You didn't give most of the system specs you are supposed to give when posting a question so not sure how many potential contributing factors could be playing into your current experience but regardless the people helping in these forums are fellow users only NOT AMD.

Keep in mind the minimum means it will run but likely at low resolutions and low graphical settings. It roughly half of what is required to run. You can see here the performance comparison of your graphics vs the minimum graphics card. Yours is a mobile gpu and those are pretty lac lust until recent changes such as newer systems now with Vega graphics that do much better than mobile graphics used to. While that card is way older than yours it is still far more powerful as it was a top tier card. I would add that your card really is below even minimum spec to run that game.

That being said if issues are caused by something broken in the drivers then yes that could and should be fixed. There have not been any real performance improvements on that series in the drivers in years now. I would not hold my breadth on the your card ever getting any better optimized for that game as that card is many generations old now and is likely already as optimized as it is going to get. Having the game loaded on a SSD helps this a lot. The game also will load levels dynamically ( unlike the games you mentioned that run well, they load the whole level at one time before play starts) and you see these frame slow downs because of this when advancing from area to area when driving or flying a lot. It really is a game that benefits from having 16 gigs of ram. It also is very memory hungry it absolutely will not run well on less that about 12 gigs of system ram. I will be honest while that is a great game, it is very demanding on even the best graphics cards. Use "MediaCreationTool" to download current win10 ISO from M$ and do a clean install. On the other hand, mostly a complete and clean OS setup can fix various things. As normal users don't keep full system backups (I did for some time, but at some point it became a waste of time) to restore to a specificpoint in time, I guess this will be not a possible option for you. To test, if possible, the system should be set to a state when it was last working and compared to what's currently different.

So, when for what ever reason, the switch does not occur but everything is only run on the IGP, aside from a critical hardware error, it's either a driver problem (maybe even caused by windows updates) or cause the application doesn't make the api call needed to do the switch.

The switching is operated by driver instructions (that's the reason why you have to install both the IGP drivers and the dedicated gpu ones) initiated by some standard api wich has to be called by the application. Usual, when you have an Intel cpu with an IGP and a dedicated graphics card, it works this way: The Intel IGP is connected to the display and switch between either its own graphics cores or just redirects the input comming from the dedicated gpu.
