alright, so for some reason, on my server (i haven't experienced this on my friend's 90k brick server) when i load a somewhat large amount of bricks, it seems i alternate between perfect fps and as if i were looking at hundreds of thousands of bricks at once.
i thought maybe it was shaders doing this, (all of them are available to me, but only minimum does anything for some reason, probably intel) but even with them off, it still does this. it only does this on my server, as far as i can tell, and when the bricks are loaded. after they are cleared, it no longer happens.
my specs -
windows 8, 64 bit
intel core i3-3227u @ 1.90 ghz dual core
intel hd 4000 integrated graphics card
4gb ram
to be honest, blockland sometimes makes my laptop hotter than skyrim.
