That will be difficult, because there is no standardised way for games to advertise their system requirements, so the software on your PC doesn't know.
Let's say that Flash games always work. Alas, Flash is on its way out. Maybe switch to gaming apps on your phone or tablet?
can you suggest me a website/software which can help me in downloading suitable games which can run smoothly in my pc by understanding my system hardware capabilities.
THANKS IN ADVANCE.
all helps are appreciated
