LOL !
I've got more than a reason to think that this is a scam, the first is that the GPU code is not inside the miner program but inside the .cl file, so I don't think you could be able to optimize anything only with the miner, but why don't give you a chance?
I've tried to download the linux version without luck, would you reupload it please?
Also email will be fine jeky (at) [Suspicious link removed]
EDIT:
I've read all the thread and discovered that probably the modified miner also includes a different .cl file.
So probably the author could be considered UNFAIR but not a scammer !
If someone want to send me the linux version I would be happy to test it. Thanks
EDIT2:
Sorry for what it was considered a "suspicious link", I only wanted to use an email different from my master email!
Probably this one is better: jeky (at) community.it
Sorry again
