What's the difference between SSE3, AVX, AVX2 and what should I install?

The releases are very confusing, what exactly should i install for Win-11 64bit?

What's the difference between SSE3, AVX, AVX2, and when are they used?

From order of fastest to slowest: AVX2, AVX, SSE3.

For sake of your own sanity, install the AVX2 one first, if it runs, you're all good, else try AVX then SSE3. Basically, CPU's are evolving and newer CPU's will support newer instruction sets, whereby, you can do more advanced math using fewer CPU cycles.

Great!
I have no idea what CPU is simulated in the Virtualbox VM, where I have Windows-7 running.
I tried all, but I could not get anyone to work there. Clearly I must be doing something wrong.
