Did I bought the wrong Videocard for Thea Render? (ASUS NVIDIA RTX 3090 OC)

Hi,
I'd like to have some advice.

My customer asked for an other PC for auto cad and sketchup rendering.

I advised an Intel i9 with a Nvidia Quadro RTX 4000 but the customer wanted a RTX 3090.

So we build and configured this pc for him.
Today they start using the PC and it does not meet the expectations.

The setup: ASUS motherboard, Intel i9, 32GB RAM, 512GB M2 SSD, ASUS Nvidia RTX 3090 OC.

The customer uses SketchUP and Thea Render.
The Benchmark score is 18152.

Also the GPU information in Task manager shows almost no activity during a render or during the benchmark.

What can we do increase performance? Or is this the performance you expect in this scenario?

 

Looking forward to your reply.

Thanks in Advance.

Rutger

    Based on similar GPUs, it seems that your client's GPU is performing pretty well. The following link filters out (3090 + GPU only) the results: https://www.thearender.com/benchmark/results3.php?search=3090&show=gpu

    Also the GPU information in Task manager shows almost no activity during a render or during the benchmark.

    Please open up the Thea Tool panel and switch to the Settings tab. From there, scroll down to the devices list and make sure that the 3090 is the only one enabled (ticked). If the GPU is not working you should be seeing a black screen in the Viewport.

    Kind regards,
    George

    another thing to check, that happens specially when a onboard video card is also present (i.e intel).

    Inside nVidia Control Panel there are a couple controls to define what GPU will be used in each application. Usually the options are standard and high performance.

    Make sure that Thea is set to use 'high performance' settings, so it picks your 3090 card.
