LuxMark has now a dedicated web server (it is not like the old one), you have to register a new account: http://luxmark.info/user/register

It is mostly due to the kind if URL I used, this one should work even without being logged: http://www.luxmark.info/node/232

Very interesting and congratulations!

It looks a bit like the good results NVidia had for Luxmark 2.0 for Maxwell might have been partly due to benchmark-specific optimizations? If so, that's very disappointing.

I really wish NVidia would get its shit together and support OpenCL properly. I don't mind they try to tout CUDA by giving it say a 10-15% performance advantage, but 50-100% is pretty abysmal. Bang for the buck seems to be very low if you are using OpenCL+NVidia. Sadly, it still seems to me they are only interested in having "supports OpenCL" as a checkbox item.

So Nvidia is going to support FP16 and mixed FP16 _FP32_FP64 .

How do you think FP16 will impact luxcore perf.

But do you think that FP16 is enought for GPU rendering

FP32 is barely enough. FP16 has a 10bit mantissa (2^10 = only 1024 different values).
