I've been having issues with playing Czech girls video files that are of the 1 GB size type. I have a GTX970 with Windows 7, Omen gaming monitor and a cheaper, but approx same size 2nd monitor. I see lag when watching these big files. The files load from a solid state drive. My computer uses Intel Core i7 5820k CPU @ 3.3 GHz x12. I have 16 GB RAm. For example I was seeing this just now and the only other thing I'm running is Chrome watching a youtube video. Any ideas?
