I have similar issue. Main PC has a i9-9900k and a 2080ti, F12 renders a scene in 30 seconds with GPU/optix. When I use crowdrender with the additional 4 machines (i7 w/ no gpus) it takes longer than the main PC F12 render. Looks like crowdrender is not using GPU on the main PC. Is this how it is supposed to work?
Hi Psantana, one thing to check would be if you have CPU enabled with your GPUs, we've tested with others who have not realised CPU is enabled always, unless you actively disable it. Because of this, your GPU will experience a bottleneck when rendering since its communicating with your CPU.
We found that crowdrender got similar times using CUDA GPUs (not with Optix though, that support is coming) when the CPU was disabled from rendering, but much slower when the CPU was enabled in hybrid mode. In fact without the CPU, a test took 22 seconds, with the CPU it took 1 minute 20 ish seconds.
So please try disabling the CPU, this might give you a boost. Optix support is coming, but we're scrambling to get access to a CUDA/OPTIX card, we don't have one at the moment.
This is obviously not great, but can happen, the system attempts to balance the load on each computer by assessing how well the computers perform on previous frames. So I see two possibilities;
1. The load balancer doesn't have enough data to work with, usually on the first frame you render with a new project, this will be the case.
2. The scene is sparse, which makes it difficult to balance.
In either case, the load balancer can be essentially turned off and you can assign how much area of the image each computer gets. This can be done in the "Edit Load Balancing" menu where you could give both computers 0.5 each (so half the work) if you think both machines are about equal in the rendering power you think they have.
If you still have trouble, please write back, we'll do our best to help :)
Hi there, is this issue fix or Distributed render is still slower that one render pc?
Thanks

It wasn't much better with manual load balancing. Render time was 2:15 . Are you sure this addon works?
