Open CL, Graphics Cards and faster previews
I have been wondering why my previews in 6.1.1 are not as lightening fast as I hoped, and found that 'Use Open CL' is grayed out in C1 preferences - any idea why? I am on a windows 7 64bit system, 24Gb Ram, 980X 6core processor, etc, all high end.
I thought my Video card would be supported as its a recent FirePro V4800 1Gb one but it seems it is not on your list (KB: 1720). You have the non pro 4800's there, but no the pro V4800 - why is it not supported?
I am hoping not to have to buy a new Graphics card 5 months after I bought this one! I need 10bit support for my monitor (and the future) so its an expensive upgrade if so.
ps: I also see contradictory statements in that KB article:
"Setting the preference to "auto" enables the feature, if you have enough GPU cores"
and then:
" Dual GPU cards are supported only in single-GPU mode"
so which is it - more GPU cores or one core?

GPU cores refer to the CUDA cores available in the video card. For example Nvidia GTS 450 has 192 CUDA cores. 0 -
Video card capabilities are largely controlled by the drivers, and Win 7 drivers for Both ATI and NVidia have been frequent for the Win 7 64 OS....the latest for my Radeon card was this month, looks like the latest for yours was Feb this year.
If you haven't installed the latest drivers, you might not have Open GL installed on your card, the standard ATI driver 6 months ago needed addon software drivers to support Open GL on my 5770....seems to be included in the current versions.
Hope that helps....0 -
I'm (now) using 64 bit Windows 7 on a 3 day old machine with an i7 950 processor, 12 Gb of RAM and an Nvidia GeForce GTS 450 Golden Sample Graphics card and I am also surprised and a little disappointed to notice that my previews are slow in appearing. I thought it would be instantaneous. This is when viewing files from a D300. Open CL is enabled on Auto.
I think there are loads of bugs in this software, which I find infuriating0 -

If switching OpenCL OFF does not make it slower, OpenCL is effectively not operating. Contact support in that case for going through the basic checks of drivers and so on.0 -
Instantaneous is a very high expectation...<g>...also, a part of the initial preview generation is writing those previews to disk. I find the overall process benefits by changing some of the default settings in Win 7...such as indexing and constant defragging. Google Win7 speed tips...optimizing the OS can have a huge effect...
Also, check your driver (unless you have done this already) NVidia has a great online driver update...and the latest release made asignificant difference on my CPUs. A computer built and tested over the last week might not have that very current driver..
It's my observation that COne functions VERY slowly while files are being copied/transferred...that difference is very pronounced even when the files are not involved with COne focus.0 -

I second that observation. My Core i7 950 system has a lousy lazy cheap nothing but boring graphics adapter but only SSDs, no HDDs. And it is a fast CO system for sure, whether I am adjusting during processing or without processing.
No doubt a better video card will be the icing in the cake but I am happy so far.0
