That is most noticeable when there is a lot going on with large numbers of personnel and machines, load screens and movie excerpts. The problem is the game bounces back and forth from virtual to physical RAM for graphics pulls. Then you have most likely been getting freeze-ups and or slow play at very least. If you have downloaded origin's free release of CC Redalert 2 and Yuri's Revenge, but have a newer operating system like 8 or 10. This is the fix many of you are probably waiting for!
