![]() Card memory is not just used for the frame buffer, plenty of driver stuff gets loaded into it as well. “Actually I’m not sure as that’s not a simple issue with just one cause. PeterS provided more detail in a follow-up comment: We’re working on a driver update that will tune what’s allocated where in memory to further improve performance.” The GTX970 is an amazing card and I genuinely believe it’s the best card for the money that you can buy. “It sucks because we’re really proud of this thing. Writing in the GeForce forums, an Nvidia employee and moderator going by “PeterS” said the following (emphasis mine): But an Nvidia representative says the company is working to minimize the issue regardless.

In cases where games need more than 3.5GB of RAM, some users saw stuttering and frame rate wonkiness as the GPU accessed the 512MB segment. The GPU actually taps into two separate memory pools: A primary, full-speed segment of 3.5GB, and a secondary, far slower 512MB segment. To make a long story short, Nvidia was recently forced to admit that the way the GeForce GTX 970 handles its 4GB memory allocation is… unorthodox, to say the least. There’s trouble a-swirling in graphics land. This post originally ran at 2:30 PM Eastern on 1/28/13 with the headline “Nvidia plans GeForce GTX 970 driver update for memory performance concerns.” The original post follows in its entirety. Any improvements we make in our drivers are designed to help all GeForce cards. NVIDIA GeForce January 29, Miscommunication on our part. We are always improving performance through drivers but there are no plans for an update specifically for the GTX 970.
