Number of CPU cores used

[superbarney]

I am using an AMD Threadripper 1920x CPU. The "About JPEGView" dialog box shows 1 core used when the "CPUCoresUsed=auto". I can set it to 4 which is the maximum allowed by the program.

If say in the future, JPEGView supports a higher number of CPU cores used, will this improve the time it takes to display a full RAW file?

Thanks.
