@InqBit: is 137694 khash/s the first shown hash rate? Please run the miner 5 min and than look to the hash rate. The first hash rate is always lower because the first kernel call takes very long.
I see you run the code with without -aggression, please add -aggression=8 or 7 to you parameter to get more performance. -gputhreads is not needed because it is ignored and hard set to 256.

theoretic calculation rate for GTX480: 1401*15/(3733/32+1194/16)=109 MHash/s (magic numbers are the count of operations from the binary for this implementation)

Mhh in my theoretic calculation I assumed 109 MHash/s for a GTX480. I think I must check if my operation count for fermi is right.
Can someone with a GTX480 run the code under linux without -gpugrid.

I just made the appropriate changes and started a new run. Will let you know in a few how it works out.

FWIW, I've been running ~140-145'ish on cgminer, overclocked to 800 core (700 stock). This is my general use machine, so I didn't have aggression set to keep desktop usable, but will run at 7 for testing for you. I just checked my average hashrate on cgwatcher, and it is 140.1.

edit: 10 minutes later

C:\miners\rpcminer nvopt>rpcminer-mod-cuda.exe -url=api.bitcoin.cz:8332 -user=user -password=pass -gpugrid=512 -gpu=0 -aggression=7

last 5 hashrates
140345 khash/s
140360 khash/s
140052 khash/s
139525 khash/s
140080 khash/s

What hashrate where you getting without cuda?
