So,updated from LR 1.4 to 2.2 (and cameras to 5Dmk2+1dmk3) and noticing that the picture rendering speeds (in zoom and developing module) are starting to get longer. Not unusable but slows down the workflow. Is the LR 2.2 gpu accelerated,would I benefit from a new gfx card like 8800 or such? Presently I have the old 7300gt wich is working otherwise just fine and dandy. Tried to find some info on the subject but didnt find any hard evidence about the performance gains. Only second hand yes/no babble.. Appreciated if you could chime in!
