OTOY Forums

Hi

I decided to try Octane but it is so slow in viewport, there is so much lag, that i am unable to work, it happens on simple scenes also (1 light setup), here are my pc specs:

Procesor Intel i7 3930K
GeForce with CUDA GTX 670 Gigabyte 2GB
Corsair DDR3 2x 8GB 1600MHz CL10 Vengeance LP ----- 2 pieces of this KIT making 32 GB total

mobo - Asus sabertooth x79
SSD drive
a 700W PSU

Windows 7 64bit

All latest drivers installed

Can this be a RAM problem? i have this issue with my PC that after i turn off the PSU and turn the PSU on again, i cant turn the PC on, i have to reset BIOS to be able to turn PC on.


Octane is awesome and if it will work like in my friend's workplace (who by the way has slower PC and graphics card than i have at home) i will surely buy it.

Hi, Most likely this will be because you only have the one graphics card and it is being "maxed out" by the rendering so there is not much power left for the display. (Hence UI lag).

The best solution is to get a second card to use for display only (plug your monitor into this one).
It can be simple/cheap if your not dealing with huge scenes in 3ds max.

The other option is to try the priority feature. If you are using the 3ds max plugin demo you are out of luck, the demo is an older build that does not have this feature. For the standalone look here: http://render.otoy.com/manuals/Standalone/?page_id=176 Tick the card to use the priority, then on the main viewport there is a button to select the priority to use (high, medium or low). Try medium or low. It should ease up on the GPU usage so that there is more "room" for general UI stuff.

Thanks

Too bad the 3dmax demo plugin does not have this priority feature, its impossible to get an opinion on the software with so much lag. At my friend's workplace everything was running smoothly, so i guess its becouse he has the full version. But he only has one graphics card, and as i wrote before, its worse than mine, mine is lagging on scenes with 1 light and one simple object.

The standalone version is running smoothly whether i have the priority option turned on or not in prefferences. I guess its becouse only the rendering viewport is displayed.

In bathroom sample scene, when looking from "bathroom camera" the "render target PT" doesnt refresh at all, it hangs, PMC is very slow and laggy and DL renders ok, i though i have a decent graphics card, is this normal? In octane benchmark all render targets refresh with PT refreshing the longest, is this normal behavior for my graphics card? maybe it is faulty.

What graphics card would you reccomend as a second card for handling semi complicated scenes? (not more than 10 lights and 50/100 objects) That would go well with my PC setup?

PS: how is the 3dmax plugin development going? and how does it compare to the other live plugins (mostly Cinema 4D)? Which software has the most potential with Octane right now and in couple months time?

Are you experiencing UI lag - ie: clicking on things in 3ds max is slow and un-responsive, or are you talking about the time taken for the image to become noise free? DL will always give you the most interactive rates, PT and PMC are designed more for high quality renders.

The 3ds max plugin is very mature - it was the first fully integrated plugin. It is still being updated along side each standalone release with the new features the core engine provides.

I really don't know what card you would be happy with for your UI. Some people have onboard video cards that work ok for them, others might want a quadro for display. It really depends on your budget and expectations.

The UI and navigating the viewport lags, the octane window lags when i move it around, the rendering inside the octane window is fast.

Ok, it turns out the low priority checkbox helps a lot.

Also, when the ocatne render viewport window is small i noticed there is a lot less lag.


Having that in mind, do you think that buying another graphics card will make the 3dmax and octane viewports run smoothly, and the other, stronger card will get busy getting rid of the noise?


PS: So far i am amazed how fast and accurate Octane is, do you plan to implement hidden geometry visible in reflections option (for plane shape reflections), lights affecting only reflection/diffuse without being visible in render? is it possible in octane and eventually be available?

Having another card for display only will make the UI run as normal (as if your were not rendering). The other card that is used purely for octane can render way and deliver results without effecting UI speed. This is the main advantage. The other advantage is quite often windows/3ds max consumes VRAM of the card your monitor is connected to (for display). Meaning that if you don't have a dedicated display, your scene size is smaller, because of this VRAM usage.

I'm hesitant to comment on our roadmap but we have definitely heard many requests for object visibility and we keen to see this happen in octane. I can't give you a timeframe or any promises sorry.

Thanks
Chris.
