At stock 500mhz, a 240p video is about 10fps. 360p is still a god awful slide show. I went to overclock to 800 which had previously never been a problem for me and it locked right up. I'm thinking that's the new NEON code they've got going, much more finicky about overclocking. Trying again...
Ok, no problems this time. Full screen works, nice and smooth at 240p; I suspect this is the new big feature, going fullscreen is great! Let the video buffer completely before playing, looks like the act of buffering chews up some precious CPU speed, works a little better once it's done.
Was about to test some newgrounds, but gotta go. I'll be back tomorrow to do that.
