It can be seen directly from the opening pictures of the two games that Loneliness 2 is the trademark of NVIDIA.
Loneliness 3 is a trademark of AMD.
This game is made by sponsors, and whoever pays will be optimized for it. The second generation was also sponsored by Microsoft, and the Microsoft NVIDIA Intel Alliance left a deep impression on the second generation. If your cpu is not Intel but AMD, and the graphics card is AMD's 6670, it is normal to play solitaire for 2 hours.
Besides, your framework requirements are really low. Play "Zhong" of Orphan 3 of 1280* 1024 in 6670, with a maximum of 40 frames.
