never mind, i found the problem, it seems version 6.3 and 7.2 are not compatible. they treat the generation different no matter what option you choose, the moment i update to 7.1 the result was the same as on the farm so i have to redo all the hair.

Side question, why 7,2 is so slow in viewport, 6.3 was so much faster and the display of strands is so thick on Guides From Surface i have to Apply Hair from guides to make it works better even with display lines as viewport option?

Thanks for the replies, i've managed to quickly redo the hair, this gave a better result overall so i'm not mad at all. But the only thing that stands out and quite a drawback is the time it takes to rememeber the roots compared to V6. Its like -2-3 times longer, i was waiting 2-3 mins on v6 now it takes as long as 7-8 mins.

The performance drop was caused by the guides width setting it came at 4 by default instead of 1 , after that change on edit guides the viewport behaved better, but not as fast as v6.
