Our colleagues received several inquiries from readers asking to find out what is the cause of problems faced by owners of 3D-card NVIDIA GeForce GTX 600 series on Kepler architecture .
Judging by discussion in forum, many have encountered defect in 3D-card NVIDIA's 28-nanometer graphics processors . Note that the problem manifests itself not in all cases, and depending on system configuration. Moreover, it is unclear exactly what combination of components results in a malfunction of the latest 3D-NVIDIA cards .
Associate asked for clarification from the manufacturer. Here is the official NVIDIA response :
We have received reports of intermittent vertical sync from some of our clients. We found that the reason lies in the error in the driver and found how to fix it. However, the correction requires extensive testing, so it will not be available until the next major driver update, scheduled for June (after R300). For users who encounter this problem, a temporary solution is to disable V-Sync in the NVIDIA control panel or in game graphics settings.
3D-card GeForce GTX 600 series technology support adaptive vertical synchronization (Adaptive V-Sync), which, as stated in our GeForce GTX 680 review, aims to improve comfort while playing . Probably, this specific problem is connected with Adaptive V-Sync .
