Hello prospectors,

first of all i love the game! 550h of playtime and i still enjoy playing but after completed all the missions for Olympus and New frontier i wanted to keep playing in open world.
The problem is i cannot run the game smoothly on my config.
I tried different settings but it seems to always perform badly in open world as opposed to during missions. I had almost no performance issues during mission but as soon as i started the game in open world i had lags right from the start, without even touching voxels nor placing deployables/constructs.
Here's my config, setting and a video of how the game runs.
I also tried to run the game on a SteamCMD server but instead of low fps we experienced lags.
Any ideas?
Thanks!

We have the same problem in Co-op (on Server Dedicated), at the beginning of the session it works well but over time it becomes unplayable, please help us

Wow 🙂 your game is even more or less smooth than mine.

You are experiencing what all prospectors with large prospects are experiencing. Few second of smooth gameplay with sudden FPS drops and stutters. Devs are unable to fix this. They are trying step by step optimize the game as much as possible but also confirmed problem is in the coding and cant be fixed without re-coding the game completely.

ok, thanks for your replies. The thing is i did not notice such stuttering in mission mode, with the same (roughly) constructs size. Pets and mounts seems to make the game a lot more laggy also. When i ran the server with steamCMD i noticed a lot of errors coming from pets and mounts (rigs, rotation of skeletons and so on) I dont know if it might amplify the stuttering. I think i had less lags without mounts and pets on the map.

On a 4050 laptop GPU you should start with all settings at the lowest. Your settings are cranked up far too high for that GPU. Set everything to low, turn on frame generation, and keep those RTX settings turned off. Set the texture streaming poolsize to 2000, and turn on PCSS shadow filter method since you're also using DLSS. If everything works fine at the lowest settings, then start turning up settings one at a time until you reach a balance of quality and performance.

Pets and mounts definitely worsen the situation. They even warn you in the load-out menu about possible performance issues related to overcrowding with pets. Servers and multiplayer are even worse.

Not saying this is an issue but disabling c states for cpu can be beneficial for stuttering. Bios

Notice however how he said "without even touching voxels nor placing deployables/constructs." This is the more interesting part to me imo. Anyone that has 500+ hours on this game and has played open world like the rest of us knows the aches and pains of performance on them. HOWEVER, it seems allot of us have been mislead to believe it is due to how the game processes harvested voxles/buildables/mounts placed in the world. YET he still is having these issues on a FRESH open world. THAT is a very very big flaw if you ask me, I think open worlds specifically need to be analyzed better and optimized more.

I know the Icarus team does everything they can, but it might be time for a big overhaul update besides these smaller ones we usually get. I think if they didnt give us our weekly updates for 2-3 months in trade for a much better optimized game engine, they wouldnt make anyone upset/lose their community. I think it would bring the game back big time, especially if they decide to go the console/steam deck route. If you do a quick google search and just type "icarus performance" you will find LOADS of pages filled with that being their top complaints, even on the steam forums.

Icarus is a fantastic game, but its performance plagues will be the bane of its life because it scares so many new players & their friends off. You can find posts such as "I wont touch that game, same crashing in the game/performance issues for years" Those kinds of comments really do harm to the game & its community. I love Icarus and think its literally the No mans sky of survival games in terms of Developer love/community passion for the game & the amount of content poured into it. But it feels like we are beating around the bush to try to make Icarus even better with all these small updates, without addressing the only real primary issue with the game.

I have 522hrs on Icarus and the only complaint that has been consistent since early access is performance.

The count of animation matters when making assets

If your unsure what this means it is every asset
