Gtx 970 performance issues

[thisguyiknow]

I have two different hackintosh computers - one with a low end gtx 650 in it and another with a gtx 970 in it - both work perfectly using the NVIDIA web drivers (i.e. it seems stable) -- The issue I am having is that the performance of the 970 during opengl extensions test is only a quarter of what I am getting from the gtx 650-. Is this because the 900 series are not explicitly supported in the NVIDIA drivers so they do not leverage any of the hardware advantages between the two?

Thanks in advance

Cheers

The 900 series cards are supported by the Nvidia Web drivers. You should be getting fine performance from those. If you do not have the web drivers installed then you will get very poor performance from the 970 when booting with nv_disable=1.
