I have Lightwave 15.3 on Windows 10 with GeForce GTX 650. When I try to render with Octane it takes about 4 minutes per frame. With LightWave's own render it takes less than second per frame on same settings. Addition to this Octane render looks terrible. I am using LightWave's surfaces with texture maps on model. Does this cause Octane to be so slow or is there something else? With other model Octane just skipped textures and used objects color. I gave Octane try because LightWave's own rendered felt too slow. I'd like to do same scene with Octane but much faster. I have understood I should use Octane materials. Is that only reason for slowness?
Edit. Same problem with simple object without textures. Still 4 minutes per frame. Is this really this slow?
Octane Render for Lightwave extremely slow

Octane has it's own render settings, not related to the LightWave render settings. Probably you are not configuring the render target nodes, specially the kernel node samples parameter. The default samples parameter is too high.
Also I am afraid that your GTX 650 is not specially fast for Octane, with only 384 CUDA cores. Be aware that currently the fast GPUs have at least 2000 CUDA cores.

Take a look to the plugin docs to know more about the render target, the kernel settings, etc:

Thanks. That made it much faster. Now problem is my GPU. If I am going to invest in new GPU how should I value the score in https://render.otoy.com/octanebench/results.php? If my current GPU has 10 is one with 100 ten times faster?
Yes, you should think about get at least a GTX 970 or 980/980ti GPU, if possible.kvesti wrote:Thanks. That made it much faster. Now problem is my GPU.
