Checklist

I have searched for a similar issue in this repository and did not find one.
I am using an official build obtained from releases or updated one of those builds using its in-app updater.

Describe the Bug

Certain users including me noticed that any version above 0.6 doesn't start. When we click on exe just a empty console appears and closes without error in log. You usually offer to install Microsoft Visual C++ Redistributable packages or update graphics card driver, but it turned out emu uses instructions above minimal.

I remembered about Intel SDE and tried to feed your emu v0.9 Qt GUI to it. This is result of my research.

I have i7-880 CPU (Nehalem) and it's match to your minimal requirements from FAQ.

CPU:
    A processor with at least 4 cores and 6 threads
    Above 2.5 GHz frequency
    AVX2 support (not a hard requirement, but strongly recommended for good performance)

Um... I understand that changing system requirements is easier, but... how about understanding what exactly emu use at startup and making it optional?

Reproduction Steps

Just run exe on any bad CPU families from my table.

Expected Behavior

I expect emulator to display its main window.

Specify OS Version

Windows 10 Pro x64

CPU

Intel Core i7-880

GPU

AMD Radeon RX 570 4 GB

Amount of RAM in GB

I don't know why the site only mentions optional AVX2 (which is outdated as it is now required) and not any other extensions, but your CPU will never run shadPS4 because you need at minimum some instruction sets that PS4 games themselves use including AVX.

The requirements are up to date in the GitHub wiki now. I am not sure about the site though, someone else will probably need to update that.
