I recently acquired a second monitor and installed it with an HDMI cable. Since then TF2 has been choppy, even though I have high FPS and a low ping. Does anyone know how to fix this problem? My guess is its something to do with the second monitor. I have a GTX 760 that outputs to both monitors.
Specs: i5-4670k, 8 GB RAM, Windows 7. That should be everything relevant to this problem.
