Are you using the latest driver? 17.11.4?
Ya, i have tried just about all previous drivers since the Rx 580 came out and nothing seems to work.
I am currently on 17.11.4
crossfire works fine on my old R9 270's
Just doesnt work on my RX 480s or 580's
Optimized 1x1 uses a pre-defined set of instructions, flickering can be expected if it does not work well with the application in question.
I would suggest trying other Custom profiles like AFR Compatible, Friendly, or even trying an exisitng CrossFire profile for a different game altogether.
As said in the topic i have tried many different configs and stuff. Anyways i stopped using AMD Gpus as of today when my Evga GTX 1080ti SC Blackedition gets delivered.
Everything is fixed now in my own opinion now. Just hate that i have to go green team after 10 years of using AMD gpus since 3000 series and crossfire configurations since the 6000 series all way up to RX 580. I never had this many problems with crossfire. I just have seen better support for it on older generations before the rx 400 series. If amd releases a Good 4k alternative to compete with nvidia's top line in, performance, reliability, and support i will come back.
Anyways thanks for the response
