1) Message boards : Graphics cards (GPUs) : Very slow performance using GPU (Message 6541)
Posted 5553 days ago by Tom Shaffer
Upon my learning of CUDA,I replaced the 256MB ATI graphics card that came with my computer with a 512MB NVIDIA GeForce 9400 GT graphics card. The GeForce 9400 GT card works fine with seti@home and seti@home beta. However when I added GPUGRID to the the boinc projects that run on my computer, completion of GPUGRID projects proved to be inpossible. For this reson I am not taking any GPUGRID projects until the problem can be corrected.

Recently, it has come to my attentio that the GeForce 9400 GT has a low number of shader units and thus not listed in the overview of NVIDIA graphics cards. It appears that my experience confirms the observation of the person who made the posting. Any comment?
