I have a problem with stuttering x264 playback with newest SAF 6.x (both on Cyberlink and ffdshow DXVA) with extended desktop configuration.
System ist core i5 & Nvidia GTX 560 TI - so performance should be OK.
If only one screen is used, playback seems smoother.
How can I get smooth playback with 2 screens connected - MP on the extended desktop?
I suggest you try v0084_part_DWM_dshowhelper, linked to here https://forum.team-mediaportal.com/...nter-dshowhelper-community-development-81148/
I use dual-screen (with ATI though) and had loads of stuttering problems until I used this.
