Only had one CTD during a MP session which I think was the server I was on crashing. Everything else has been butter smooth for me. Performance isnt quite what I wanted but it runs a bit better than GTA5 did and I am running 2560*1080. I was running 3840*1280 but the performance at that resolution wasnt optimal lol. So I backed it back down to a standard sub4k 21:9

Im enjoying it and once they patch it a bit more Im sure it will just get better.
