Bad Performance using GTX660 & i7-3770k

There is no clear troubleshooting step for crashing issues but we got several responses from our community that some of following steps worked to solve the issue:

• Nvidia – Reverting to older drivers  - GTX 690 - 331.65 crashed non-stop. 331.40 beta from sept and in 3 hrs not one crash. Another player mentioned that rolling back to 331.58 stopped his crashes.
• Setting In-game audio to headphones.
• Update Direct X and Microsoft .NET Framework
• Disabling NVIDIA High Definition Audio (Single Player)
• Run as administrator (for BF4 and BF4x86). You could also try changing security permissions on the origin games folder giving users full control instead of just read
• Nvidia Control Panel > Configure Surround > PhysX > PhysX settings > select your graphics card. Then Origin > Repair Install, played all day without crashing. Another confirmation and another.
• Punkbuster Uninstall / Reinstall
• Microsoft Visual C++ x64 and x86 versions of 2010 and 2012 uninstall. Reinstall with Visual C++ Redistributable for Visual Studio 2012 Update 3 Second Confirmation
• Lowering settings from ultra/high to medium in x64 or low in x86 fixes the issue, always happening when Vram fills up to about 1.6 GB of VRAM.DirectX updates/fixes mentioned did not help. Confirmation by another player
• Stopping overclocking on Video card - SP only (e.g. GTX460)
