Weird observation with gameplay smoothness with interlaced vs progressive

Emig5m · 01-14-2012, 03:47 PM

Initially when I tried this game on the PC I thought it ran like complete crap. Later I tried it again on my new system and when I was routing my video through my Asus Xonar HDAV 1.3 soundcard I noticed that the game was defaulting to 1080i@30fps and not 1080p. Normally 30fps would be juddery looking and laggy with control input but to my amazement it was as smooth as watching a movie with native 24hz support with all your devices. No judder, liquid smooth video animation, and liquid smooth control input. If you had no idea the game was internally locked at 30fps you would have sworn it was running at least 150+fps.

Later I bypassed my Xonar and took it out of the chain because it's the original that didn't support 24hz movie playback and currently using my nvidia GTX 560 for HDMI sound but now no matter even if I manually set 1080/30i once the game starts it defaults back to progressive (1080/30p). Now the part I hate, although the graphics seem a little sharper when in progressive scan, now the video looks really juddery and flickery like running a low refresh rate on a CRT display. Control input is also effected in a similar way. It no longer has liquid smooth control response and video is really juddery.

Now the question begs, why does using interlaced produce perfect video playback (animation wise) and butter smooth control input to where it feels and looks like playing Quake III arena back in the day at 200fps? And when using progressive, boom, juddery and un-smooth video/animations and laggy control input. Did using interlace somehow bypass the games internal framerate lock? I mean it was so smooth when in interlace mode that it nearly looked like the soap opera effect on 120hz+ LCD displays... and the smoothness of the control input was unreal. Major difference over the laggy feeling xbox 360 version. But now stuck in progressive, feels and looks worse than the 360 version....

Ideas as to why this is and perhaps a fix?

Disregard my idea of interlaced vs progressive. It wasn't that. Once switching the game setting to 1920x1080/60hz from 30hz all is smooth in 1080p with the display set at 60hz. My bad.
