I recently bought PureRAW 2 to batch-process my images with DeepPRIME and noticed it felt pretty slow. In the past I used PhotoLab 4 to process my images but it felt even slower than that.
I looked at Task Manager and noticed that neither my CPU nor GPU were anywhere close to fully utilized. Most of the time, the computer was barely doing anything.
I wanted to see if PhotoLab 4/5 really were faster and/or making better use of my hardware, so I took a set of 60MP ARW files from my Sony A7RIV and processed them with both pieces of software, recording my computer’s CPU/GPU load at the same time.
Here are the resulting charts:
You can see that the orange line for PureRAW 2 is close to zero around 2/3rds of the time, this is because it’s not touching the GPU at all. PhotoLab 4 and 5 on the other hand both keep the GPU occupied at nearly all times.
The practical result was that I was right: PureRAW 2 is much slower than PhotoLab, both 4 and 5:
|Program||Time per image||Mpix/s|
My PhotoLab results are pretty close to others on the DeepPRIME benchmark spreadsheet, PureRAW 2 seems to be the slow oddity.
So in my opinion, avoid PureRAW 2, buy PhotoLab 5 instead.
I’m working through this with support and I’ll update here if they offer any fixes.
