PSS: what the fucking fucking fucking fucking fucking x 10 ^99 fuck is FrameSkipping?
Normally when you play games on your PC/handhelds/consoles, the animation in games that you see is basically a series of still images being moved at high speed and you feel like the 'things' on the screen are moving... the same is true for ur TV.
now normally in a movie (there are ~24/25 frames (images) played at highspeed per second)....
in a normal PAL game, there are 50 frames/second being shown on the screen.
in a normal NTSC (or a normal pc game) you hve 60 frames (images) shown in one second.
and there's those 30 frames/second category too, that you've been arguing on on that PS3 30 FPS games thread of urs.
now Frameskipping is .. like skipping some of those images.. so if ur PC for exmaple is playing a game slow .. like half the real speed .. i.e. 30 frames/sec of the original 60 frames/sec ...and u r annoyed that everything moves in slow motion ...
this technique can makes things faster ..although not upto the guranteed 60 fps ..but u do gain some speed...
whats done in this technique is that like in a generic frameskipping ... every 2nd frame .(or every 2nd image of those 60 images/60) are skipped
and whats outputted to ur screen in one second are 1,3,5,7,......,57,59.
so ur hardware needs to process only half of the workload..
but as a good side affect .. if u are already able to play at 60 fps and u still use frame skipping ... u can actually get generic 2x the speed ... so thats what FS is used for.
also ... there's no limit on how many frames u can skip ...
i.e. u can have an output of something like 1,11,21,31,41,51 if u skip 9 frames out of every 10 frames...
anyway... hope this helps somehow.
