Thanks a lot again! Yes I am using madvr settings from an older version! I will start with a clean sheet and try as you said!

In any case, as far as I know, with a 1070 you will be able to have smooth playback. It's all a matter of troubleshooting and selecting the correct settings for madVR. Be patient, it'll pay off.

Thanks for the motivation :-)

I did indeed test a lot last evening, using frame rate render time to find the madvr settings that give acceptable values (35ms or lower).. I was able to get smooth playback of H265 content now, but only when I set image upscaling to DXVA2, anything else will cause render time higher to much higher then acceptable (>42ms). See screenshots for madvr settings that work with acceptable frame render times. I do not understand why image upscaling settings make a difference anyhow on 2160p content since it does not need to be upscaled. Can someone explain me why this is?

Is it normal for a GTX1070 that it can smoothly render hevc only when setting image upscaling to dxva2?

Rather than using profiles in Madvr, use Dsplayer to set profiles through its own database (did you set those profiles up with an earlier version of madvr? if so,it might be trying to upscale/supersample 4k content. Goto dsplayer,system settings, player, scroll down to dsplayer, and select manage madvr with load and save with dsplayer database,Then play a 4k clip/movie, press M and gto into the scaling settings on screen whilst the clip is playing and chose your profile and save per resoultion (sd, 720p, 1080p and 2160p).
