Hm. The new update (1.2.2.1) seems not to work for me:

I wrote a function that shows the "jump" from the position that was send and the position I "predicted". The red line shows the jump. Using 1.2.2.1 it looks like this:

but with anet version 1.2.1.1 it looked like this:

as you can see, it seems to update only once a second now with the new version, which is not enough for what I need. Also, the bullets that I create using enet_ent_create only get fired about once a second, even though I set the "reloading time" to half a second...
