first let me apologize as im writing this on behalf of my friends so i cant list full specs. but it is running optimal hardware, i think a gtx 1070, 24gb ram, and a modern processor. the problem is we play plenty of games with no issues, COD: MW, Ark, GTA, but whenever we try and play on our Minecraft server, his PC will crash within seconds of joining the server.
the other weird thing is, he is able to play single player Minecraft with no issue, and even mod packs. but whenever we try and play together and join a server ran on my PC, he crashes, and none of my other friends do (so its not an issue with my server). this happened to us last year and we gave up on playing Minecraft. we tried to revisit it today and the same problem occured, even though this has never been run into on other games.
