build videocore driver: Video :)

Wed May 14, 2014 1:32 pm

So i was planning bto build the broadcom videocore driver (remember simon?) So the instructions say to over clock to 900mhz but i plan to do at 700mhz, no overclock whatsoever, what are my chances ?? How much time do you think it will take??

Chances are exactly the same as with the 900 overclock! Just 30% faster,

Personally if using this I'd underclock, to say 500 MHz as you don't want to compile too fast, do you?!

That's not an error, don't worry. Also in the instructions I say how to record the frame rate. The type of SD card in use really affects the frame rate. If you can play the demo and it makes it all the way to the end in about two minutes, this is success :D
You can read more about it here: http://www.raspberrypi.org/forums/viewt ... 63&t=73932
eg see the "Why is the speed generally slower than the VPU version" and the "Why does the speed degrade with time" sections.

Yes got it under 1 min 18 sec @700mhz
But how (or even can ) you get the 100+ fps as shown in the blog post http://www.raspberrypi.org/quake-iii-bo ... -a-winner/

That picture has nothing to do with the open source driver. It is even older than the competition itself.
