As odd as it sounds, try disconnecting any USB devices you aren't using. Some devices, like my speedpad, can cause excessive sampling, and that can be a considerable drain on the bus.

Try reducing your USB peripherals to your KB+M, and see how it works. Also try manually disabling various USB HID items in system settings.

Huh.. I'm using a xbox gamepad and my mobo has USB 3.0 that I plugged the pad in so I'll have to try it out and see.

TRY AT YOUR ON RISK!!! TRY AT YOUR ON RISK!!! TRY AT YOUR ON RISK!!!

For those who are not sure how to do this I recommend not even try it. But this is the location for the Virtual Memory. Instead letting your computer handle it, Custom Size your Virtual Memory so it will work a lot better.

1. Click Start or icon type System in the Start Search box, and then click System in the Programs list.
2. Click Advanced system settings.

If you are prompted for an administrator password or for a confirmation, type the password, or provide confirmation.

3. On the Advanced tab, click Settings under Performance.
4. On the Advanced tab, click Change under Virtual memory.
5. Click to clear the Automatically manage paging file size for all drives check box.
6. Under Drive [Volume Label], click the drive that contains the paging file that you want to change.
7. Click System managed size, and then click Set.
8. Click OK two times.
9. In the System Properties dialog box, click OK.
10. When you are prompted to restart the computer, click Restart Now.


To have Windows select the best paging file size, click System managed size. The recommended minimum size is the same as 1.5 times the RAM on your computer, and 3 times that figure for the maximum size. For example, if you have 256 MB of RAM, the minimum size is 384 MB, and the maximum size is 1152 MB.

For best performance, do not set the initial size to less than the minimum recommended size under Total paging file size for all drives. The recommended size is the same as 1.5 times the RAM on your computer. It is good practice to leave the paging file at its recommended size as performance can decrease if a paging file is too large. However, you may increase its size if you frequently use programs that use lots of memory, such as graphics programs or games.

------------------------------------------------------------

First, note that you should be concerned with *all* programs that start
automatically, not just with those that go into the system tray. Not all
autostarting programs manifest themselves by an icon in the tray.

On each program you don't want to start automatically, check its Options to
see if it has the choice not to start (make sure you actually choose the
option not to run it, not just a "don't show icon" option). Many can easily
and best be stopped that way. If that doesn't work, run MSCONFIG from the
Start | Run line, and on the Startup tab, uncheck the programs you don't
want to start automatically.

However, if I were you, I wouldn't do this just for the purpose of running
the minimum number of programs. Despite what many people tell you, you
should be concerned, not with how *many* of these programs you run, but
*which*. Some of them can hurt performance severely, but others have no
effect on performance.

Don't just stop programs from running willy-nilly. What you should do is
determine what each program is, what its value is to you, and what the cost
in performance is of its running all the time. You can try google searches
and ask about specifics here.

Once you have that information, you can make an intelligent informed
decision about what you want to keep and what you want to get rid of.

im also getting awful performance with this game. i have a radeon 6950 and the game constantly spikes. even when i try running the game at low resolution with all the settings turned down, the lag is still there

What is your computer spec's?

The USB theory makes sense. I have seven different things plug in USB wise.

Ya I agree about the USB theory, plus whats running in the background has well.

I tried switching around usb peripherals and it hasn't made any significant impact on my game play. I think it's because the game uses a lot of rendering options similar to those of crysis. However, that doesn't explain the low recommended and minimum requirements to run the game. So it could be just that that something else is the issue and I'm not getting what it is. It is possible that raising the page file could help. Generally the games I've seen that work on were games like Bloodlines where the file would get bigger and bigger through play session causing system lag over time. This is isn't the case here, the system lag begins outright but it's possible that my windows is set to auto-correct the page file size as needed. I'll got tweak with the settings of that and see what happens.
