Suggestions / More realistic and uncapped combat speeds
« on: March 01, 2021, 04:18:03 PM »
Hey guys,

So I was thinking about ship speed limits and how it doesn't really make sense in space. I also feel like it makes most ships, even destroyer-sized ones feel very slow. It's especially annoying when trying to get to the other size of the battlefield or trying to chase down remaining ships.
Furthermore, it feels weird when your ship loses speed after maneuvering jets or burn drive expire.

My idea was to remove the speed cap to make combat more dynamic (don't get me wrong it's already a blast ^^) and more realistic, but making going over the previous ship speed cap either generating flux (the faster you go, the more energy you need to accelerate) or having diminishing returns on acceleration to keep it balanced and to prevent ships flying around at crazy speeds. Additionnal speed due to burn drive, maneuvering jets and co should probably be kept as long as you don't accelerate in another direction.

Ship with garbage acceleration/maneuvering will still feel sluggish to fly, but at least they would go faster than 10 km/h  :D

I'm not sure how much work that would represent, how hard it would be to balance or if it is even feasible or fun at all, I just thought it was an interesting idea to discuss. Maybe I just watched The Expanse too much lately ^^

Bug Reports & Support (modded) / Performance Issue - CPU Bottleneck ?
« on: June 09, 2020, 01:28:58 PM »
Hey guys !

After playing with mods for a bit, I noticed I had significant performance issues during combat, especially during big battles. I've used The Last Hurrah as a baseline for my tests. With mods, I often had around 30-40 FPS during this mission with 0% idle, even without much stuff going on on the screen.

I've tried disabling all the mods and then playing on a clean install, no mods. I gained a few FPS (it sits at ~40-60 for most of the fight) but it's still very low compared to what I am expecting (targeting 144 FPS).

After a bit of digging and CPU/GPU usage monitoring with MSI Afterburner, I found out that my GPU sits at ~20% usage at most and 3 of my CPU cores are often at nearly 100% load, which seems weird to me since Starsector is supposed to mostly use a single core. RAM usage seems to be fine.

FIY, on the campaign map with Nex + 5 faction mods + adjusted sector (x1.1 sector size) and a bunch of other mods, I hover around 100-120 FPS with 0% idle, which is more understandable as a lot of stuff is going on. Without any mods, I get a stable 144 FPS with 30-50% idle.

These are my specs:
- i5-2500k OC'd to 4.3 GHz
- MSI 970 GTX OC'd (4 GB VRAM, 1113 MHz core clock, 3953 MHz memory clock)
- 16 GB RAM
- Windows 10 64 bits

My settings:
- vmparams RAM set to 8192.
- vsync off
- fps 144
- fullscreen

The steps I've taken to solve the problem:
- Making sure the GPU was handling the game through the Nvidia control panel
- Disabling Vsync, setting the openGL stuff on the 970 GTX in the control panel
- Updating the drivers
- Reinstalling the game

I haven't found any solution so far as most performance issues with decent rigs seem to be linked to AMD GPUs, which isn't my case.
Any help would be greatly appreciated, let me know if I can provide more information, or if I can get more precise tools to monitor how the game uses resources.
Thanks a lot !
