Instructions:

Install the latest git for windows if you don't have it already: https://github.com/git-for-windows/git/releases/download/v2.45.2.windows.1/Git-2.45.2-64-bit.exe
Download/unzip the 3 standalone builds to test:

Generic x86 (all 64-bit CPUs / Windows 7-8):

https://github.com/Benitoite/RawTherapee/releases/download/nightly-github-actions/RawTherapee_genericwin_win64_release.zip

SandyBridge-IvyBridge (circa 2011-2015 / Windows 8-10):

https://github.com/Benitoite/RawTherapee/releases/download/nightly-github-actions/RawTherapee_midwin_win64_release.zip

SkyLake-RaptorLake (circa 2015-2022 / Windows 10-11):

https://github.com/Benitoite/RawTherapee/releases/download/nightly-github-actions/RawTherapee_fastwin_win64_release.zip

Run Powershell and cd into the RawTherapee program directory you would like to test. Pro Tip: type "cd " (cd then space bar) and drag the folder onto the powershell window, then press return.
Run the one-liner script above: (simply copy and paste into powershell and press return.)
Repeat Steps 1-2 for the next build.
Post the results of your tests in this gist in the following manner (each report should be surrounded by three backticks):
