Basically it enables the windows features 'Virtual Machine Platform' and 'Windows Hypervisor Platform'.

I have been following those instructions exactly. You can see exactly what I am doing by reviewing the WSL Installation Guide for Windows 10. I am giving you these reports directly from my Windows machines, and not a VM. From what I know, Windows 10 does not support Hyper-V but it does support WSL2 via the 'Virtual Machine Platform'. I have a Canon 6D and the out of camera RAW files tend to be around 25-27MB.I'm not running any VMs except those that are pre-configured to run Windows Subsystem for Linux 2. I'm actually away at the moment visiting friends, but what I might do when I get back is see how many RAW files I'll need to open / edit before the lag kicks in. The one I went for was the 8GB / 256GB without the touchbar.

Anyway, I absolutely love it and saved myself £1000 because I almost got the 15' with touchbar (which is an amazing computer to be fair). I often have half a dozen RAW files open at any one time, and I've also yet to encounter a situation where the screen size has been an issue either (which I thought might be the case with the Adobe Illustrator work that I do - although in fairness I do have a large desktop monitor if this ever did become a problem).

Because my 15' pro had a separate graphics card I was worried having an integrated one would cause problems, but it doesn't at all. The 13' pro has a different / better processor now to when it first came out as well. The MacWorld site said it's not the best choice for creatives (in comparison to the 15', which is an obvious thing to say), but they are assuming 'creatives' will do a lot of intense 3D and Video.

So I thought I'd provide a real-world answer as opposed to being just another 15' user taking a guess. I did a search for this question yesterday because I couldn't decide myself for a couple of months and there weren't any real answers.
