I've Win 10 x64 with GeForce 368.22WHQL driver (see my specs on bottom of my message).
I get 21.3 Mphotons/s on my GTX 980 Ti SC+@v376.66 driver but I get only 11% GPU usage because CPU is bottlenecked - i7-4790K@4.7GHz. :( ;)

mphotons/s seem to grow as time passes by, I don't know for what reason. The picture also looks kind of buggy (the first 2 spheres are black and pixelated, the sphere in the background and the cube is fine, caustics are fine also etc).
After 100 sec 76 mphotons/s, after 3 sec about 60. AMD r9 380 and AMD FX CPU.

In any case, this is really awesome. If such a thing was possible with Blender, it would be a breakthrough (the first GPU rendering with potentially great caustics and indoor results?). Then again, I don't know how this works, it may or may not be effective.

yeah. I would get ~240 Mphotons/s at full GPU usage. At SPPM, my GPU@real boost as 1315MHz core is ~25x faster than my CPU i7-4790K@stock with 4.2GHz HT enabled. ;)

i still can't get it to work
Fault module: nvoglv32.dll

Any ideas? How to troubleshoot?

Because maybe you haven't any NVIDIA GeForce videocard. Or you reinstall GeForce driver (GeForce card required).

But what prevents this full usage? My CPU is probably many times less powerful than yours.

Running GTX 980 Ti SC+@1315MHz core real boost and i7-4790K@4.7GHz:
- 11% GPU usage (1102MHz real boost) = 21 Mphotons/s
- 99-100% GPU usage (1315MHz real boost) = ~240 Mphoton/s (but I think this)

Can you understand well? :)

But @Dade (or other developer) hopes to reduce much or to remove CPU bottlencked for GPU to use SPPM... ;)

Sure, what confused me was that with a weaker GPU and CPU I seem to have gotten more mphotons/s if I understood properly. Of course that if your GPU was fully utilized, you could get better performance, but there might be something more at play here such as different GPU drivers (amd/nvidia), etc. Usually bottlenecking shouldn't mean that you get more performance out of a less powerful GPU (maybe in some case). Again, I might have misunderstood something, and I don't even know how this algorithm works (e.g. how CPU/GPU is used by the implementation).

Oh, sorry... forgot to mention: Quadro M5000 8GB (main) + GTX 1060 6GB (both use latest drivers), OS W7 sp1 x64 pro

You use DDU (look and download - here):
1. uninstall GFX driver with reboot PC required;
2. select safe mode in boot before run DDU;
3. clean GFX drivers using DDU with reboot
4. run normal mode, after reboot and install GFX driver. enjoy! ;)

Thank you.:) But I've knew that about few years...
