cbuchner1: It works fine with my nvidia card - 50Kh/s

But
WHY IT DOESN'T MINE SHARES on pool?

Console window shows "accepted" messages but my pool shows that your miner doesn't mine any shares(worker has 0 kh/s, while cpuminer's worker has 10kh/s)
When you planning to release real working(shares mining) version of cudaminer?
