Editor extremely slow, making it completely unusable on my system #436

Closed christofferaakre closed 1 year ago

christofferaakre commented 1 year ago

OS: Arch Linux Window manager: awesomewm Fyrox version: 0.29

CPU: Intel i5-9300H (8) @ 2.400GHz GPU: NVIDIA GeForce GTX 1650 Mobile / Max-Q

I am trying to work through the 2D platformer tutorial (https://fyrox-book.github.io/fyrox/tutorials/platformer/part1.html).

The editor is very slow and unresponsive; I've attached a video. Sometimes, it is a little bit better (just kinda slow, not unbearable) for like a minute but it then it goes back to being unusable. I think maybe the drop down menus might be what trigger it. It seems like every time I open a drop down menu, the editor just freezes.

I didn't record the video with sound, but I am hovering my mouse over the nodes (even without clicking, this should highlight them with a dark colour), then also clicking on them, and the clicks aren't registered until like 10 seconds later. As you can see, when I open the "Create child" menu, everything just freezes and it becomes completely unresponsive.

Stupid question, but I have to ask - did you run the editor in Release mode? Besides that, the overall slowdown of context menus is a known bug, but I can't reproduce it stable enough to start searching for a potential fix.

christofferaakre commented 1 year ago

I ran it with cargo run --package editor --release as explained in the tutorial, so I think this runs the editor in release mode, right? And also, fair enough, if you can't reproduce it, I suppose it is almost impossible to troubleshoot it. No worries :)

Do you run the editor by using your NVIDIA GeForce GTX 1650? It could be like: DRI_PRIME=1 cargo run --package editor --release

@christofferaakre I was able to reproduce the bug using the steps found by @IceGuye and it should be fixed now. Could you please confirm that there's no performance degradation?

christofferaakre commented 1 year ago

@mrDIMAS I'm out right now but will test when I get home. Thanks!

christofferaakre commented 1 year ago

@mrDIMAS Yes, it is super smooth now. Thanks for fixing it so quiklcy!! Also, I didn't have to do anything? No update or anything? I don't quite understand how whatever fix you found was applied to my version of the editor, but somehow it was?

mrDIMAS commented 1 year ago

Right, I should mention that you should update first, since you're using stable 0.29. Please use this instruction to update to the latest engine version.

It's very weird that it all of a sudden is very smooth then, hmm.. Thanks for the link though!

Here's the steps-to-reproduce: create two scene nodes and select one after another for a minute or so (a bit easier than @IceGuye 's). If the bug is still there, you'll get serious performance degradation.
