So I have installed a R7 260x and it seems to be running slow, atm it looks like it will take about 60 hours to do a single large work unit, my 970 can do 3 units in about 20 hours.

Given the performance stats I would have expected it to do better:

260x = 1971.2 glops

970 = 3494 gflops

Anyone with a similar card able to let me know what they get? Do other factors affect the times?

I have edited the config file with the recommended optimisations, seemed to make no difference at all, which was the same result I got when I did the same thing on my 970 tbh.

I am writing this on my phone so cant put the link in. But have a look at the sticky at the top of the forum.

Also another thing I have noticed is that running more than one unit on my 970 makes little difference, rnning two units each one takes twice as long as running one, is this normal? I see a lot of people running more than one unit per card?

It depends on the project and the card, this project is very good at utilizing all of your gpu resources for a single unit, others not so much making running multiple units better.
