Is it possible....

[Phil]

That's not what I was saying! I was giving him an idea of that it IS possible to have a game run 30fps on a TV with 60hz controls. I didn't say the performance of a game is linked to the television. THe game could be rendering at a higher frame rat ethan that, and it would jus tdrop frames. You could sample the controls/physics/AI at whatever rate you want! 240Hz or higher if you have the processor time to spend.

Of course you can, but that doesn't give you more control precision. Updating the controls at a higher framerate has probably to do with the physics engine which requires higher precision. Strictly on the perception of precision, you'll only get the amount of precision that the feedback allowes for (meaning actual rendering framerate). I also would like to point out that even if the above technique is used for more accurate physics, that a higher framerate is still always preferable and better.

Well, the time between taking a sample and drawing the image determines the latency of the control, you can sample multiple times but only the result right before the rendering will be reflected on the display.

It would be pointless to sample controls more frequent than update the display unless the control samples are interpolated. This would lead to a smoother reaction, but would also introduce a delay. You'd trade precision and reaction time for smoothness, similar to how mouse smoothing works in a first-person shooter.

Dude, argue the TOPIC instead of SEMANTICS next time you reply to one of my posts! Anyway, I was talking about VISIBLE lines, which are ~240 per field, the rest is vertical blank, teletext and shit like that.

Quite a few actually. 480p/525p contrary to popular belief is not an HDTV resolution.

Ah, OK. Misunderstanding, then There's a large number of TVs today that can display full 60FPS. Pretty much every TV labeled with HDTV support can do it, both tube and plasma TVs. They all support progressive scan.

Cyba,
FCC defines 480p as a HDTV resolution, so I consider it as such It's often referred to as EDTV, though.

FCC defines 480p as an Extended Definition - as you mention yourself. Extended because it is a modification to the existing NTSC standard when there was a need for higher quality video and HDTV wasn't ready.
