In early August, I documented a handle leak that had existed in NVIDIA’s Forceware drivers for some time, affecting all of their newer GPUs. Yesterday, NVIDIA released a new set of WHQL drivers versioned 190.62. In a typical sweep-under-the-rug fashion, NVIDIA made zero references to the issue in their release notes. Having scanned the disassembly of nvSCPAPISrv.exe, however, I can confirm NVIDIA has fixed the problem by calling the appropriate function I suggested. AMD’s fastest GPU – the ATI Radeon HD 4870 X2 – continues to be unaffected by this issue.
You’re welcome, NVIDIA.
