Is there any way to fix lag spikes?

[K-Bean]

My system specs are:
CPU: Intel Comet Lake i9 10900k 10 cores 20 threads at 5Ghz+
GPU: Asus TUF RTX 3080 8GB
Storage: 2x500GB NVMe Samsung EVO 970 Pro in RAID 0
RAM: Kingston HyperX Fury 2x8GB 3200Mhz
MB: Asus ROG Strix Z490-A Gaming

Even in designer mode while playing for an hour the game engine seems to start getting hiccups. A lag spike every 2-3 seconds that lasts meaby 30-50ms. (-hiccups)
After said time even deleting every design in the designer wont help.
The only way to fix this temporarily is restarting the game every hour.
Does anyone know a better work-around to this?

I'm guessing it's the game engine garbage collection, I've seen it other Unity games like Kerbal Space Program when you have a lot going on, a litle lag spike every few seconds.

I thought I read somewhere that a lot of RAM is good for this game.

Yes RAM is the key. 64 gig min i would recommend. If you play with friends. You all need the same amount. It does not matter who is hosting. If you and say 3 others have. 32 gig on one. 64 on another and 16 on the third. For the first 30 to 45 mins you will have no issue. Then Unity will "Garbage collect" Causing the 64 gig machine to demand 31 gig. This will cause a stutter for the 32 machine. and cause the 16 gig machine to fall out of sync.

The sync loss will get worse and worse for the 16 gig machine. While co building you really wont see any sync loss since vessel is probably suspended with caps. and everyones on there own section. If your close and are using the 16 gig machine you may see blocks just popping up randomly. and if You try and load a sub con. It will take forever.

Unity acts alot like a peer to peer conn for multiplayer games. It forces the same RAM req for all involved. As long as everyone has the same amounts problems shouldent pop up. If everyone is over 64 gigs This issue should never happen. Most ive seen the game pull since last under hood update is 51 gig.

Now for a single player experience. Think of each block as 100 bits of data. So look at your total on screen blocks you want to fight or build. Divide by 1000 for Gigs. This will tell you around what you need for the sim to go right. 50k ship needs 50 gigs to not drop into low graphics mode. or x5 10k block vessels ect ect.

This is in no way accurate.. Just my personal rule of thumb. I use systems that have 64 gig and 128 gig. This before mentioned tests come from my buds that have 16 and 32 gig systems. we play this alot together.
We all use win 10. Most of them use G force cards from 4 gig to 8 gig. I use Radeon cards. Cross fire 8's Sapphire editions.

This game requires alot of power to build huge vessels. But for vessels 20 - 30k you can get away with 8 gig as long as its 1 v 1. You will pop in and out of low quality but FPS should stay above 10. For Story and adventure i truly suggest 32 Gig. The rate enemies spawn in and story modes sheer map size with active elements. Slowdown is inevitable with low RAM.

Now DDR 3 works with this game just as well as DDR 4. So an older "2017+" Machine can be made to play this for cheap. 3 gig quad core. 32 gig DDR3 4 gig videocard "ANY" Put game on a 256 gig SSD. There you go. all you really need.
But for a more effective system. Digital Storm or NXT. They make kickass systems dirt cheap compared to custom build prices. around 2k American you can get a system that wont need an upgrade for about 5 years today.

Hope the txt wall helps.
