[2.0.73] Extreme intermittent lag on Vulcanus (CIRCUMSTANTIAL/SOLVED)

Post by nathan67003 »

1. More or less just arrived on Vulcanus via my first ship.
2. Ever since I podded down, I experience INTENSE lag when not completely zoomed out, but not constantly. Can't for sure say I've found a correlation somewhere.
3. Game keeps playing as usual. I hadn't had any performance issues up until then (since Metal support happened, OpenGL issues were very similar - had extreme lag during certain main menu scenes, chiefly Gleba ones).
4. It's systematic. Alleviates when completely zoomed out.

Not quite sure why I wouldn't be able to run the game at max settings, honestly; the CPU and GPU should be fairly able to support it, afaik.

Some specs: running macOS 10.14.6, CPU: 3.6 GHz Intel Core i9, GPU: Radeon Pro Vega 48 8 GB


EDIT: Seems like kernel_task was busy with ??? when I made this and the screenshots. It's not now and game's fine now. My bad.

Screenshot outside of a lag episode. Noteworthy that lag (FPS) hit like a truck (decreased to ~24 in under 10 seconds) when I zoomed in close.

Config, in case the fact I'm running windowed fullscreen at 5K (or something else) matters.

It seems the system as a whole is struggling in that instance, it is not one thing that suddenly takes longer, everything does. I'd start by checking temperatures and updating drivers.

It's a mac, you don't, uh, update drivers, really. Temperatures are Normal for a demanding game (mostly 30s-50s, GPU diode high 70s or thereabouts) on an iMac, afaik.

...Never mind, ig. I'm on Vulcanus atm and everything's working fine.

I noticed that when I posted this thread, kernel_task was intensely busy; now it's back to 1-3% instead of 150+...

Circumstantial bullscheißery, ig. My bad. Changing the thread title to reflect this.
