Yesterday in EKT server in, as the log says, Mesa ii, we suffered mass crash that left only 5 or less people in the server. This is the partition of the log that I believe is the one needed to be looked at. I can provide the complete log, but it might take some time.

Also, I noticed that there's no DX11 support in the game. I've tried doing -dx11 command and the screen went black upon entering. After checking the log, I get the impression that the shaders aren't compiled for dx11 as of yet

I forcibly closed the game however, so... I can't be sure for certain. Is there anyone else who managed to run this with dx11?
