Solved ModernWarfare 2 suddenly running sluggish

Specs: Windows 7 Professional 64-bit, Core i5 3.2GHz/4GB PC3-12800
Hello. Last week I built a new computer, my first in about 3 years, with the primary purpose of playing newer games, which I have not been able to do with my old system since it pretty much tanked on everything released from 2004 onward. My new computer specs are as follows:

EVGA P55 SLI Motherboard
Intel Core i5 3.2GHz 655K Unlocked
4GB OCZ Reaper PC3-12800
1TB Seagate 7200 + 250GB Western Digital 7200
XFX nVidia GTS 250 512MB
22' Samsung Syncmaster 204BW
Rosewill Xtreme 850W PSU
Raidmax Iceberg ATX Case

The only noticeable issue I have had with the machine thus far is the onboard sound with the motherboard. It has a tendency to cut out after about 40 minutes or so of Modern Warfare 2, but this does NOT happen during TF2, Half Life 2 DM or Amnesia The Dark Descent, which I played for much longer periods of time. The sound goes out entirely, no system sound, no music, absolutely nothing. A restart remedies the problem. However, it now seems that my onboard sound is dead entirely as it no longer works at all, even at start-up. I installed my Audigy 4 soundcard from my previous build about 20 minutes ago and I now have sound again.

Now I told you that story to tell you this one. Yesterday afternoon (Oct 20), MW2 ran beautifully. It was such a blast. I left and went to class. I got home around 7:30, and booted up MW2 again to get a few frags before homework. However, I noticed a colossal drop in video performance this time. The game now graphically tanks during sequences of open area stretching across the map, a problem I did not experience just hours before. I also notice a funny crackling static sound when I face open areas in game, but when I look at a corner or something close quarters, the sound is normal and the frame rate is normal. This renders the game essentially unplayable. The single player mode however, runs just fine on identical settings. Now, I did find a remedy (sort of). Turning off all the eye candy brings the game back within playable frame rate. The shadows, specular lighting, etc. What confuses me is that I purposefully turned these ON when I installed the game on the new PC. What confuses me is that just hours before, it ran flawlessly, now all of a sudden, it tanks, with identical video settings. My computer is more than capable of handling it on higher settings, as evidenced by the last week of it running wonderfully! I did however, also notice an identical issue in Metro 2033, which is the most demanding game in my collection. It played great yesterday afternoon, and now it tanks in open areas, yet corners, etc. provide normal frames and sound. I even reloaded the same level to get an identical test. However, Source games remain entirely unaffected.

I am a driver junkie. My motherboard chipset and audio drivers are all up to date, per the Evga support website. My video drivers are also up to date, having installed 260.89 last night. However, I have NOT updated or flashed my BIOS at all, which, when googling around for the initial sound problem, led many people with my motherboard to flash the BIOS, resulting in a fix for the issue. I think flashing the BIOS is my next step in the equation in hopes of fixing this issue. Let me know what you guys think. Any input/suggestions is appreciated. Let me know if I can provide you with any additional information or details. Thanks!

UPDATE: I stated in the OP that this issue does not occur during Single Player. That is false, the issue does indeed occur in SP.

✔ Best Answer
did u try to use generic driver(for audio)? Also check in bios if onboard audio is enabled, Did u try to reinstall v-card driver(un-install then restart the system and install the drivers)?

UPDATE: I have resolved the problem. While I had previously exhausted all driver possibilities by installing/reinstalling audio and video drivers over, your link to a somewhat similar issue inspired me to not clear the CMOS, but to simply reset the BIOS to defaults. Upon doing so... the issue was resolved! Metro and MW2 both run normally again. I have absolutely NO idea what was changed to have caused the problem but all is well now! Thank you kuwese.
