Question / Help lag with CPU encoder, fine with GPU encoder

15:04:48.042: Output 'adv_stream': Total encoded frames: 5955
15:04:48.042: Output 'adv_stream': Total drawn frames: 6043
15:04:48.042: Output 'adv_stream': Number of skipped frames due to encoding lag: 2436 (40.9%)
15:04:48.042: Output 'adv_stream': Number of lagged frames due to rendering lag/stalls: 2059 (34.1%)

Your CPU is being overworked between the stream and game. Witcher 3 is a fairly 'heavy' game, too. No idea why the CPU load showed that low though, unless it was thermal-throttling. What do your temps look like? Also, are you restricting the game to certain CPU cores, and OBS to other cores from the Task Manager?

Also, this is the forum for OBS Classic, the old windows-only codebase. The Studio forum is up a level or two and over under the Studio section. :)

i made a screenshot http://imgur.com/download/uw1z261

and the game and obs is not restricted to my cores.

That shows your CPU running at 80%+. OBS is misreporting the CPU usage in the infobar is all (or reporting its own usage? I don't know, I don't use Studio)

In short, yes, your CPU is being overworked. Try forcing Witcher to specific cores and OBS to other ones. Also, Witcher is a very visually-cluttered game, which means a heavier encoding load. You may have to dial it back to a 480p stream, with the combo of a CPU heavy game and more demands on the video encoder.

i changed the preset to veryfast now, it seems to be fine now but sadly allot of quality loss from the fast preset :(
