I have everything configured properly, and a decent gaming rig. After about 15 minutes of being in-game callouts stop being called in over the radio? I have no idea why, and LCPD:FR isn't giving me any errors in the diagnostics tool.

I'm using dsound.dll, and do not have xlive.dll in my root folder, I'm also using the latest patch 1.0.7.0

System Specs
Intel Core i3 2100 3.1GHz
Nvidia GTX 760 2GB DDR5
14GB DDR3 1333MHz RAM
2 TB 7200RPM HDD

I have 14GB's of ram, so I know that it isn't due to any memory issues.

Post all .log files please.

Despite you having enough memory, GTA IV is poorly designed. In some cases, this "memory leak" would lead to world textures dissipearing. By default, GTA IV can't even use more than 4gb of ram.

You can rectify this problem by installing Large Address Aware.  In adition, try to:

• Remove/Replace/Reinstall any traffic modifications; These may cause conflict with LCPDFR's spawning engine.
• Remove any high poly (models with lots of polygons) models.  This may also put a strain on GTA IV.
• Tone down graphics settings, in particular view/detail distance and resolution.
