Yea mid-tier is a stretch. Maybe low-end gaming

Low end gaming ia 2d indie titles and they now run on toasters.

All the popular mass matket games work on iGPU: fortnite, roblox, mmos, arena shooters, battlen royales. Good chunk of cross platform console titles also work just fine.

You can play Cyberpunk or BG3 on damn Steam Deck. I wont call this low end.

Number of games that dont run to some extent without dGPU is limited to heavy AAA titles and niche PC only genres.
