i was shooting yesterday and it was gusty but not a steady gust...it would blow and quit quickly...at full draw i noticed the wind blew my whole bow lol. it wasnt a constant gust...i didnt see any effects on my arrows. though no doubt it can and will drift your arrows. it will drift rifle bullets that are relatively tiny compared to an arrow and moving at ~3000fps...so a big ole arrow moving at 250-300fps is going to be effected...

one good thing...i dont REALLY have to worry about it when hunting....if its windy enough to worry about arrow drift, its too windy for me to be in a tree!! i cant stand sitting in a tree when its blowing sideways...i have nightmares about the tree im in blowing over and busting with my extra weight up there...wierd lol
