I'm having a weird problem with Windows 7, a decent graphics card (GeForce GTX 650 Ti 1GB 128-bit GDDR5 PCI Express 3.0 x16), and simultaneously watching video and playing a video game.
I'm trying to watch a simple movie with a pretty low bitrate, and playing Fallout 3. My graphics card can easily play Fallout on maximum settings, but no matter what setting I put it on, the game plays smoothly, but the movie on the other monitor has a slight chop to it, like a stutter, about once per second.
It seems that there isn't a hardware bottleneck, as the graphics card, the i5 processor and 16GB RAM must be more than enough to handle the dual operations. I can't think of what I need to do to eliminate the stutter in the movie.
Any help would be appreciated!
