I have the same problem. Even tried to play on older drivers. Formatted my pc. and everything. I cant do anything to fix it.
Even tried to talk on the Rust discord but no luck there. just many trolls there.
So what I have done:
Reinstalled rust several times - NO FIX
Reinstalled computer fully - NO FIX
Reinstalled Drivers - NO FIX
Roll back driver to when rust was running just fine - No FIX
My pc specc ingame:
Task manager:
So I am 100% sure theres a problem with the rust client and not from my end.
Maybe we can get some help?
Appears Rust is using your CPU integrated graphics rather than your dedicated GPU from the screenshots shown. You'd need to force Rust to use your dedicated GPU.
Google "laptop not using dedicated gpu" should have multiple tutorials on how to resolve this issue.
