High GPU usage when color scheme is set to "Filament" or "Speed"

[Snelso91]

OrcaSlicer Version

1.9.0

OS version

Windows 10

Additional system information

CPU: AMD Ryzen 7 3700X RAM: 32GB GPU: Nvidia RTX 3060

Printer

Bambu Lab A1

How to reproduce

1. Slice a print
2. Change color scheme to "Filament" or "Speed"

Actual results

The GPU usage should be relatively low when viewing the sliced print with the default color scheme "Line Type" or any of the other schemes apart from filament or speed. However, when filament or speed is selected, the GPU usage increases from about 1% max to around 48% max when not interacting with OrcaSlicer. This occurs even when the window is not focussed and is not moused over/being interacted with, and also occurs when the window is minimised. The high usage does not occur if a tab other than "Preview" is selected, even if filament or speed remains selected on the preview tab.

Expected results

The GPU usage should remain at the same level as when using all the other color schemes. If this is not possible then the filament or speed color schemes should at least not have high GPU usage when OrcaSlicer is minimised or the window is not focussed.

I have been experiencing the same thing, although since I started using Orca (1.6.6). No issues whatsoever on all preview pages, except when viewing Speed and especially Flow, then it is a stuttering mess.

I have attached a video of how it looks. Recorded in 1080p 60fps

Can confirm the issue when "Speed" or "Filament" is selected. Doesn't seem to happen for me with "Flow". I see both increased CPU and GPU utilization even when Orca is idle and not focused.

I actually thought I had a crypto miner or some kind of other malware on my system when my 3D modelling software slowed down to a crawl and my 3090 was pegged to 100%.

What on Earth is orcaslicer doing that utilises 100% of a 3090??

Can confirm, I noticed that extreme GPU usage with both intel UHD 630 and GTX 1050. This is critical issue, because the entire system dies when this panel is opened. Oh, correction to the previous reports: GPU usage increases only when the color scheme panel opened, collapsing it "fixes" the issue. Demo: https://youtu.be/iL4akoPdn8I

Can confirm the same for a AMD Radeon RX 7900 XTX

Can confirm, same on Windows 10 w/ Nvidia GPU.

confirm upload up to 100% night beta v2 win10 nvidia rtx460

And if I click PREPARE the gpu load immediately goes down to zero.

Same. Macbook Air M1 on Ventura. 2.0.0 release. My laptop's (3rd party) temperature alarm was beeping at me even though I hadn't touched the machine for a few minutes. GPU pegged to 100% even when Orcaslicer is off-screen.

Orca bot: this issue is stale because it has been open for 90 days with no activity.

[NickUfer]

Push, still an issue

[Felix14-v2]

Can confirm in 2.1.1

[Snelso91]

I can confirm this is still an issue on the v2.1.1 official release.

This is particularly noticeable when slicing any multi colour or multi material prints, as the slicer always defaults to the "filament" colour scheme in this case, and so ends up causing high utilisation on the GPU and therefore causing unnecessary power usage as well as heat and noise.
