3GB Radeon HD7970 only showing 2048MB?
« on: September 06, 2013, 06:05:52 AM »
I just noticed that my 3GB Gigabyte AMD HD7970 cards are only showing 2GB in PhotoScan, while they show 3GB in the Catalyst control panel. Anybody else have this issue? Just started playing with 1.0 beta.

Its been like this for as long as I can remember.  I also posted about it some time ago.  Not sure if it causes any performance decrease...

Hello andyroo,

In the OpenCL tab PhotoScan shows memory that is available for OpenCL computations and not the whole amount of RAM for current device.
