Re: Cycle X (and OpenCL)

as you seeit's even worst...2X power absorption for 1.5x-1.7x performance boost. Octane bench shows score of 130 for gtx1080 vs 655 for 3090... It's one thing that 3090 alone is a special terrible case of crazy power consumption, but to claim 6x for 6x performance, or even 1.5 performance boost is ...

Re: Cycle X (and OpenCL)

"lacilaci" Hi, I'm here reffering to your post of page 4. I think Nvidia almost did not delivered any performance x Watt improvement during the past 6 years. A new Nvidia card, if it is 4 times faster as an old one, it consumes 4 times more power. Not the same we can say about the CPU industry wher...

Re: Faster Compiling kernels

Direct X 12 (which has existed for a while, but only works on Windows 10) = Vulkan = Metal. All Low Level graphics Apis, with compute shaders. Why don't people use these technologies if they are as good? UE4 already has a full blown pathtracer that runs on dx12, I think it's also made by the guy th...

Re: Faster Compiling kernels

If everyone had/wanted Nvidia cards then Opencl is pointless Everyone who is doing CG professionally is already using an nvidia card. AMD only seem to care about competing with gaming side of things, providing cheaper gaming hw. Apple on other hand with their metal might be a proper alternative for...

Re: Product rendering issues

here I chose more extreme color to better illustrate that even if I set BG visibility to specular only I still see red bg affecting diffuse and gloss

Now that I think of it, If I could turn everything except case into holdout it could help a bit too, which is yet another issue :D

Re: Faster Compiling kernels

LuxCore "v3.0" will require no compilation at runtime, not even the first time. If you provide pre-compiled kernels can't this lead to errors due to specific driver issues etc? I often think that octane has sometimes bugs with memory leaks and freezing due to pre-compiled kernels but I don't know i...

Re: Cycle X (and OpenCL)

LuxCore API already supports it (more or less): you see it in action when you enable viewport rendering and edit the scene. It is up to BlendLuxCore to redo the same when rendering multiple frames. It has been discussed in the past, it is doable but it is not a small amount of work. I see, maybe cu...

Re: Cycle X (and OpenCL)

In other news about recent cycles development... persistent data! Luxcore has become crazy fast, however it all goes away if preloading scene each frame takes several times longer than rendering the frame... Being able to just selectively reload parts of scene would be an insane speedup for animatio...

Re: emission ruins photon cache

It looks like you used very small backplate. Mine is much bigger than the whole scene (this is sometimes necessary for proper paralax camera movement and reflections, and of course if your scene is big) Yes you are right i made bckplate 10X bigger and it kill all. Another idea is just to compute ca...
