gtx 780 works slow

hello,
i just bought nvidia 780 3gb and rendering with CUDA seems slow.
i tried benchmark test and it works like gtx 275… what could be wrong?
thanks

Hi, try my benchmark, there are GTX 780 in the spreadsheet (Page 8).

The BMW benchmark has very bad tile setting for GPU change it to 256x256 for example.

Cheers, mib.

Do what mib says. By default cycles is set to 64x64 I think. Also make sure it is enabled under the render settings and in the user preferences. I’m sure it is settings issue. No one can switch from cpu rendering to gpu rendering and be disappointed.

mib: I tried that benchmark and it was rendered in 57.83, so compare to other card it seems good :slight_smile:
thanks
