IrfanView was able to load it in about 8 seconds (Ryzen 7 5800x) using 2.8GB of RAM, but zooming/panning is quite slow (~500ms per action)

IrfanView on my PC is very fast. Zoomed to 100% I can pan around no problem. Is it using CPU or GPU? I've got an 11900K CPU and RTX 3090.

  • There's fast and slow resample viewing options in Irfanview, he may have slow turned on for higher quality.
