[2023] Cannot join to a server

Originally posted by boggler: I have the same problem, game starts normally, but as soon as I want to enter a world, I have a CTD.

This happens after the world has been loaded to 100%.

The problem only appears with version 10.

Graphics driver is up to date, graphics settings are set to default.

I have deactivated all special features in the settings (Twitch and so on)

Started the game with admin rights.

Reinstalled the game several times, deleted old files in the appdata and documents folders. Verified installation files.

The only thing that works is a rollback to the 10.0 versions.

I am now at a loss and grateful for any tips.

That and OP's problem is likely due to a too old CPU, see our statement on discord:

PSA: For the unity crashes seen on joining a world the problem is the usage of very old CPU's that do not support the AVX2 / SSE4 instructions that are required in the new Unity version we use. Those CPU's are all below our minimum requirements, but we will do our best to find a way to enable you to play nontheless. We are reaching out to players affected to test a variety of options we have via custom builds. We'll let you know if we can find a solution that works for everyone.

We can only find out by you sending your logs after a crash to [email protected], though: https://github.com/StrangeLoopGames/EcoIssues/wiki/Getting-the-Eco-game-log-file

We are also working on a workaround-fix, there is a branch "old_hardware_test_1" that does seem to remedy the problem for most people with this issue. We cannot include the fix in the general game release until we're back in full force to do some performance testing, though, as the fix can affect performance of people with normal cpus.

You are correct about the technical details. Unity intends to fix the problem with choosing a correct instruction set themselves, but as usual it is unknown when that may be the case. It's not going to be anytime soon, though.

Deleting files does always happen on your own risk, though. You will not receive any support for that.

Yes, they are built 2009 (iirc) and don't support today's common instruction sets.
