Flash player On Newer Systems

This game i play called Darkorbit has a 2D mode that rely's heavily on flash. It seems though my core i5-6600k cant seem to keep it at 60 fps. when comparing this with other people, it seems people with older systems have no problem running the game at 60 fps consistently. for example, my friend has a core i3-6100 and windows 7 but has only 4 gb ram compared to my 8 gb ram and i have windows 10. am i missing something about flash player? its all up to date, ive tried 100 browsers, ive tried older versions of flash as well. It just seems to studder at times and lag a bit. Idk what i can do to help it.
