I've been pricing out a switch to a full frame 45mp mirrorless rig and have gotten around to processing. My current PC is a Core I7-8700 w/16gb DDR4, two fast M2 drives and a Nvidia 1660 Super w/6gb DDR6 running all lanes on PCIEx3. ON1 and Win10 are all tweaked for performance and it does pretty well with 30mb (+-) raw images from my 24mp Nikon up to 4-5 layers. I downloaded several 55-60mb (+-) raw images from the internet to test ON1 with files that large and found the performance turned south quickly and frankly ON1 became unusable with multiple layers added to the original image. The full frame 45mp images quickly increased in size up to 275mb of course. I run task manager on the performance tab and watching the free system and video memory, GPU, CPU all looks good. CPU is low, system memory gets used as well as GPU memory and but not too excessively. The GPU definitely runs to 95-100% frequently but that I believe should be expected. I'm sure some folks here must be using a high megapixel sensor camera and am wondering how their ON1 performance is and is it fairly snappy with good brushing capability? If so, would you mind letting me know what your system specs are so that I can make a comparison? I suspect that a move up the Nvidia tree to an RTX 3xxx-4xxx series would make a big difference but am wondering if possibly the huge file sizes of these image files may simply be too much for ON1. Thoughts/comments are appreciated!
