FPS drop after some cycles

[afonsolage]

Hello folks!

I'm wondering if it is just me or the FPS counter starts to drop fast. After a few seconds the mobs movement isn't smooth anymore. Also, you barely can move the camera, because of this lagging.

Also some glitch like this happens when you move the camera on a low fps:

I'm using Ubuntu 18.04, on i7, 16 GB and GT 720. Don't know if this is a linux only behaviour.

This is strange for me, because the ECS style should distribute the work even if you have a high number of entities, but on this case, with just a few hundred the system starts to get high load. This is the Evoli implementation itself that needs to be improved or is the amethyst ECS that isn't production ready yet?

Thanks!

I've also experienced this locally (mac osx) and am interested in learning what others think is the root cause.

Is this perhaps related to this amethyst issue? Haven't heard of the same happening on Linux, though.

[waynethewizard]

huh probably is in my case since I'm using metal and have very similar experiences to what's described

I just re-compiled and with cargo run --release the performance is much improved. Maybe something to do with the latest amethyst release?

In my experience it is difficult to reliably replicate the bug. It may still occur at some point, but it'd be wonderful if it was fixed :D

I have fps drop and glicthes with models of bees on fedora 31 with intel hd 630.
