4 months ago 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?

4 months ago 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).

3 months ago 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.

3 months ago 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.

2 months ago 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.

2 months ago @DerKameramann PrusaSlicer 2.7.4 is still avaliable for download. PrusaSlicer is Open Source, if you want to contribute a fix dont hesitate to do so.
its summer and vacation season, the devs have a life/family, please be patient.
no wonder OSS devs want to quit, suffer from bornout etc. when they have to deal with stuff like your comment. be patient and refrain from implying the devs dont care about this issue.

PrusaSlicer is Open Source, if you want to contribute a fix dont hesitate to do so. there is no need for another codenerd and I dont think you want me to teach how to fix such issues so dont call me up.
its summer and vacation season, the devs have a life/family, please be patient. well, a bunch of people, including me, are patient for 3 Months already i know they work on it - that´s why version 2.8.0 +1 is existent - but the problem persists and some say its parent is a major revision in the developer tool´s world dropping older hardware support. true? probably maybe. A statement like "nope, old hardware is not supported any longer" or forking a 2.7.x lts version dedicated to older hardware are possible moves.

1 month ago Same here. 2.8.1, with a fairly decent desktop computer. ryzen 5800x, 32 gigs of RAM, RTX3090. When trying to rotate the model in the preview view, it barely can keep up (2-3fps) with normal models, and it completely locks up with larger models. Looking at task manager, one core gets pinned at 100%
here's the model I was moving:
When viewing the whole model, attemting to move the "camera" results in a 30 seconds-1 minute lockup and then it moves. Viewing it like this (only first 15 layers) gets me an estimated 3fps.

1 month ago Same, the preview gets really slow. 80x80x80 cube with 15% grid infill. 0.2 layers has noticeable fps drop with just 50 layers displayed and after 100 its getting really bad...
Memory is steady around 400MB for this model and CPU shoots up to about 30% when moving the model.

1 month ago From this another problem arises: With PrusaSilcer 2.7 I can't access the new profiles for the new Prusa MK4S. Since I just did the upgrade I'm stuck with the MK4 profiles. This is definitely a thing that needs to be resolved somehow.

1 month ago New 2.8.1 made everything worse for me. A simpleformed 10x10x3 cm Skull-Objekt in the G-Codeprieview renders the App almost unresponding. I´ll give up, going back to 2.7, works like a charm.

1 month ago Same issue for me since 2.8.0 to 2.8.1 made everything worse for me. A simple formed calibration cube 20x20x20mm (https://www.printables.com/model/591501-calibration-calibration-cube) in the G-Code preview renders the App almost unresponding with 4 to 8 secs to refresh 3D after moving it with cursor...
What happened since 2.7.4 which works like a charm: I'm wonder to see OpenGL lost its graphic acceleration... ?
In waiting for next 2.8.2 version with optimized source code program, please add missing MK4S in 2.7.4 !!!

Description of the bug
The graphics performance of PrusaSlicer 2.8.0 seems to have largely declined on my machine. I'm using the internalt Intel UHD Graphics 770 of my Intel Core i5 Processor and that's usually 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. For large prints this is not even usable any more.
