G-code preview performance is very bad with PrusaSlicer 2.8.0 and further

[the-powl]

Description of the bug

The graphics performance of PrusaSlicer 2.8.0 seems to have largely declined on my machine. I'm using the internal Intel UHD Graphics 770 of my Intel Core i5 Processor and that's usually more than sufficient. But with the newest version of PrusaSlicer when I want to rotate the view on a half decent model in the sliced Preview the framerate drops to below <1fps and the GPU load goes up to 100%. For large prints this is lliterally not even usable any more.

Version of PrusaSlicer

2.8.0
2.8.1
2.9.0

Operating system

Windows 10

Hi, please attach your system info to provide us with more data. It may help us.
If you export the G-code and then open it in a G-code viewer, is the issue observed as well?

Hello, same problem. After opening G-code in G-code viewer, the problem is also observed.

[foxylion]

The same for me. Previous versions where good to use. The 2.8.0 is unusable in G-Code preview (I can't rotate the screen anymore for big models).

Same here with Apple OSX Mojave on i7MBP17/2010

Very, very, very slow response in Previewmode and G-Code Viewer.

Same on my machine.
Although I don't see any performance drops in the slicer, I see it affecting other graphics-heavy applications when the slicer is in the background, doing nothing and showing a static picture.
Task manager shows the slicer running my GPU at 75% - and that's for an NVidia 4060.

same here, Model view is working without any issue even with models over 1M tris, gcode view is barely usable.

I reverted back to PrusaSlicer 2.7.4 because 2.8.0 is not usable at all for me.

[k1-801]

Over 90% GPU load when it is showing a static image. I hear fans on full blast.

UPD: Sometimes Edge WebView also adds random spikes of up to 30% (even though the physical printer tab is not even open), but I guess that's beyond our power to fix.

[ChiefPoints]

I'm seeing the exact same thing on MacOS Monterey, PrusaSlicer 2.8.0 is completely unusable when in the sliced gcode view, moving rotating the object, view layers and just clicking in the interface produces horrible lag. In addition to this here, I've relayed the same info in email to prusa. Version 2.7.4 was rock solid, no issues. Really need this working so I don't have to manually build profiles for the MK4S in version 2.7.4 - Here's the system info:

U will find lots of similar complaints since 2.8 is avable. It´s performance bug still pending and unresolved. 2.7 was rocksolid even on weak/old Hardware. 2.8 Preview is a pain in tha and it feels like dev´s dont work it out.
