Extremely low FPS when in Kerbin

[bigbackclock]

I'm getting from 10 FPS to 25 FPS when in kerbin, The only mods installed are KSC extended and its requirements with some part mods. It shouldn't be giving such low FPS on my PC as it can run all the games in my library at 60 FPS. My PC Specs are:
CPU: AMD Ryzen 5 1500 6 core
GPU: Asus rog strix rx 570 4gb
16 gb ram
Motherboard: Gigabyte DS3H

Hi.

A few things to try, are you running with the Ultra shader level selected? Have you tried lowering aero FX detail?

Also I'm curious whether FPS improves sharply as soon as you go above 10km altitude.

you should be running with the FPS limit at the refresh rate of your monitor... if its too high, it can really make a hit on your FPS, but if its just at Kerbin, then it may be graphics.
What i mean is that you should try to get the target FPS to be as close to or equal to the refresh rate.

I had the fps limit at max (about 120fps, refresh rate was 60), and it was choppy, that issue was fixed by setting the fps limit to 60.

Edit: alfer a quick google and comparing my Nvidia Gt 1030 vs your Asus rog strix rx 570, i found that your graphics card is significantly better, and my pc can handle pretty much max. graphics settings, and still be fine. (though i prefer just below max settings).... so idk the issue.... so i have no idea what is going on..... can you give us the fps when you are on other planets and moons? (try laythe, its similar... but idk)

My settings
I'll try putting FPS limit to 60 as mentioned by Jacob

You should try to match the FPS limit to you monitor's refresh rate, but try 60FPS at first

I did it, also lowering down all the settings to medium. Still no smoothness

Make sure you aren’t running the game using an integrated graphics card on the motherboard.

This should only really be affecting the game if certain parts are used but turn down your reflection resolution. 2048 is huge and mostly unnecessary.

I would also take a look at the log file. If something is spamming NRE's it can significantly impact performance.

How can I make sure im not using any integrated gpu?
edit:I checked the log file im not using any integrated gpu and nothing is spamming my log file. I'll try lowering graphics

Reducing the reflections worked fine, but I still feel the 30 fps. I don't think I can run visual mods, can I??

[Manwith Noname]

You can but you'll either need to tweak them and perhaps disable some features or deal with the performance hit like a lot of people do. When you see videos running super smooth with all the visual mods installed, they've more often than not "cheated". It's quite common for those video makers to speed up the play back so it looks like it was all running fine when in fact they were getting 10fps with major real time slow down (yellow or red clock).

If we take the main mods, Environmental Visual Enhancement and Scatterer, I find having either one installed is fine and only get issues when both are installed while flying in atmosphere. Things you can do to gain some performance:

1) Disable volumetric clouds.
2) Reduce the water shader settings or just disable the water shader entirely.

Also, if you use any visual overhauls that include Kopernicus, you may benefit from disabling the collision mesh on terrain scatter if they have enabled it. It might also be worth investigating their configs more thoroughly. I always loved KSPRC but in certain areas it would absolutely kill my performance. Eventually I found out why, under water it was generating thousands upon thousands of plants. Once I tweaked the spawn values a bit the biggest problems went away.

On the reflection setting, not sure what you have it set to but I did a bit of a test not so long ago and settled on 256 for general use. It's also worth noting that the size of the part doing the reflecting has a huge impact on how the resolution impacts the fidelity.

These are all quite old though, before Squad introduced their reflective shader and as a result their own reflection probe but this still applies...I think...I haven't done a specific test to check but from what I understand of how these tricks work, I don't see it being any different. Additionally, stock doesn't make anything big super reflective. The most reflective part is the rovemate probe core.

So if I play KSP with only EVE and Clouds mod with RealPlume and reflections mod I can get 45 FPS at least?

[Manwith Noname]

I would think so. I'd be a bit surprised if it didn't run at 60 to be honest, well, unless you are launching high part count craft, which is of course the other major impact on performance.

You can add and remove both E.V.E and Scatterer with no ill effect to your save so the best thing to do is just test what works best for you.
