hello all

i just downloaded demo version and successfully got a node inside
it starts rendering but at the render viewport at the bottom right corner, where the meter for my GPU is shown it says 41.2/1023MB used and as a result its really slow to render
what the problem with that? what should i do?
thanks

the memory usage gives no hint about if the rendering is fast or slow. it just says, that there are 1023mb vram available with your gpu, and that 41.2 megabytes are used. but in the same line, on the left, octane tells you the current performace, stating n.nn ms/sec (megasamples per second). what did you try to render, how are your settings, and what hardware do you use?

EDIT: sorry, overseen the thread title; you use a laptop with a 280m. depending on your scene, you should expect something in the range of 0.2-0.6 ms/sec - what is of course slow compared to a desktop card (around 2-6 times faster, depending on the model)...
The obvious is that which is never seen until someone expresses it simply

I am using an i7 Q720 1,60GZ
NVIDIA 280M
8GB of ram
windows 7 64bit and
trying to render a scene from XSI (old version, 3 smthing i think)
at the bottom left there is a progress bar? ascending from 0/16000s/px and goes on till the end with 5,4-17,6Ms/sec and 9-30fps
is this still ok?

5,4-17,6Ms/sec is a good speed for a laptop GPU. The progress bar counts by default up to 16000 samples per pixel. This value can be set in the kernel node. Depending on the scene you may need much less or more to achieve acceptable image quality. You can look at the rendered image and see how the noise clears up while it is rendering.

sounds ok to me, but hard to compare without knowing how your scene looks like. having speeds like that, you apparently use the direct lighting kernel, which is the fastest (but biased) - or a dead simple scene. btw, fps isn't really a measure, as octane is still a raytracer, not a realtime gaming engine ;)
