Hi Stampeder,

your Caicos GPU is still a VLIW5 architecture, which is pretty weak at GPU sieving anyway. With just 2 compute cores, the expected performance would also be rather low. But the real...

Hi,

what exactly does this mean:


Did you leave it to Windows and it said the driver was up to date, or did you install the latest AMD driver yourself?

You mean the fact that mfakto processes lower bitlevels faster? That is because mfakto needs to use different kernels (different implementations) for different bitlevels. This is unchanged. All...

This is really cool. Did you replace the flag for all buffers? Is that all you had to change? I'm happy to roll that into the mfakto code.

The reason for the USE flag was simply that I took over...
