Random slowdown bug plagues GeForce 8800 cards

Late last month, a TR reader who calls himself Cybercat alerted us to what he said was an inexplicable problem affecting some GeForce 8800 cards, and particularly the GeForce 8800 GTS 320MB. According to Cybercat, the problem causes random slowdowns, often halving frame rates until the user alt-tabs out of the game and back in again. More interestingly, the problem doesn’t appear to be tied to any particular hardware configuration, Windows version, or display setting. Users with all kinds of setups have been reporting problems, from the Nvidia and eVGA forums to the NVNews, Rage3D, and Guru of 3D forums.

We decided to contact Nvidia about the issue, and Nvidia Technical Marketing Director Nick Stam has now gotten back to us with the following message:

Sorry for delay, took a while to gather info.

We are aware of this issue and our driver team is working on it now.

We expect a fix some time in July.

That might be too late for some, though. Cybercat says a number of users have already given up and returned their cards since the issue began cropping up. It’s not hard to understand why, either: the oldest forum thread we could find describing the problem dates back to February of this year.
