GPU_ECM seems to not use GPU
I managed to find and download an apparently gpu enabled version, found the missing nvivia dll and tried it out with a prime95 stage 1 curve.
Result? - it did ALL of the calculation on the cpu, didn't touch either gtx card once, even specifiying -gpudevice 0 made no difference at all...and it's about 25% slower than gmp-ecm v7...oh well
