NVIDIA Stereoscopic 3D Driver Service Has Memory Leaks
Rafael Rivera, a Windows hacker, has find a memory leak that seems to affect all owners of 3D glasses that use NVIDIA display drivers series 186.xx and up (driving a GeForce 8+). The guiltly of that memleak is the stereoscopic 3D driver service (nvSCPAPISvr.exe) that does many calls to SetupOpenInfFile() without calling SetupCloseInfFile(). Handles returned by SetupOpenInfFile are never released by SetupCloseInfFile leading to a large memory consumption.
If you don’t use 3D glasses, it’s highly recommanded to stop and disable the NVIDIA stereoscopic 3D driver service.
NVIDIA is currently investigating to see if this is a real issue…

OMG an application has a memory leak… Now that’s something ne- no. not really.
It’s not an application, it’s part of the video drivers. And it’s not a particularly small leak either. In 3.5 days it had leaked nearly 900 megs on my system. For part of a WHQL-Certified driver that’s pretty ghastly.
