Top developers slam PS3 "broken" allegations

[zed]

Will lower frame rates cause motion sickness? There are some games which just gives me a total headache and queasy, while others are fine. I always wondered if it was attributed to the framerate .. what the eye perceives just not reconciling with the motion on the screen. Or maybe just poor game design.

theres been research on this perhaps have a search (+ please report any tasty links)

Well, flickering can cause headaches and that can be attributed to low refresh rates or interlaced video.
Motion sickness can come from motion that is percieved as jerky or not normal. (is too smooth a possibility as well?)

Please excuse me Vysez just want to say something on 30 -60fps debate. Ive been an avid lan party gamer for years. Even ran some parties at my place for quite sometime. Scooby at most intense lan matches you will see visual data reduced to increase speed. Even Quakecon participants do this. Speed in FPS deatmatch is a priority. FPS gaming at 30fps is a joke in my opinion.

Aren't there studies that show people are more sensitive to temporal changes (and thus motion sickness) than chroma? Most of my casual gamer friends won't play an fps that doesn't run at 60fps because the motion is so nauseating to them otherwise.

If that was the case every N64/ps1 fps would have came with a vomit bag. I don't think it's low framerates alone is what causes this. I think its nonconstant framerates that speed up and then down. I played many poor framerate games that never made me sick. But for some reason wolf3d, BUILD engine based games, and quake4 on the 360 will make me ill very quickly. Ken's Labrynth once pwned me something bad.

Of course they don't know what aliasing is, but they can SEE the difference between a smooth image and a jaggy image. Of course they can notice framerate drops, there is a minimum threshhold there, what I'm talking about is the difference between 30 and 60.

Of course, it all comes down to preference on forums like these, and everyone's opinion is valid. I still feel that fundamental improvements in the IQ are far more important than raising the framerate above 30fps, simply because it can be noticed by all rather than a select few.

I'm a hardware enthusiast and graphic whore, and the first time I played Quake 3 with and without AA on my 9800pro I could not tell the difference. If you showed my mother (shes only 40) the games side by side she wouldn't be able to describe the difference between the two modes. And I also know people who prefer no AA due to a "crispness" (AA introduces blurring at edges; not my opinion). So for instance, I would much rather have no AA + HDR in Oblivion and run @ 1680 than have AA + HDR and have to run at 1280*768 due to framerate issues. Or conversely, run both at 1680 and I would rather have no AA and keep a more stable framerate. I think the point is that it is often down to personal preference. I can tell you though that 90% of people playing computer games (consoles also) don't know the difference between AA and no AA, and if they do notice it don't care. Same goes for AF, though in my case no AF drives me nuts. And 60FPS feels MUCH nicer in an FPS like COD2 or Quake 4, but in slow paced games I couldnt care less (Oblivion is perfect @ 30fps down to about 26fps for me)

Well, technically, temporal change would be a change in framerate, not a low consistent framerate.
I also have friends who won't play n64 games because of the framerate problems, though I don't think the same applies to PSX, which I guess tended to have less framerate inconsistencies.

Oh, and wolf3d and BUILD engine games may make you sick because they mess with the aspect ratio of stuff since things scale as you move/change your viewpoint. Perhaps quake4 has some depth of field stuff going on, though it did have a bad framerate...
