Slow Frames in 1080P

[hydr0]

Hello all. I did a little searching, but didn't see anything that could fix my problem. Anytime I watch an HD movie on my comp, it reallllllllly chugs. I'm not sure if it's Win7 or my new video cards that's causing the issue, but when I was running Vista with my old 8800GTS (SLI) I had no problems at all. Videos ran smooth as butter. Now, after an OS upgrade and video cards upgraded, the movies seem to really chug. Sometimes it's OK, but anytime there's something going on onscreen, it runs like crap. As for codecs, I've tried FFDshow and Core AVC Pro, to no avail. As far as players, I have Zoom Player and VLC Media player. Neither of them is playing these movies right, whereas I had nooooo problems at all before. Can anybody point me to any settings, maybe in NVidia control panel, or CoreAVC, or wherever, that'll help me with this? Also of note, my video games run with no problems at all, even on 1920x1080 resolution and all settings maxed out.

i looked through the nvidia control panel and couldn't see any settings that might impact your system the way you describe, the only thing i could think of is under the section titled "adjust video image settings" you have settings for adjusting "edge enhancement" and "noise reduction", and you can choose to set a global setting or letting the video player choose, check to see if you are allowing the player to choose.

also try using the cccp codec pack, it's based on ffdshow but i have found in many cases it works a bit better and doing a quick search through the win 7 forums as well as a google search shows that quite a few people seem to be having issues with win 7 and sli, part of me wants to say that the win 7 sli drivers aren't fully baked yet, try disabling sli and see if that fixes the problem, if it does you have your answer.

VLC uses its own internal codecs and they are single threaded. 1920x1080p24 or p30 h.264 video will not play smoothly with that. I don't know about Zoom Player. Do the ffdshow or CoreAVC Pro icons show up in the System Tray when you play your videos with Zoom Player? If not, Zoom Player may be using a single threaded internal decoder too.

Try using MPCHC. Be sure to enable its internal h.264 docoders (ffmpeg and DXVA) and make sure the ffmpeg decoder is set to 4 threads. While playing a video you can right click on it and hover over the Filters menu item to see what filters are in use. You can select the filters to set internal options.

Also, make sure you have a recent multithreaded h.264 ffdshow installed and are using ffmpeg-mt, not libavcocec. Older versions are single threaded.

Thanks for the quick replies! I just found a workaround a few minutes ago, though it's a bit of a pain. I watch movies on my big screen using dual view. By disabling my computer monitor and just using my big screen as primary, it alleviated the problem. But I love to browse around on the web while I'm watching a movie, so there goes that. I'll give the above mentioned suggestions a try next. Thanks guys =)
