoft's WHQL certification, this option cannot be available. Microsoft does not want Direct3D games to be played without VSYNC.

Running the game @ the refresh rate of your monitor means you have enabled the Vsync. The Vsync sets a fixed refresh rate in the game to match the refresh rate of your screen. Disabeling this has an advantage as you won't be limited in termes of frame rate

It should run at the refresh rate of the resolution your running the game in. If you set it too 85 and have vsync on you will only get a max of 85 fps. If your running at a refresh of 100 and try setting your maxfps to 100 "com_maxfps", the default for the game is 85.

How do you turn off vsync?

I know in all my other games, vsync kills my framerates.
