ahh, right Andy - thank you
KrvKpt. Falke I will change the settings as you suggest, check the GPU setting, though I would have thought Nvidia settings would have taken care of that automatically when I enabled SLI- but I will give it a go. I am almost certainly using the latest nvidia driver as I recently had to reformat, so I will see if I can get the older series and put that on. Thank you for your help. I shall have a go at it tomorrow.
