I recently got my 15MP 50D. The larger file-sizes seem to be choking my PC using PS CS3. After previewing a couple dozen images with the loup, Bridge tells me it is out of memory. I have 3GB of RAM, dual core AMD Opteron processor, a large scratch disks, and large pagefile disk (separate volumes and channels).
Has anyone else seen these kinds of performance issues with the larger files of the newer DSLRs?
I wonder if CS4 would handle these problems better, particularly with the enhanced GPU support?
P.S. Has anyone seen any attempts to quantify the CS4 improvements from GPU support? I have been unable to find any robust testing of this new feature?
