I play SSFIV:AE on Windows 7, 64 bit edition. My video card is Radeon HD 5770. I have installed the latest drivers.
Sometimes, usually playing online (but not exclusively), with no apparent reason the game starts skipping every 10 frames and then showing next 10. My video card is quite noisy, but during those unshown 10 frames it stops chirping. What I get is an intermittent video (video stuttering). To fix this, I have to quit the full screen mode (Alt+Enter). If it doesn’t help, I have to mash Alt+Enter until it does. This never helps if the game’s resolution matches the Windows desktop resolution and always ends with the match (when the winning character screen is shown). It’s bearable, but very annoing.
I have no idea where to start looking for the problem. Any help would be appreciated.
