The 64 bit version is higher resolution, for 90% of computers.
You only need to use the 32 bit version if you are on an older computer (Windows 7 or no add-on graphics card. Some on-board graphics cards have difficulty with 64 bit games).
So try the 64 bit and if it runs smoothly, you're solid. It should be 100% if you have 32GB ram and run Windows 10 or 11.
