Hi, thanks for looking.
I've just bought a 5D Mk4, upgrading from a Mk2.
Ive always used DPP3, I had tried DPP4 prior to my camera upgrade, found it painfully slow with the 5D Mk2 raws, so reverted back to DPP3.
DPP3 doesn't support the 5D4, so I have no choice but to use DPP4.
I'm finding DPP4 painfully slow, it takes several seconds for changes to take place when I make any adjustments, and to convert a Raw to Jpg takes around 40 seconds, this is going to add so much time to my edits when I'm doing weddings, that I'm considering sending the camera back.
My PC is around 6 years old, but was high spec when I bought it, it has an i7 quad running at 3.2ghz, 12gb of DDR3, a solid state drive, and a high end GPU.
When I look at the CPU usage during a Raw Conversion, its constantly spiking to 98%.
I've never had a problem with my PC, has run everything smoothly since the day I got it, DPP3 is instant, Raw files convert in 6-8 seconds, slider changes are instant. As I previously stated, DPP4 is slow regardless of whether I'm converting Raws from my Mk2 or Raws from my Mk4, I don't believe its anything to do with the size of the raw files, just the program software itself.
Any advice would be massively appreciated.
