EDIT: If somebody is going to down vote me, ok. But at least follow up with WHY you disagree.
It wasn't me who downvoted you but speaking as someone who has a W7 rig, I'll give my two cents regarding
that confusing chart. In reality, such charts offer an extremely dumbed down and regularly contradictory "guide" as to what to expect. Eg, as long as the DX11 or Vulkan API is an option, it should run fine on W7 in general and not be limited purely to "min preset" as that chart portrays (that's just a rough guide for how a GTX 1050 2GB would perform, not an upper preset, hardware or fps limit for W7 / DX11). Min to Ultra presets include GTX 1050 to GTX 1080Ti and i5-4440 to i7-8700K all of which work on W7 and cover the bulk of the PC gaming install base. If the game gets 60fps on both an i7-4770K and a i7-9900K, then given the logical assumption that no sane developer is seriously going to write 5x different sets of AI or sizes of levels (4x PC + consoles), then all the "core" stuff like physics, AI, audio, will probably run on the 4770K at 60fps (plus console CPU's) with much of the higher preset premium being on additional stuff that can be scaled up / down without much extra coding work, eg, increased draw distance or 144Hz gaming on 6-8 core chips.
The bulk of W7 gamers tend to use 1080p to 1440p monitors + no ray-tracing which instantly kills off the need for RTX 2080Ti that's the only W10-only hardware listed that doesn't have a W7 compatible equivalent. And of course, 4K Extreme / 1440p Ultra / 1080p High - these presets and resolutions aren't really tied together. You could run 4K High or 1080p custom High/Med mix with a weaker card. Many "xtreme" presets are regularly dumb and unoptimized in many games. Eg, Skyrim's Ultra = 8x MSAA + FXAA combined. Disable MSAA and use only FXAA and you can add +50-70% fps on low end cards right there with little visual change. "Proper" benchmarking sites don't like to use anything other than "pure" presets, but many gamers more interested in playing than epeen have long learned to ignore this, and a lot of us automatically turn off cr*p like Chromatic Abhoration, "Eye Adaptation", etc, anyway purely for their sheer dumbness / uglification regardless of performance. Finally contrary to Microsoft's dishonest fear-mongering, with the right chipset (Z370, H310 R2.0 or B365), 6-8 core Coffee Lake and Ryzen CPU's do indeed work on W7
including the quoted i7-8700K with the only caveat being a dGPU is needed (Coffee Lake iGPU & Raven Ridge APU's don't work).
tl:dr - As long as the game has a DX11 / Vulkan API option, then Metro Exodus is likely to be entirely playable on W7 with a GTX1060/6GB and above cards and a little tweaking.
