Render performance degrades over time

[nikowo]

Note up front: This is me playing the game on Linux via Proton (I also tested generic wine, through Lutris, which changed nothing). The older itch demo did not have this problem.

So basically, the framerate jitters constantly between ~140 and ~70 when the game opens, then slowly both values slide down to the point where the game is running between 4 and 50 fps for reasons I cannot fathom. Is this a memory leak? Only on the GPU? Only on Linux?? I should look at my system monitor while I'm playing next time but good lord it actually becomes unplayable at its worst, since it stops receiving inputs.

Disable vsync and give it a go

[nikowo]

Oh it's already off!

[PugKonfuzio]

Dang, then IDK

Several people have reported that issue, even those with RTX9001 and such
Some have fixed it by disabling the vsync 60fps option (myself included), other just can't figure it out

My setup:

Linux mint 22 cinnamon
Steam proton experimental/nightly
HP laptop sporting a Ryzen 5 3500u
8GB ram single stick

I got the same problem:

Windows 11
Ryzen 5600x
Nvidia 3080
32 GB of ram

Are you hosting lobbies? I've heard hosts always suffer from degrading performance.

My guess is player records aren't cleared from memory when they leave the lobby.

Lenovo laptop
Win 10
Intel I-7 6700HQ 2.6GHz
Nvidia 960M (4G-vRam)
32G Ram DDR4 (upgraded from its original 4G
2T M.2 NVME (also upgraded)

I so far have not had any issues.

Oh, I'm running it on Ubuntu 24.10 with GE-Proton 9.20
Not hosting lobbies because I expect that to be worse, playing solo until it's resolved

Running a uhh...

I do experience fluctuating framerates, too. It stays 72+ most of the time. There's a few instances where I see it dip, most notably when accessing my storage. I almost always keep vsync on so I don't notice the fluctuations, causing my FPS to flip-flop between 144 and 72.

I have not experienced a time-based degradation of framerate.

Kiseff is optimizing some stuff related to players and storage next update, so it might alleviate your issues. ETA is Soon (TM); was aiming for by this weekend, but testing is taking longer than expected.

Booted the game up again and the performance suddenly tanked while fighting some Brightwoods, not the first of them I had encountered but evidently they just made it go bad.
After respawning form losing the fight as a result, I note that the framerate has decided to be ~15 while the game is processing any inputs (movement, camera mouse, attack, spells, even navigating menus). While not receiving inputs, the game runs ~120, where before the incident it was running a very very wobbly ~180? Like it was jumping between 70 and 180 but felt normal.

Do you have more than one screen hooked up?

[nikowo]

I do! They do not match refresh rates either, for what it's worth.
One is 2560x1440 @ 144Hz, the other is 1920x1080 @ 74.97Hz
Second one is rotated to Portrait Right, if it matters.
I have not played the game with my tablet attached, but assuming it is retained in X11/Wayland's memory for config reasons, that is a third running 1920x1080 @ 60Hz.

I personally run a 144Hz TN and a 60Hz IPS monitor, with Atlyss running on the 144Hz.

I was about to suggest it could be the Proton version (I know Lunacid had some rendering troubles on the latest stable at the time, 8.0 iirc, but not on experimental), but it might be the AMD CPU. Why would a Unity game run poorly on an AMD CPU? No idea! But all the reports of issues in here share a Ryzen CPU.

Try having only one display plugged in, restart windows and give it a go

[nikowo]

>Windows.
But I could try it sometime
