Just make things faster ...
Cheat engine ==> Settings ==> Scan settings, just add the "fast scan by defauld"
Then use the lame way to hack speed or a better i will explain
your attack speed is 124% ?
make a FLOAT search (rounded by default), and type 1.24 then unequip tour weapon your speed is (for the example) 102% so search for 1.02 ==> with that methot the value will popup really faster
And now add it TWICE
on the second one you added, just for the adress do -4 (7EFB4654 will be 7EFB4650)
==> C becomes 8, 8 becomes 4, 4 becomes 0
Well done now the first adress is Attack speed and the second is Speed

Now freeze it and put 10 to speed (never more than 10 or your char freeze)
and for attack speed, only archer with a bow can fully use it ==> make it 50 (when the game lag) or just 500 (when theres no lag) it wont shoot at that speed exactly but you use the full potential of the speed hack
edit : the adress change everyy time you DIE/mount, unmount a horse/change map/change char/...
with that method of scanning + fast scan ==> really fast way to activate it (less than 20 seconds)
And one more thing, even with fast scan, after an hour or 2 of gameplay; IF you switched maps a lot, the game will be bigger into your RAM ==> search even with fast will take a longer time so i would advise you to exit the game fullyy eand re-launch metin2.exe
Hopes it will help you
Just for an info, the FRENCH server isn't protected at all... some of the top 10 users are hackers and never got banned (tekisama for example) so have fun
