Re: GTX 480 - High DPC Latency

The problem of high DPC latency for your machine after the upgrade of gtx 480,but this kind of problems were mostly faced by the video cards due to the drivers of the nvidea,this issue is just due to the conflict between the hardware and driver conflict.The Conflict might be between motherboard and audio drivers.

This problem is on windows vista,W7 seems to use the same driver as Vista as well,the high DPC latency spikes cause a lot of interference in the smooth playback and recording of audio,you may use it by keeping the driver of,W7 is a bit better with DPC latency than Vista but still for a lot of people unusable with this driver on.
