I'm the new Lower Lab PC teacher at my school. I have 44 students at a time.
Sometimes I have my students test out educational games I've made. (HTML 5) (GameMaker Studio)
Noticed 2 PCs were running my games in extremely slow motion.
Updated their drivers...Cleared Cache...yet still no improvement.
The PCs have good Specs: 64 bit HP Win 7 AMD E1-2500 APU with Radeon HD 1.40GHz 4GB Ram
My games are really basic (2D) and can even run well on old single core Win XP PCs (500mb Ram)...
...So I'm not sure what the problem is.
