I'd also discovered that the game runs -- slightly -- faster on my GTX 1050ti, albeit not much. Having played the game for so much now, I think they should be more inclusive here given that cards popularity in their specs. A GTX 1050ti is perfectly fine for playing the game at 1080p (albeit not at 60fps, naturally).
Recently seen this vid of somebody actually playing this on a 940 Mobile (albeit on lowest settings, which is not particularly pretty -- nor performant at such fps). https://www.youtube.com/watch?v=SBwsEciUmIg
Someone did a really good recording on a 3200G using the Vega 8 graphics, it was mostly 27-28 FPS at 1080p very low but with Vulcan so that's a bit better than mine.
I've seen the 3200G at £80, and currently cannot find any discreet GPU worth buying at that price point (GT 1030s dont have Display Port, Radeon 550s are currently inflated as they have always been the best cheapo card for a while now with modern outputs).
The Intel 9100F can be bought for £65 for a very strong quad core CPU, but without a GPU it is useless for gaming compared to the 3200G.
I wouldn't advise a 2c/4t anymore instead of a 3200G or 9100F for a new budget build.
