i5-2400 CPU
GTX 460 GPU overclocked to the following specs
[image loading]

Problem exists without overclocking and on all graphics settings.

Basically, I'm getting drops to 0fps and chugging while using 2 monitors. One is 24 inch, one is 21.5 inch, 1080 resolution, both 60hz.

Aero is disabled.

Nvidia drivers were clean installed to most recent. Problem existed with older drivers.

Anybody have any advice?

Are you gaming across both of them?

No. Only running SC2 on one. Problem exists in full screen and windowed mode, and regardless of what I am using my other monitor for (including if it's off) and regardless of which screen I use for the gaming.

I have 8gb of RAM and am running windows 7 64 bit. Neither my RAM nor my CPU max out.

I've had this issue since I started using a multi-monitor setup 2.5 years ago. It's really irritating. Even after switching out my CPU and motherboard this year it still happens. I'm convinced it is an SC2 issue at this point because I've had it happen on an AMD CPU, dual-GPU setups, single GPU setups, on Intel CPUs, and even on my Mac when I have it running two monitors.

It happens inconsistently, and usually is just a weird hang or FPS spike for like 2 seconds then the game runs fine. But non-the-less it is quite irritating.

Okay, seriously? Nobody has any idea or suggestions?

How old were the old driver versions you tried? The last few months all versions were a little or completely broken for me. 314.22 was working fine. The newest 331.40 seems to work well.

Maybe try to see what's up if you use the motherboard+CPU integrated graphics for the second monitor?

You have to explicitly enable integrated graphics in the BIOS. By default, it's usually automatically turned off when a graphics card is installed. After it's enabled in the BIOS, it will show up in the Windows device manager. You might have to wait a little for Windows Update to get drivers for the device before it will be named "Intel HD Graphics" instead of "standard vga".

If you connect a screen to the motherboard, everything drawn on it will run on the integrated graphics, so you can't use your graphics card for 3D on that Windows desktop (I think), but normal desktop stuff should work well.

I've gone all the way back to 2011.

Unfortunately, I can't just use integrated graphics for the second monitor. I need my card for work.

Some of these might sound weird, but they are all things that helped with slight stutter or suspicious mouse pointer latency at some point, and maybe your 1-2 sec freezes are related.

Try this in the BIOS:

See if a newer BIOS version fixes things.

If your board's BIOS settings allow access to your BCLK ("base clock"), see if your board runs at 100.00 MHz or something a little off. It might be a little higher than 100 to cheat in benchmarks, and it might fluctuate. You will want it as close to 100 as possible. You might have to try a setting like 100.01 as 100.00 might be interpreted the same as the default "Auto".

If you have a "spread spectrum" setting, try with it disabled.

Manually set the pci-e graphics card slot ("PEG") to Gen2 instead of Auto.

Try to disable all CPU power saving features as an experiment. These are C1E ("Enhanced Halt"), C3/C6 ("C-States"), EIST ("Enhanced Intel Speed Step").

Look for HPET ("high precision event timer") in the BIOS and try to see what happens if you flip that setting to the opposite of what it's now.

In Windows, look for this:

Make sure Java runtime environment stuff is not running if you don't need it.

Uninstall weird programs that came with your LAN or WLAN adapter.

You might want to experiment with the settings in the Windows power options plan you are currently using. There's also a "power management mode" option in the NVIDIA control panel.
