At 30fps@120Hz you should have gotten 4 trailing images as your eyes tracked things.
Not really blur, but a sharp alphablended sum of spaced ghosting pictures
You could call it blur if you move slowly and they are spaced just from 1 pixel.
Well wait I did't say it was the case, I just said it was possible :) I think some developers attain less lag so I'm just thinking of what could do a difference. More testing would be needed. You test the lag between mouse cursor and application by filming the screen at 60Hz and count the 60Hz frame...
By the way I think it's fair to mention some people were already using the led + video (60Hz it seems) method to test frame lag in 2009 on consoles, there even were modded led controller devices. http://www.eurogamer.net/articles/digit ... or-article
I really believe it would be very good too, to be able to test input lag for mouse move. Although not very likely, there might be a difference compared to fire, be it in the mouse hardware or firmware or in the game engine (and what if game engine does not fire first frame etc) I know it is far less...
hate to crush dreams :) but numlock and such are actually commanded by your main processor, this was already the case on a 8086! I was shocked too when I learnt that a long time ago! So there would be some uncertainity about the time of the roundtrip, potentially not negligible. If the keyboard has ...
1000fps @ 1000Hz has only 1ms persistence, without needing to strobe. Yes obviously there's a point where things are basically solved but if we cant generate that much fps, hiddend sample and hold + strobing is superior to crt/oled scanning if it's as wide as the frame time. 1000fps @ 1000Hz has on...
wow, I realize, which is to say, sample and hold (speaking of lcd alone, not constant backlight) is actually good, since strobing saves us from the effects we just discussed, and strobing is the only thing that can save us (scanning oleds and crts are screwed because of the instantaneous forgetting ...
Just realized that randomized or algorithmic pattern order of the update of pixels in one frame (for multiplexed oled for example, crt is not doable and lcd-tft do not blink individually) (also suggested by Carmack if I remember) would unfortunately be very bad for this reason : it would randomly di...
Curtain is by analogy to the curtain that fall in theaters at the end of a play btw, but it seems not to translate. Anyway even without having to explain these subtle effects, the mere fact the updates descend top down is intuitively not natural, the moving update line is maybe consciously or uncons...
Yes, it's funny we need to further isolate the discretized "universe frames" even further, while real life is continuous, but that's because the frames stand for infinitely small moments, and the inbetween values we get are false, so best is to just send nothing rather than wrong; the mind will have...
