I'm new to these types of boards so if there's any sort of metrics you need me to get, just let me know and I'm happy to repost. I'm running on an I5-3570k CPU, and the GPU is a Radeon HD 7950 all on a Windows 8 platform

Something relatively new has started happening when I watch movies. It always starts out perfect, but after a few minutes, the video starts to get choppy and the audio stays fine but the video gets out of sync. The weird business is when I rewind 5 secs, it puts it back right into alignment and it looks normal again for a few minutes till it starts doing it again. Another thing to note is that I play video games, and while I don't have anything recording any metrics, I haven't noticed anything slowing down graphics wise.

I thought it was the video player (Zoom Player Free), but I tried upgrading it and even switching to VLC and WMP, but the problem remains. Then I tried updating the drivers, but that didn't work. Then I switched to the beta drivers. All the while, I've been constantly restarting. 

Running the AMD System Monitor, I can tell you that when the lag spikes happen during video, the Memory Speed and usage go all the way to the 90-100%, but I don't know why. Also, the GPU temp stays an average 33C, which I assume is a fairly average temp.

Possibly a codec issue? Try configuring the players to use DXVA (gpu acceleration), for best possible results try MPC-HC with EVR custom or madVR+LAV (more complex to configure, but the result is amazing).

There is a single download on this site  (http://imouto.my/configuring-potplayer-for-gpu-accelerated-video-playback-with-dxva-or-cuda-and-also-high-performance-software-decoding/) that will use potplayer (my choice) with LAV+madVR, and it is all pre-configured.  Personally I like to configure potplayer myself, but the site above does make it stupid simple 

Also if you have a decent CPU, software decoding is the easiest and the best picture quality

Holy googly-moogly! That was a fantastic recommendation. Not only did it solve my problem, the video quality has never been better. Thank you very much

And it actually can get better...  If you can run Jinc 3 with Anti-Rining for Chroma and Image upscaling in Fullscreen Exclusive nothing compares.

 

That pre-configured "mega" pack is set in such a way that it should run on almost any GPU.  My 5770 runs Jinc 3 w/AR no problems

 

To learn more about madVR and how pwerful it can be here is the development thread:

And here is the development thread for LAV:

Or if you are happy with plug and play you can just follow the page I originally linked to.
